5.15 for the first hour after subtracting 12.20(7.15)
Answer:
A. (0,7)
B. -1.25
C. Negative
D. I started at (0,7), then plotted the second point by moving the point down 5 and right 4.
Step-by-step explanation:
Look at the equation more carefully.
I hope this helps :)
Step-by-step explanation:
=> -3x - 4 = -5y - 8
=> 8 - 4 = 3x - 5y
=> 4 = 3x + (-5)y
=> 1 = (3x/4) + (-5y/4)
=> 1 = x/(4/3) + y/(-4/5)
Compare this with x/a + y/b = 1 where a and b are x & y intercepts.
Here,
x intercept = 4/3
y intercept = -4/5
