Please i really just need help :(

A

Step-by-step explanation:

slope-intercept formula is

y=mx+b

(m) is slope [amount of change]

(b) is y intercept [starting amount]

y=10r+8.25

apply the "392.50 they gave in place of (y)

392.50=10r+8.25

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

step-by-step explanation:

mean or average is 40.6
