Write a system of two linear equations in x and y that has the ordered pair solution (4,3). Choose the correct system below.
A.
- 2x + y = 5
x-2y = 13
B.
- 2x + y = -5
x-2y = -2
C.
- 2x + y = 6
2x + y = -9
D.
{
- 2x + y = -5
x-2y = 2

1/4 because there is 4 grades.

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.

answer: y=0 if that is what u r looking for
