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
Answer:
D
Step-by-step explanation:
intercept is -4 and slope is rise over run which is 3/1 = 3
put into slope intercept form to achieve answer D
Answer:
B. m < 1 + m < 2 = 180; m < 2 + m < 3 = 180.
Step-by-step explanation:
m < 1 + m < 2 = 180 so m < 1 = 180 - m < 2
m < 2 + m < 3 = 180 so m < 3 = 180 - m^2.
So by the transitive property of equality m < 1 = m < 3.
It is 729
We get this by doing 3x3x3x3x3x3
