Let's prove each one:
A) y=x-3
x=0→y=0-3→y=-3=-3 ok
x=2→y=2-3→y=-1 different to 5 No
B) y=x+3
x=0→y=0+3→y=3 different to -3 No
C) y=4x-3
x=0→y=4(0)-3=0-3→y=-3=-3 ok
x=2→y=4(2)-3=8-3→y=5=5 ok
x=3→y=4(3)-3=12-3→y=9=9 ok
x=4→y=4(4)-3=16-3→y=13=13 ok
D) y=4x+3
x=0→y=4(0)+3=0+3→y=3 different to -3 No
Answer: Option C) y=4x-3
3 boxes times 40 = 120 + 3 = 143
or 3 boxes times 43 = 129
Answer:
yes
Step-by-step explanation:
The answer is A
5 x 129.95 = 649.75
649.75 + 76.20 = 725.95
Step-by-step explanation:
-5x - 5y + 4x - (2y + 3)
= - 5x + 4x - 5y - (2y + 3)
= - x - 5y - 2y - 3
= - x - 7y - 3 ( Answer )
