What is a slope in math?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

To find the correct answer, we need to look at the formula for a straight line: y=mx+b where m= the slope of the line and b= the y intercept. We know from the problem that the slope must be equal to -4, leaving us with y= -4x +b. From here you can substitute the given point in the equation and solve for b.

-3= -4(4) +b

-3= -16+b

+16  +16

13= b

This tells us that b=13, now we simply substitute that into the formula.

The solution to your question is y=-4x+13

Answer:

This is the slope intercept formula used for make a line graph

Step-by-step explanation:

In the expression:

y = mx + b

m will equal your slope which is represented by rise/run

Example: 1/2, 2, 5, 3/8 etc.

b represents your y-intercept which is the point where the line hits the y-axis

For example: if the y - intercept is -2 then your line graph will cross through (0,-2) in the coordinate plane

All together, the equation for the line would look something like:

y = 1/2x - 2

The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 152 when R'(x) = 0.06x² - 0.05x + 152.

Given that,

We have to find for the marginal revenue function, locate the demand function.

Remember that the income is zero if no things are sold:

R'(x) = 0.06x² - 0.05x + 152

p(x) is what.

We know that,

MR = dTR/dx = 0.06x² - 0.05x + 152

Integrating the marginal revenue function , we get total revenue function,

MR = TR

= (0.06x²⁺¹)/(2+1) - (0.05x¹⁺¹)/(1+1) + 152x

= (0.06x³)/3 - (0.05x²)/2 + 152 x

TR  = 0.02 x³ - 0.025 x² + 152 x

TR = (P)(Q) = (P)(x) =  0.02 x³ - 0.025 x² + 152 x

P = ( 0.02 x³ - 0.025 x² + 152 x)/x

P = 0.02x² -0.025x + 152

Therefore, The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 152 when R'(x) = 0.06x² - 0.05x + 152.

Answer:

y = [tex]-\frac{1}{2}[/tex]x + 1

Step-by-step explanation:

y = mx + c

Find the reciprocal and change the sign of the gradient (m), which is -[tex]\frac{1}{2}[/tex]

so

y = [tex]-\frac{1}{2}[/tex]x + c

Put in your point that you want it to intersect (4,-1):

-1 =   [tex]-\frac{1}{2}[/tex](4) + c

-1 = -2 + c

-1 + 2 = c

1 = c

y = [tex]-\frac{1}{2}[/tex]x + 1

As per the question, Total Annual Cash Inflows = 5000, Discount Factor = 3.72 and New Machine's internal rate of return = 16%

Note: The query is not complete and does not contain the necessary information for part 4. It is impossible to fully answer this question without the exhibits stated in the questions. Up until part 3, we will be solving it.

1) The entire annual cash inflows must be calculated for this, and the formula is given below:

Total annual cash inflows are equal to the annual savings from part-time labor plus the additional contribution margin from anticipated sales.

Annual Cash Inflows Total = 3800 + ( 1000 x 1.20)

= 3800 + 1200

= 5000

2. Formula for figuring up the discount percentage:

Discount Factor = New Machine Price/Annual Cash Flow

M(5) = 2737.867; After 5 years, there are approximately 2,737 members in the company

What does M(5) mean and how should it be interpreted in relation to the issue?

In this case, we know that the exponential function M(t) = 1700*(1.10)t denotes the number of members the company had t years after its founding.

Then, M(5) will stand for the number of members who joined the company five years after its founding. To determine this value, all we have to do is substitute the number five for the variable t.

M(5) = 1700*(1.10)^5 = 2,737.867

Rounding to the nearest whole number, we obtain 2,737, which indicates that there will be roughly 2,737 members after 5 years.

Consequently, the second choice is the right one:

"M(5) = 2737.867; There are about 2,737 members in the company after 5 years."

The solutions for a and b are given below by using probability:

According to the central limit theorem, regardless of the underlying distribution, the distribution of the sum (or average) of a large number of independently distributed variables will be roughly normal. According to the central limit theorem, if you take sufficiently large random samples from a population with mean and standard deviation and replace some of the individuals in the samples, the sample means will be distributed about normally. The central limit theorem in probability theory proves that, even when independent random variables are added together, their correctly normalized sum frequently tends toward a normal distribution.

As a result, the sampling distribution of the sample mean of 22 passengers is normally distributed, with a mean weight of 190 pounds that is the same as the population's mean σ/√n.

Answer:

Since the number of calories burned is proportional to the number of minutes jogged, we can represent this relationship using the equation y = kx, where y is the number of calories burned, x is the number of minutes jogged, and k is the constant of proportionality.

To find the value of k, we can use one of the given data points. For example, if x = 10 and y = 95, we have 95 = k * 10. Solving for k, we find that k = 9.5.

