E = 17h + 150
E is her total earnings
H is the hours she work
The 150 is her bonus so we add that to her hours worked

Answer:

150 + 17x = y

x = hours worked

y = her overall profit

A book club charges a membership fee of $20 and then $12 for each book purchased. Write a function to represent the change, y, o

riadik2000 [5.3K]

It is y = 12x + 20.
You start with 20 as the y-intercept because that is the starting amount that you paid. The constant rate of change is 12 dollars per book. So, 12 time however many books written as 12x. Hope that helps! :)

25 Pts + Brainliest for the first correct answer.

Answer:

25. x=19

26. 16=x

27 28=x

28. 24=x

Step-by-step explanation:

25. The two angles make a straight line (180 degrees)

6x-17 + 3x+26 = 180

Combine like terms

9x +9 = 180

Subtract 9 from each side

9x+9-9=180-9

9x = 171

Divide by 9

9x/9 = 171/9

x=19

26. These angles are corresponding angles and corresponding angles are equal if the lines are parallel

4x+20 = 6x-12

Subtract 4x from each side

4x-4x+20 = 6x-4x-12

20 =2x-12

Add 12 to each side

20+12 = 2x-12+12

32=2x

Divide by 2

32/2 = 2x/2

16=x

27 These are alternate interior angles and alternate interior angles are equal if the lines are parallel.

4x+30 = 6x-26

Subtract 4x from each side

4x-4x+30 = 6x-4x-26

30 = 2x-26

Add 26 to each side

30+26 =2x-26+26

56= 2x

Divide by 2

56/2 = 2x/2

28=x

28. These are corresponding angles and corresponding angles are equal if the lines are parallel.

99=3x+27

Subtract 27 from each side

99-27 = 3x+27-27

72 = 3x

Divide by 3

72/3 = 3x/3

24=x

$676.

If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation

Original price * 25% = $169

To solve for the original price:

Original price = $169/.25 = $676.
