Answer:
13 means the starting number
13 is the y-intercept (0,13)
Hahaha anyway thanks for the free point
The answer will be
-1.8h=-7.2-8.1
h=-15.3/-1.8
h=8.5
Find the vertex by using the formula -b/2a
To find a and b, we must know that a and b are located at y = ax^2 + bx + c.
We find that b is 4 and a is 1 by looking at the given quadratic function.
The answer is A. -4/2(1) because the question is looking for the correct steps to find the answer.
24x^3-40x^2. 45x-75
8x^2(3x-5). 15(3x-5)
(8x^2+15)(3x-5)
