Answer:
1/30 of an hour
Step-by-step explanation:
12 out of 50 are over 6 feet (12/50)
Therefore 38 are under 6 feet (38/50)
Answer:
c+b / a
option 4
Step-by-step explanation:
ax - b = c
add b to both sides
ax = c + b
divide a on both sides
x = c+b / a

Work backwards from vertex form. Vertex form of a quadratic equation/parabola is the following:
f(x) = a(x - h)² + k, where (h, k) is the vertex.
f(x) = a(x - 6)² - 9
Now, plug in the point that you're given to SOLVE FOR A. Remember that f(x) is just another way of writing y.
8 = a(1)² - 9
8 = a - 9
a = 17
So, plug in a = 17 into the equation.
<span>f(x) = 17(x - 6)² - 9 ←← your answer.
