Answer:
x=-5, y=5 or (-5,5)
Step-by-step explanation:
We can do elimination with this
this means we should first multiply -5x-4y=5 by 2
this would make it -10x-8y=10
we can now subtract this from the original equation
-8x-8y=0 - (-10x-8y=10)
the ys would cancel out
so this would equal
2x=-10
x=-5
now we can plug this back into the equation to find y
-8(-5)-8y=0
40-8y=0
-8y=-40
y=5
Answer:
The answer would be 28.
Step-by-step explanation:
Cuz, 10-2=8
8+20=28
So the answer is 28, Hope this helps:)
Answer:
228 in³
Step-by-step explanation:
<u>Volume of a trapezoidal prism</u>
<u>Finding Base Area (on the side here)</u>
- A = 1/2 x (a + b) x h
- A = 1/2 x (12 + 7) x 6
- A = 3 x 19
- A = 57 in²
<u>Volume</u>
- V = A x h
- V = 57 x 4
- V = 228 in³
I think the correct answer from the choices listed above is the second option. Solving a 6 order system <span>would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.</span>
