Answer:
The solution to the system of equations is:
The graph is attached below.
Step-by-step explanation:
Given the system of equations


Let us solve the system of equations using the elimination method

Arrange equation variables for elimination

Multiply y + 2x = 5 by 2: 2y + 4x = 10

subtracting the equations




solve 6x = 18 for x

Divide both sides by 6

simplify

For 2y - 2x = -8 plug in x = 3


Add 6 to both sides

Simplify

Divide both sides by 2

Simplify

Therefore, the solution to the system of equations is:
The graph is attached below.
Answer:
a = 33 degrees
Step-by-step explanation:
Note that 57 degrees and Angle a are complementary: they add up to 90 degrees.
Thus, a = 90 degrees less 57 degrees = 33 degrees
Answer:
192 cm^3
Step-by-step explanation:
Volume for rectangular prism is V=l*w*h
V=8*4*6=32*6=192
So volume is 192 cm^3
