Answer:
the answer is (-4, 5)
Step-by-step explanation:
Let's use elimination by addition / subtraction:
-6x - 2y = 14
6x + 7y = 11
-------------------
5y = 25, so y = 5.
Substituting 5 for y in the 2nd equation, we get:
6x + 7(5) = 11, or:
6x + 35 = 11, or
6x = -24, or x = -4.
Thus, the answer is (-4, 5). Please double check to ensure you have copied down both system of equations and answer correctly.
Check: Is (-4, 5) a solution to this system?
Subst. -4 for x and 5 for y in the first equation:
-3(-4) - (5) = 7
12 - 5 = 7 YES
Mato's rectangular prism's volume is
40
To find the volume of a Rectangular Prism it's:
Volume= Length x Width x Height
Draw a rectangular prism with the volume of 40.
Then just explain by showing how to solve for your prism's volume and then Mato's.

Answer: 10x - 5y = 40
Reason:
Why 5x - 10y = -12 is wrong (working):
5x - 10y = -12
-10y = -5x - 12
y = 0.5x + 1.2
(positive slope but not the correct y-intercept)
Why 10x - 5y = 40 is correct (working):
10x - 5y = 40
-5y = 40 - 10x
y = 2x - 8
(positive slope and correct y-intercept)
Why 5x + y = 50 is wrong (working):
5x + y = 50
y = -5x + 50
(negative slope and not the correct y-intercept)
Why x - 2y = 10 is wrong (working):
x - 2y = 10
-2y = -x + 10
y = 0.5x - 5
(positive slope but not the correct y-intercept)
Therefore, 10x - 5y = 40 is the answer
