Answer:
1/8
Step-by-step explanation:
-5/8+3/4 =( -20+24)/32 = 4/32
4/32= 1/8
1/4 + 5/12 = 3/12 + 5/12= 8/12 = 2/3
You must get the denominators the same so you multiply both 1 and 4 and you get 3/12. Then you add the two fractions and simplify it into 2/3
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:
20 units or 4.8
