2b - 6 = -4
2b = -4 + 6
2b = 2
b = 2/2
b = 1
When y=0.8
4x +8(0.8) =40
-> 4x +6.4 =40
-> 4x = 33.4
-> x=33.4/4
-> x=8.35
Hope it helps...

Answer:
1440.08 mi
Step-by-step explanation:
Pythagorean Theorem:
= 1440.08
x₁ = 0
x₂ = 6
9x² - 54x = 0
9x(x - 6) = 0
x(x - 6) = 0
x = 0
x - 6 = 0 → x = 6
Hope this helps! :)
