Answer: B and C
Explanation:
x^2 + 3x - 18 = 0
(x + 6)(x - 3) = 0
Set x + 6 = 0 => x = -6
Set x - 3 = 0 => x = 3
1/2 + 1/4 + 1/4 + 2/3 = 5/3
mean = 5/3 ÷ 4 = 5/12
Answer:
w = -20
Step-by-step explanation:
8-3=5
-w/4=5
5*4=20
-w=20
-1/20=-20
w=-20
Answer:
[see below]
Step-by-step explanation:
A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.
The slope of 2x + 8y = 12 is
, and it's y-intercept is
.
Since parallel lines have the same slope but not the same y-intercept, I would use
.
Any equation that has -1/4 as the slope would work.
When graphed together, they show as a system with no solution.
Hope this helps.
