Is (-5,-5) a soulution of y is greater then or equal to y> -2x+4

No

Step-by-step explanation:

To determine if (- 5, - 5) is a solution

Substitute x = - 5 into the inequality and compare answer to y

- 2(- 5) + 4 = 10 + 4 = 14 > - 5 ← the y- coordinate

Thus (- 5, - 5) is not a solution to the inequality

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.
