I believe that it is 45 degrees. i could be wrong, so make sure to check!
Answer:
Value of z = 7
Value of y = 30
Step-by-step explanation:
We are given the following equations in the question:
We have to solve the given equation for y and z.
Equating the two equations we get,
Value of z = 7
Value of y = 30
Answer:
(15/2, -5/2)
Step-by-step explanation:
1. Sub x=5y+20 into 2x+2y=10 and simplify as shown below.
2(5y+20)+2y=10
10y+40+2y=10
12y+40=10
12y=-30
y=-30/12
y=-5/2
2. Sub in y=-5/2 into 2x+2y=10 to find x and simplify as shown below.
2x+2(-5/2)=10
2x-5=10
2x=15
x=15/2
The answer is one because the exact answer is 0.9788 and then they’re asking you to round
