Answer:
Step-by-step explanation:
the sum of 5x+20= 5(x+4)
and the opposite of 20 is negtive 20
If it is a combination of 2 then there is only 1 but if it is a combination of 1 then there is 2, hope this help!!
Answer: 8
Step-by-step explanation:
.32 x 25 = 8

Answer: c. 8(y-6) = (x-2)^2</h3>
Explanation:
The directrix is horizontal, so the axis of symmetry is vertical. We'll have an x^2 term. The vertical distance from y = 4 to y = 8 is 4 units. Cut this in half to get 2, which is the focal distance p = 2.
The point (2,4) is directly below (2,8), and the point is on the directrix. The midpoint between (2,4) and (2,8) is (2,6). This is the vertex.
(h,k) = (2,6)
4p(y-k) = (x-h)^2
4*2(y-6) = (x-2)^2
8(y-6) = (x-2)^2
