Answer:
X= -50
Step-by-step explanation:
Remove the parenthesis
multiply both sides by two
x - 6 = -56
Move the 6 to the other side
x = -56 + 6
x = -50
Answer:
Step-by-step explanation:
I used logic and took the easy way around this as opposed to the long, drawn-out algebraic way. I noticed right off that at x = -3 and x = -1 the y values were the same. In the middle of those two x-values is -2, which is the vertex of the parabola with coordinates (-2, 4). That's the h and k in the formula I'm going to use. Then I picked a point from the table to use as my x and y in the formula I'm going to use. I chose (0, 3) because it's easy. The formula for a quadratic is

and I have everything I need to solve for a. Filling in my h, k, x, and y:
and
and
-1 = 4a so

In work/vertex form the equation for the quadratic is

In standard form it's:

Answer:
Step-by-step explanation: square root both numbers so 55 square root is 7.41 and he square root of 16 is 4 now divide them so 7.41 divided by 4 = to 1.85 there fore 1.85 is ur answer
