question 2
which statement shows the correct justification for the step used to solve the equation?
add 8 to each side.
add 10 to each side.
subtract 8 from each side.
subtract 10 from each side.

Step-by-step explanation:

r+(−8)=10

r - 8 = 10

r = 10 + 8

r = 18

(substract 8 from 1 side and add it to the other side )

false

inverse variation is not exponential

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
