Find the slope of the line passing through the points (-4, -4) and (2, 5)

1 answer:

5 0

Answer: 3/2

Explanation:
To find the slope we plug in the given numbers into the equation y2-y1/x2-x1 which means when plug in our equation looks like this: 5-(-4)/2-(-4)
5-(-4) is 9
2-(-4) is 6
We now have 9/6 which we can reduce by 3 or you can also figure this out by dividing 9 by 6.
This leaves us with our slope which is 3/2

Isaiah and Wanda both went bowling last weekend, but not together. Isaiah went during open bowling time, paying $16 for shoe ren

DIA [1.3K]

Answer:

1 hour

Step-by-step explanation:

Let the number of hours bowled by Isaiah and Wanda be X

Isaiah spent 16 dollars on shoe rental and 2X on bowling

Wanda spent 13 dollars on shoe rental and 5X on bowling

Since they spent the same amount, set up an equation

16+2X=13+5X

subtract 2X on either side, then subtract 13 from either side we get

3X=3

divide both sides by 3

X=1

How to get answer:

$Expand -2\left(x+13\right)+9x:\quad 7x-26\\Expand -2\left(x+13\right):\quad -2x-26\\\\=-2x-26+9x\\Simplify -2x-26+9x:\quad 7x-26\\7x-26=4\\\mathrm{Add\:}26\mathrm{\:to\:both\:sides}\\7x-26+26=4+26\\\mathrm{Simplify}\\7x=30\\\\\mathrm{Divide\:both\:sides\:by\:}7\\\frac{7x}{7}=\frac{30}{7}\\Simplify\\x=\frac{30}{7}$
