Vertex: (3,-65) axis of Symmetry: x = 3
Answer:
if he drove 9 hours it would 378 miles
The slope-intercept form:

m - slope
b - y-intercept
We have the slope m = 4 → 
and point (1, 6). Substitute:

<em>subtract 4 from both sides</em>

<h3>Answer: y = 4x + 2</h3>
Answer:
3
Step-by-step explanation:
The factor (x - 8) has 1 zero at x = 8
The factor (x + 3)² has a zero at x = - 3 of multiplicity 2
In total there are 3 zeros
Answer is c.
t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h