The constant of proportionality, k, has the meaning of the number of calories burned per minute of jogging. In this case, k = 9.5 calories/minute, so for every minute of jogging, the person burns 9.5 calories.

The parallel line has an equation of y = 2x - 21

The equation is given as

y = 2x + 3

The equation of a line can be represented as

y = mx + c

Where

slope = m

By comparing the equations, we have:

m = 2

The slopes of parallel lines are equal

This means that the slope of the other line is 2

i.e. m = 2

Recall that:

The equation of a line can be represented as

y = mx + c

Where

slope = m = 2

Also, we have

(x, y) = (6, -9)

So, we have

-9 = 2 * 6 + c

Your answer is B) [tex]y=\frac{1}{3}x-6[/tex]

By using substitution method the values of x and y are, x = -1/7 and y = -32/7.

What is substitution method?

The substitution method is typically used in mathematics to solve an equation system. In this approach, you solve the equation for one variable first, then you enter its value into the other equation.

Consider, the given equations

-8x = 5y + 24       ..(1)

-9y = 40 - 8x        ..(2)

From equation (1),

x = -(5y + 24)/8

x = -5/8y - 3            ..(3)

Plug value of x in equation (2),

-9y = 40 - 8(-5/8y - 3)

-9y = 40 + 5y + 24

-14y = 64

y = -64/14

y = -32/7

Plug y = -32/7 in equation (3)

x = -5/8(-32/7) - 3

x = -1/7

Hence, by using substitution method the values of x and y are, x = -1/7 and y = -32/7.

Answer:

Step-by-step explanation:

The required probability is 0.75 that a student visited the athletic complex regularly, given that he or she tried out for a sport.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

To find the probability that a student visited the athletic complex regularly, given that he or she tried out for a sport. This is known as the conditional probability of visiting the athletic complex regularly, given that the student tried out for a sport.

The formula for calculating conditional probability is:

P(A|B) = P(A and B) / P(B)

In this case, A is the event "visited the athletic complex regularly" and B is the event "tried out for a sport."

Substituting the given probabilities into the formula, we get:

P(A|B) = P(A and B) / P(B)

= 0.12 / 0.16

= 0.75

Therefore, the probability is 0.75, which is the correct answer that would be option (C).

Step-by-step explanation:

Since there are 4 woman in total, there are 14-4=10 men.

Part 1

They can choose either 2 women, 3 women, or 4 woman.

If they choose 2 out of the 4 woman, they can have 6 different combinations.

4!/(2!(4-2)!)

=24/(2(2!))

=24/4=6

There are 8 remaining men to be chosen on the committee (because 10-2=8).

There are 10 total men and 8 men need to be chosen out of them, so the number of combinations for men is given below.

10!/(8!(10-8)!)

=10!/(8!(2!))

Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 8! from both the numerator and denominator to simplify it. This leaves the numerator with 9x10, which is 90, and the denominator with 2!, which is just 2.

90/2=45

Now we need to multiply 45 (number of combinations to choose 8 men from 10 men) and 6 (number of combinations to choose 2 women from 4 woman).

45x6=270 combinations if 2 woman are chosen

Part 2

Next we need to find out how many combinations there are if they choose 3 women for the committee.

If they choose 3 out of the 4 woman, they can have 4 different combinations.

4!/(3!(4-3)!)

=24/(6(1!))

=24/6=4

There are 7 remaining men to be chosen on the committee (because 10-3=7).

There are 10 total men and 7 men need to be chosen out of them, so the number of combinations for men is given below.

10!/(7!(10-7)!)

=10!/(7!(3!))

Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 7! from both the numerator and denominator to simplify it. This leaves the numerator with 8x9x10, which is 720, and the denominator with 3!, which is 6.

720/6=120

Now we need to multiply 120 (number of combinations to choose 7 men from 10 men) and 4 (number of combinations to choose 3 women from 4 woman).

120x4=480 total combinations if 3 women are chosen

Part 3

If 4 women out of 4 women are chosen for the committee, then obviously, there will only be 1 combination for that, since all the women will be chosen.

This leaves us with 10-4=6 spots for men in the committee.

There are 10 total men and 6 men need to be chosen out of them, so the number of combinations for men is given below.

10!/(6!(10-6)!)

=10!/(6!(4!))

Instead of multiplying out 1x2x3x4x5x6x7x8x9x10 to find 10!, we can divide 6! from both the numerator and denominator to simplify it. This leaves the numerator with 7x8x9x10, which is 5040, and the denominator with 4!, which is 24.

5040/24=210

Now we need to multiply 210 (number of combinations to choose 6 men from 10 men) and 1 (number of combinations to choose 4 women from 4 woman).

210x1=210 total combinations if 3 women are chosen

Part 4

Finally, we need to add all the final answers from the previous parts.

270+480+210=960 total combinations if at least 2 women were chosen for the committee
