(b) In Los Angeles, a computer costs around 1 300 USD. The exchange rate is $1 = 0.74 USD.
Find the cost of the computer in dollars.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

answer:

c) the x-coordinate of the center of the circle increases by 3
