Answer:

x = $\frac{4\pi }{3}$

Step-by-step explanation:

given

cos(x - $\frac{\pi }{3}$ ) = - 1, then

x - $\frac{\pi }{3}$ = $cos^{-1}$ (- 1) = π

Add $\frac{\pi }{3}$ to both sides, hence

x = π + $\frac{\pi }{3}$ = $\frac{4\pi }{3}$

I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)

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
