Answer:

y = 5x+7

Step-by-step explanation:

Parallel lines have the same slope so y = 5x+9 is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope is 5

The new line will have a slope of 5

y = 5x+b

We know a point on the line (-2,-3)

Substitute this point into the equation

-3 = 5(-2)+b

-3 = -10+b

-3+10 = b

7 = b

y = 5x+7

HELP!! WITH THESES MATH QUESTION! WILL MARK BRAINLIEST 70 POINTS!!! PLEASE HELP
Cloud [144]

1. Let hardcover books = X

Paperback books would be 4x -3 ( 3 less than 4 times)

Now you have:

X + 4x-3 = 447

Simplify:

5x - 3 = 447

Add 3 to each side:

5x = 450

Divide both sides by 5:

x = 450/5

x = 90

He has 90 hardcover books.

2. 300 miles / 25 miles per gallon = 12 gallons of gas.

12 gallons x $$ per gallon = $48 dollars

3. Subtract base pay from total:

1916 - 800 = 1,116 worth of commissions.

Divide commissions by percentage:

1116 / 0.09 = $12,400 total sales.

4.

Find the median of the heights: 65-50 = 15. 15/2 = 7.5

Median = 50+7.5 = 57.5

The equation would be |h-57.5| < 7.5
