Answer:
Step-by-step explanation:
<u>Given system:</u>
Eliminate r to solve for s.
<u>To do so, double the first equation and then subtract the second one:</u>
<u>Subtract</u>
- 4s - (-s) = 104 - 4
- 5s = 100
- s = 100/5
- s = 20
Correct choice is (4) 20
Answer:
Step-by-step explanation:
y= 1/2x + −7/2
Answer:
f(x)+41 f(-10)=7
Step-by-step explanation:
6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5
