Answer:

Step-by-step explanation:

A.

R(x)=px=x(-45 x+1800)=-45 x²+1800 x

B.

C(x)=7000+100 x

C.

P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)

or P(x)=-45x²+1800 x-100 x-7000

or P(x)=-45 x²+1700 x-7000

Yes

remember that an odd power of a negative is negative
(-1)(-1)(-1)=(-1) tiat is negative
alsoo remember that ∛(ab)=(∛a)(∛b)

so
∛(-64)=(∛-1)(∛64)=(-1)(4)=-4

4 plates and 3 cups cost 20.70 dollars. 5 plates and 4 cups cost 26.40 dollars . each plates cost the same amount as the other p
Basile [38]
Here, we need to construct 2 linear equation.
Let x be the plate and y be the cup.
1) 4x + 3y = 20.70
2) 5x + 4y = 26.40

From equation 1, we solve for y.
3y = 20.70 - 4x
y = (20.70 - 4x) / 3

Substitute into equation 2.
5x + 4((20.70 - 4x) / 3) = 26.40
5x + 27.60 - 5.33x = 26.40
-0.33x = 26.40 - 27.60
-0.33x = -1.2
x = 3.64

We already get value of x. Now, calculate for value of y.
y = (20.70 - 4x) / 3
y = (20.70 - 4(3.64)) / 3
y = 2.05

The cost for 1 plate is 3.64 dollars and 1 cup is 2.05 dollars.
