You isolate the variable (a)
-3a = -18
/-3
a = 6
The answer is <span>6.7 miles further.</span>
It is given:

Wyatt’s eye-level height - h₁<span> = 120ft
</span>Shawn’s eye-level height - h₂<span> = 270ft
The distance that Wyatt can see:
</span>

<span>The distance that Shawn can see:
</span>

The question is how <span>much farther can Shawn see to the horizon, so we need to subtract the results:
20.12 - 13.42 = 6.7 miles</span>
Answer: 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
(h, k) = (4, 8)
(y - k) = a(x - h)²
(y - 8) = a(x - 4)²
y = a(x - 4)² + 8
plug in one of the x intercepts (or any other known point on the curve)
0 = a(2 - 4)² + 8
0 = a(4) + 8
a = -2
y = -2(x - 4)² + 8 fourth option.
X+x-x+y+y-z+z-z is equal to x+2y-z (combining like terms)
