The vertex of this parabola is at (-3, -1). when the y-value is 0, the x-value is 4. what is the coefficient of the squared expression in the parabola's equation?

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k   where

Since the given information is (h, k) = (-3, -1)  and (x, y) = (4, 0), we can input those values into the vertex form and solve for "a":

0 = a[4 - (-3)]² + (-1)

0 = a(4 + 3)² - 1

0 = a(49) - 1

1 = 49a

24: 56

step-by-step explanation:

24 can be divided into 3 and 56 can be divided into 7, where as all the other ratios can't.
