If blueberries cost $4.00 per pound, how many pounds of blueberries can you buy for $1.00?

Masteriza [31]

If x is the number of berries you can buy with 1 dollar,

1 pound of blueberries = $4.00

x pound of berries = $1.00

Lets set up a proportion- because these are directly proportional- when there is more pounds of berries, it will cost more.

$\frac{1}{4.00} = \frac{x}{1.00}$

Cross multiply

4x=1

Divide both sides by 4 to isolate x

x=1/4 or $0.25

Which ordered pair is the y intercept of y=2x^2+3x-3?

rosijanka [135]

Answer:

I think it's A - (0,-3)

Step-by-step explanation:

x,y

(0,-3)

y-intercept equation for this problem:

$y=2x^{2}+3x-3$

Break it down to smaller parts:

$2(0)^{2} +3(0) = 0$

$0 - 3 = -3$

Rewriting it in a neater way:

=> $y = 2(0)^{2} +3(0) -3\\y=-3$

Therefore, answer A / the first choice is correct
