Factor the quadratic expression in the equation y = 2x2 + 8x - 154 and find the zeros of the equation. Then
Tema [17]

Answer:

zeros: -11 , 7

Line of symmetry: x = -2

Step-by-step explanation:

y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)

y = 0

x = - 11 or x = 7

line of symmetry: x = 1/2 (-11 + 7) = -2

2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162

vertex (h , k): h = -2 , k = -162

Line of symmetry: x = -2

VMariaS [17]

Answer:

75%

Step-by-step explanation:

First, take a look at the equation.

  4, 500(1.75)^t

4500 is the y-intercept, or the INITIAL VALUE, as given in the information.

Exponential Growth is shown when the percentage is added to 1. For example, in this case, it's 1+0.75, which equals 1.75.

Therefore, annually, it increases by 75%.
