Answer:

  D)  (10,-8)

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  f(x) = a(x -h)^2 +k . . . . . . for vertex (h, k) and scale factor "a"

Matching this pattern to the given equation, we see that ...

  a = -5, h = 10, k = -8

so the vertex is (h, k) = (10, -8) . . . . . matches choice D

We need to multiply

-2y(y+3)

We need to use the distributive property to expand this:

a(b+c)=ab+ac

Let's multiply it out using this property, to get our answer:

\begin{gathered} -2y(y+3) \\ =-2y(y)+(-2y)(3) \\ =-2y^2-6y \end{gathered}

What is the value of x in the equation 8x-2y=48, when y=4
Oksanka [162]
8x - 2y = 48,  y =4

8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x  = 56
x = 56/8 = 7

x = 7

Korvikt [17]
You haven’t provided any option, however I think I can still help.

You can solve 4(3-6). You first deal with he parenthesis, and get 4(-3). This means that your expression is equivalent to -12.


Hope this helps :)
