How many solutions exist for the system of equations below? 3x+y=18 3x+y=16

we have

-------> equation

solve for y

The slope

-------> equation

solve for y

The slope

The two slopes are the same, so the lines are parallel.

therefore

It's an inconsistent system of equations that has no solution.

the answer is

The system has no solution

answer: 2 litters juice bottle

half of a gallon is 50% of a full gallon 2 litters of juice is 52% of a full gallon

hope this ^_^

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.
