Answer:
You can't she do the same thing to me like I just be answering question for points and they mostly be correct and she just be deleting the questions like crazy.
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
My guess would probably be A = 21
Answer:
(- 1, 9 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 6 → (1)
y = 9 → (2)
Substitute y = 9 into (1) and solve for x
9 = - 3x + 6 ( subtract 6 from both sides )
3 = - 3x ( divide both sides by - 3 )
- 1 = x
Solution is (- 1, 9 )
It is C. 498.83 units cubed.
Hope I helped? ^ω^
