Answer:
2 h - 200 > 0
Step-by-step explanation:
The answer is B.red
the reason:
if x=2
-2 (2)+ 5y = 10
-4 +5y = 10
5y = 10+4
5y = 14
y = 2.8
now we have the point (2 . 2.8) which is absolutely on the line -2x + 5y = 10
when we look for it we see that it's on the line b which means line b is -2x + 5y = 10
t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
Answer:
- the y-intercept is (0,5)
- the slope is 2/3
Step-by-step explanation:
Answer:
elimination method
Step-by-step explanation:
2) 4y+4x=8;y+2x=4
4y+4x=8. ------(1)
y+2x=4 -------(2)
multiply equation (1) by 2 and (2) by 4 to eliminate x
8y+8x=16
4y+8x=4
