What is the equation written in vertex form of a parabola with a vertex of (–1, 8) that passes through (1, 0)?

Archy [21]

Answer:

y = -2(x + 1)^2 + 8

Step-by-step explanation:

The equation of a parabola can be written in the form;

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

where a is the multiplier (h,k) is the vertex

so h = -1 and k = 8

Plug in these values

y = a(x + 1)^2 + 8

So to get the value of a, we use the point where the parabola passes through which is the point (1,0)

Simply substitute the values of x and y

0 = a(1 + 1)^2 + 8

0 = a(2)^2 + 8

-8 = 4a

a = -8/4

a = -2

So therefore the equation of the parabola is ;

y = -2(x + 1)^2 + 8

What is the slope of y = 4 -2x?

erastovalidia [21]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have

$y=4-2x=-2x+4$

Therefore the slope is equal to -2.

Rickey has fraction 7/8 of a cup of cereal in a bowl. He then gave two fraction 1/4 cups of cereal from his bowl to his little s

Zinaida [17]

5/8 would be the answer..

7/8-1/4=(7 × 4) - (1 × 8)8 × 4=20/ 32=20 ÷ 432 ÷ 4=5/8
