I need help with this practice problem solving. It asks to graph the function yourselfIf you can, use desmos.

We use the followig property of triangles:

• One side cannot be equal or greater than the sum of the other two sides

The sides of this triangle are: 11, 9 and 17.

The sum of the first two sides is: 11+9=20

The sum of the two sides is greater than the other remaining side (17).

Thus, 11, 9 and 17 do not make a triangle.

Loan=$278 at 10%

A simple interest is calculated for payments on the initial capital.

If the total interest was $174.12.

If the interest is on a year. You calculated the interes of one year. The 10% of $278:

In a year the interest is $27.8.

Then, $174.12 divided into $27.8 is the number of years of the loan:

Answer:

Step-by-step explanation:

1. Subtract 200 from 180

200 - 180 = 20

2. Divide the difference of the number of bookmarks by last years

20 / 200 = 0.1

3. Multiply 0.1 by 100 to get the percentage

0.1 x 100 = 10 %

4. Since this is a reduction in number of bookmarks sold, then it would be a -10% change in the number of bookmarks sold.

The mass of the petrol is 8.88 kg.

Given, Petrol has a density of 740 kg/m³.

A container holds 12 litres of petrol.

One litre is equal to 0.001 m³.

As, Density = Mass/Volume

1 litre = 0.001 m³

12 litres = 0.012 m³

Now, using the formula, we get

740 = mass/0.012

mass = 740×0.012

mass = 8.88 kg

Hence, the mass of the petrol is 8.88 kg.

The amount of each deposit is $210000

Compound interest is when you reinvest your income. Compound interest distinctively means "interest on interest" and is the reason so many investors are so successful.

The computation of the each deposit is shown below:

Given that

Future value be $70,000

Time period = 10 × 2 = 20

And, the rate = 9% ÷ 2 = 4.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($70,000 × 4.5) ÷ (1 + 0.025)²⁰⁻¹

= $315,000 ÷ 1.5

= $210000

SOLUTION

Let's look at the graphical solution of the pair of simultaneous equations

From the graph, we can see that the equations have at least one solution, which are 2.556, and -0.333. Hence, it is said to be consistent.

Now, since the solutions intersect only at one place, it means that it has exactly one solution. If a consistent equation has exactly one solution, it is said to be independent.

Therefore, the systems of equations are consistent and independent

The answer, the measure of the smallest angle is 39° in the triangle.

What is are of triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

The sum of all angle of triangle = 180

Let x be the smalletst angle

2nd angle will be x+24

and 3rd angle will be 2x

So sum of all angles x+2x+x+24=180

4x=180-24

x=156/4

x=39

Hence the measure of the smallest angle will be 39°

Step 1: For solving this exercise, we need to know the speed of sound. We will calculate it this way:

Speed = Distance/Time

Replacing with the values Josh has.

Speed = 5 miles/12 seconds

Speed = 0.417 miles per second

Step 2: Now, let's calculate the distance after 7 seconds:

Using the same formula, we can find the distance, as follows:

Distance = Speed * Time

Distance = 0.417 * 7

Distance = 2.919

Distance = 3 miles (Rounding to the nearest whole number)

Step 3: Interpretation of the answer, as follows:

The lightning was 3 miles away when Josh counted 7 seconds between the next flash of lightning and thunder.

Answer:

The length of the playground = 11 yards

The width of the playground = 14 yards

Explanation:

Let the length of the playground = l yd.

The width of the playground is 3 yd longer than its length.

Therefore, the width of the playground = (l+3) yd

Area of a Rectangle = Length x Width

Substituting the given values, we have:

We then solve the equation above for l.

We factorize:

The length of the playground = 11 yards

The width of the playground = 14 yards

Using the concept of ratio and proportion, the vendor sold 56 cups of hot cider.

The word "proportion" often denotes a portion, share, or sum that is in comparison to a whole. Two ratios are in proportion when they are equal, according to the proportional idea. When an equation or a statement to that effect is used, two ratios or fractions are equal.

A percentage is a mathematical comparison of two numbers. In terms of proportion, two sets of given numbers are said to rise or decrease in the same ratio if they are directly proportionate to one another.

Cider supplied by the street seller for value = x for 35

= x/35

The cider's ratio is 8:5,

x/35 :: 8:5,

x = [35(8)]/ 5

The amount spent on brother is $16, on sister is $26 and that on wife is $58.

According to the question,

We have the following information:

Mark is buying Christmas presents for members of his family. He wants to spend $10 less on his brother than he spends on his sister, and six dollars more than twice the amount he spends on his sister on his wife. And Mark

has $100 to spend.

Let's take the amount spent on sister to $s.

Amount spent on brother = $(s-10)

Amount spent on wife = $(6+2s)

So, we have the following expression:

s+s-10+6+2s = 100

4s-4 = 100

4s = 104

s = 104/4

s = $26

Amount spent on brother = 26-10 = 16

Amount spent on wife = 6+2*26

Amount spent on wife = 6+52

Amount spent on wife = $58

Hence, the amount spent on brother is $16, on sister is $26 and that on wife is $58.

Equation of a line in slope intercept form:

m is the slope

b is the y-intercept

To find the slope use the two given points in the next formula:

Use the slope and one of the points to find the y-intercept:

Then, the equation of the line passing through the given pair of points is:

Answer:

y = -2x - 4

Step-by-step explanation:

Slope intercept form : y = mx + b

Where

The y intercept is the point where the line crosses the y axis.

Here, just by looking at the graph we can say that the y intercept is at (0,-4) because that is where the line passes the y intercept.

This means that b = - 4

We can find the slope using the following formula

Slope = (y2-y1)/(x2-x1)

Where, (x1,y1) and (x2,y2) are any given points on the line

The points used can vary however I have chosen (0,-4) and (-2,0)

Defining our variables we get (x1,y1) = (0,-4) and (x2,y2) = (-2,0)

So we have x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0

We now plug this in to the formula

Slope = (y2-y1)/(x2-x1)

==> plug in x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0

Slope = (0-(-4))/(-2-0)

==> remove parenthesis

Slope = (0+4)/(-2-0)

==> simplify addition and subtraction

Slope = 4/-2

==> simplify fraction

Slope = -2

So the slope or "m" is -2

Again we have y = mx + b

m = slope so m = -2 and b = y intercept so b = -4

Plugging this in, we acquire y = -2x - 4

A linear equation has the algebraic form y=mx+b, where m is the slope and b is the y-intercept, and consists of a first-order (linear) term and a constant. When x and y are the variables, the aforementioned is sometimes referred to as a "linear equation of two variables."

Each line in the Euclidean plane is conceived of as a collection of all the answers to a linear equation with two variables. Lines represent the solutions of linear equations in the Euclidean plane. This is where the word "linear," which is used to characterize this class of equations, originates.

If f(x) has a remainder of -2 when divided by x-7, f(7) is -2.

The leftover is -2 when the function f(x) is divided by x-7, according to the question.

hence the result will be -2 if we use the value x = 7 in the function.

This has the same meaning as "f(7)" because "f(7)" also means to enter "x = 7" in the function and "-2" as the response.

Therefore, if f(x) is divided by x-7 with a remainder of 2, f(7) is equal to -2.
