Answer:

Recall that the parabola

y^2 = 4px

has its

focus at (p,0)

directrix at x = -p

vertex is midway between the focus and the directrix, at (-5,-5)

So, here we clearly have p = 2

So the equations is

(y+5)^2 = 8(x+5)^2

NEED HELP PLZ FOR INTERIM TEST 2 x+4(x-1)=2+4x

lesya692 [45]

2x+4(x-1)=2+4x [First, you would distribute the 4 into the x and -1]

2x+4x-4=2+4x [Then combine like terms(2x+4x)]

6x-4=2+4x [Next, subtract common numbers (6x-4x)]

2x-4=2 [Then you would combine like terms (2+4)]

2x=6 [Finally, divide the 2x by 6]

x=3

Hope this helped!

Solve equation for n

balu736 [363]

Simplify 2/3 + n + 6 to n + 20/3

n + 20/3 = 3/4

Subtract 20/3 from both sides

n = 3/4 - 20/3

Simplify 3/4 - 20/3 to - 71/12

n = -71/12

Find the unit rate for 75% high-fiber chimp food to 25% high -protein chimp food

sammy [17]

Answer: The answer is 3.

Step-by-step explanation: We are given to find the unit rate for 75% high-fibre chimp food to 25% high -protein chimp food.

For that, we need to divide the quantity of fibre in food by the quantity of protein present in the food.

Fibre present in the food is given by

$f_f=75\%=\dfrac{75}{100}=\dfrac{3}{4}.$

And protein present in the food is

$f_p=25\%=\dfrac{25}{100}=\dfrac{1}{4}.$

Therefore, the unit rate of high-fibre chimp food to high-protein chimp food is

$U=\dfrac{\frac{3}{4}}{\dfrac{1}{4}}=3.$

Thus, the answer is 3.
