Answer:

Slope = -4/7

Step-by-step explanation:

The slope of a line is determined by the formula m = (y2 - y1) / (x2 - x1), where m is the slope of the line, (x1, y1) and (x2, y2) are two points on the line. Plugging in the values from the given points, we get:

m = (7 - 3) / (1 - 8) = 4 / -7 = -4/7

Therefore, the slope of the line that passes through (8,3) and (1,7) is -4/7.

Answer:

5 letters

Step-by-step explanation:

let x = # of packages

x+2 = # of letters

$0.37(x+2) + $0.88x = $4.49

.37x + .74 + .88x = 4.493

1.25x + .74 = 4.49

1.25x = 3.75

x = 3.75/1.25 = 3 = # of packages

# of letters = x+2 = 3+2 = 5

There is no percentage of 1 2, as percentages are a fraction of 100 and 1 2 is not a fraction.

A percentage is a fraction of 100, while 1 2 is not a fraction. Therefore, there is no percentage of 1 2.A percentage is a way to express a number as a fraction of 100. For example, 25% is equivalent to the fraction 25/100. However, 1 2 is not a fraction, and therefore cannot be expressed as a percentage.1 2 can be expanded to 100 by multiplying both numerator and denominator by 50. 1 2 would then be equal to 50/100, or 50%.

The slope formula generally used in the 7th grade is as follows -

1. The Point slope form -

Suppose you are given two points (x1,y1)  and (x2,y2) or a graph consisting of two points whose slope is asked, then you use this method.

These points are often intercepts of the x and/or y axes.

Here you can use the formula for the equation of the slope which is -

m= (y2−y1) / (x2−x1).

2. The Slope-intercept Form-

Here, you are given the linear equation that is in the form y=mx+b.

If not you can manipulate it into that form.

Now, the slope here is m which is the coefficient of x.

What is Permutation?

In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order. In other words, if the set is already ordered, then the rearranging of its elements is called the process of permuting. Permutations occur, in more or less prominent ways, in almost every area of mathematics. They often arise when different orderings on certain finite sets are considered.

What is a Combination?

The combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection or k-combination with repetition are often used.

If the combination begins with an odd digit

We have    3 * 2 * 3 * 2 * 3   =   108  possible  combinations

If  the combination  starts  with an even digit

We have  2 * 3 * 2 * 3 * 2 =   72  possible combinations

So 108  +  72  = 180  possible  combinations

Answer: x =24

Step-by-step explanation:

3(2x-5)-4x=33

6x - 15 -4x = 33

2x - 15 = 33

2x = 48

x = 24

Answer:

x = 24

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(2x−5)−4x=33

(3)(2x)+(3)(−5)+−4x=33(Distribute)

6x+−15+−4x=33

(6x+−4x)+(−15)=33(Combine Like Terms)

2x+−15=33

2x−15=33

Step 2: Add 15 to both sides.

2x−15+15=33+15

2x=48

Step 3: Divide both sides by 2.

2x/2 = 48/2

x = 24

Answer:

-0.5

Step-by-step explanation:

3(2x+9)=24

Distribute the 3

3(2x)+3(9)=24

Subtract both sides by 27

6x= -3

Divide both sides by 6

x= -0.5

Answer:

x = -1/2

Step-by-step explanation:

Given equation,

→ 3(2x + 9) = 24

Now the value of x will be,

→ 3(2x + 9) = 24

→ 6x + 27 = 24

→ 6x = 24 - 27

→ 6x = -3

→ x = -3/6

→ [ x = -1/2 ]

Hence, the value of x is -1/2.

Answer:

x = 4, y = –5

Step-by-step explanation:

2x = 18 --------(1)

x-5y = 29. -------(2)

x = 5y + 29 -----(3)

just substitute for x in equation 1

2( 5y + 29) = 18

10y + 58 = 18

10y = 18 – 58

10y = –50

y = –5

since y = –5 we will just substitute for y in equation (2)

x = 5(–5) + 29

x = –25 + 29

x = + 4

Let's check if our answer is correct

x – 5y = 29

4 – 5(–5) = 29

4 + 25 = 29

29 = 29

True. The pessimistic approach assumes that the worst-case scenario for each alternative will occur and chooses the best of these.

An optimistic approach indicates that the decision-makers believe the outcomes will benefit the organisation. A pessimistic approach, on the other hand, indicates that the decision-makers are convinced that the outcomes will be detrimental to them. The pessimistic approach allows decision-makers to plan for the worst-case scenario. In the optimistic approach, decision-makers believe that the alternatives chosen will produce the best results. In other words, the decision-makers are confident that their options are the best for the circumstances. The pessimistic approach is characterised by decision-makers assuming that the choices they make will have the most negative outcomes.

Thus, the pessimistic approach is the approach which is used to assume the worst possible outcomes for each alternative will occur.

Equation: 154 = 158n - 132 n = 11/6

Step-by-step explanation:

Let's start by converting this into an equation. Some keywords to look for are "is" which means an equal sign (=), "product" which is multiplication (*), and "decreased" which means a minus sign (-):

So this is our equation: 154 = 158n - 132

Now we have to solve for n:

First, we add 132 to both sides to isolate the n more:

286 = 158n

Then to completely isolate the n, we divide both sides by 158

286

------    =     n

156

n = 11/6, final answer.

Answer:

y = 3x + 2

Step-by-step explanation:

y = 3x + c

substitute x and y with one of the points (ex: (1,5)):

5 = 3(1) + c

5 - 3 = c

2 = c

so

y = 3x + 2

To make sure this is correct, substitute x and y with the other point (ex: (-3,-7)):

-7 = 3(-3) +2

-7 = -9 + 2

-7 = -7

that means the equation is true and as it passes through both points.

To solve the given inequality we use the elimination method.

Multiply equation 1 by 4 on both side, we get;

4x+4y≥8...................(3)

Subtract equation 3 and 2, we get;
