the slope is y=5/2x-12

Answer:

15 people

Step-by-step explanation:

We are told that there are 90 males and 75 females.

This question is a greatest common factor question.

We find the factors of 75 and 90

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Then the greatest common factor is 15.

The greatest number of people that can be in each group is 15

Step-by-step explanation:

x−7(x−2)=10x+9−x

Step 1: Simplify both sides of the equation.

x−7(x−2)=10x+9−x

x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)

x+−7x+14=10x+9+−x

(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)

−6x+14=9x+9

−6x+14=9x+9

Step 2: Subtract 9x from both sides.

−6x+14−9x=9x+9−9x

−15x+14=9

Step 3: Subtract 14 from both sides.

−15x+14−14=9−14

−15x=−5

Step 4: Divide both sides by -15.

−15x−15=−5−15

Answer:

Step-by-step explanation:

if 12x= 4(x+5), x equals...

distribute the 4 to the x and

12x = 4x + 20

subtract the 4x on both sides

8x = 20

divide by 8

x = 20/8

simplify

x = 5/2

5/2 = 2.5 so the answer is D

Answer:

Answer:

He bought 12 books.

Step-by-step explanation:

Here is your equation: 6 b+3=75

Step 1- Subtract 3 from both sides: 6 b+3-3=75-3

6 b=72

Step 2- Divide by 6: 6 b/6=72/6

b = 12 books in total.

Answer: x=0.15

Step-by-step explanation:

5x+0.25=7x-0.05

5x+0.25-0.25=7x-0.05-0.25

5x=7x-0.3

5x-7x=7x-0.3-7x

-2x=-0.3

-2x/-2 = -0.3/-2

X=0.15

Answer:

They made 342 dollars profit and only buyed them for 10 dollars each

Step-by-step explanation:

$2.80 each sweater

Step-by-step explanation:

Forget the 190, it is not necessary. We are focusing on 19, and 532.

To get the answer, divide 190 by 532. (532 / 190) you will get 2.80. That's how much profit the store makes per sweater.

Answer:

Slope:1

Step-by-step explanation:

When finding the slope from 2 points, you subtract them y/x

(-6,3)

(-4,5)

-2,-2

Slope: (-2,-2)=1

y=x+b

Insert on of the the points, in this case, I will choose -6,3

3=-6+b

b=9

So slope intercept form, the answer will be y=x+9.

Since you are just finding the slope, the answer is just 1.

The slope of the line that contains the points:(-6, 3) and (-4,5) is 1.

You could be asked to determine a line's slope when working with linear equations. Knowing the slope formula in that situation is really helpful. Watch this lesson to learn the formula for calculating the slope of a line.

Given the coordinate of the line (-6, 3) and (-4,5).

Hence from the formula of the slope (m) =  [tex]\frac{y2 - y1}{x2 - x1}[/tex]

m = (5 - 3) / (-4 + 6)

m = 1

Therefore the slope of the line that contains the given points is 1.

Q2 B is the answer

Answer:

sample answer:   If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4

Step-by-step explanation:

The situation is a representation of the linear function.

Given that,

One dollar is divided into four quarters.

The total number of dollars is a function of the number of quarters.

Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value

As a result, the slope should be 1/4.

y = 1/4x should be the linear function.

Hence, As a result, we can conclude that the situation is a linear function.
