The discount is 36% off
Step-by-step explanation:
Hello!
1. -4x2 + 8x + 32
-4(x2 - 2x - 8)
-4(x2 + 2x - 4x - 8)
-4(x(x + 2) - 4(x + 2))
-4(x + 2)(x - 4)
Answer A.
2. 2x2 + 16x + 30
2(x2 + 8x + 15)
2(x2 + 5x + 3x + 15)
2(x(x + 5) + 3(x + 5))
2(x + 5)(x + 3)
Answer C.
As it has a positive leading coefficient the parabola will open upwards.
Also, as the y coordinate of the vertex is positive then the graph will not intersect the x axis at any point(s) , so there can be no real zeroes.
D is the correct choice
5(10)-y=54
50-y=54
-y=54-50
-y=4
y=4/-1
y=-4
hope its help you
