Answer:

When you are typing your question, on the bottom, there should be icons for bold, italic, and underline. The very last one is a paperclip looking icon. If you click on the paperclip, it will ask you to add a photo. If you're using a laptop/computer, then you need to save your picture in your files. Then just click on the picture you want to add.

Question 1 of 10
kvasek [131]

Given:

A parabola opens up or down and its vertex is at the point (h, v).

To find:

The equation of the parabola.

Solution:

A parabola opens up or down. It means it is a vertical parabola.

The vertex form of a vertical parabola is

y=a(x-h)^2+k             ...(i)

Where, a is constant and (h,k) is vertex.

The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

y=a(x-h)^2+v

The required equation of the parabola is y=a(x-h)^2+v.

Therefore, the correct option is A.

One number is 7 less than another. If 4 times the smaller number plus 2 times the larger number is 62, find the two numbers.
Nana76 [90]
X=Y-7

4X+2Y=62

4(Y-7)+2Y=62

4Y-28+2Y=62

6Y=62+28

6Y=90

Y=90/6

Y=15
Larger number^

X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62

32+30=62

62=62
