Answer:
D. 
and 
Step-by-step explanation:
The vertex of a function is controlled by the translations of the x and y value. Moving a vertex up and down is connected to the vertical position or the y-value. The y-value is the value that is added to the variable and is not squared.
Vertex form of a function is 
. In this case, k controls the vertical position of the vertex. If k is negative then the vertex will be moved down. So, if you want to move a vertex down by 5 units, then the k value must be -5.
Plug this into the formula to get the equation for k(x). This means that k(x) must equal 
.
Your answer is below (for y)
y=−23x+950
Your answer for x is
x=−y/23+950/23x
160 percent of 19 = 30.4 hope this helps :)
Divide the one by the other, and you get a value of 1299, meaning you could fit almost 1300<span> Earth's inside Jupiter. In short, the king of the planets is much, much, MUCH bigger than the planet we call home.</span>
