thus, the best car is car B,because it can tavel 29 miles with only one gallon,andcar A can only travel 28 miles with one gallon.
Answer:
a=245 s=315
Step: Solve a+s=560 for a:
a+s=560
a+s=560(Add -s to both sides)
a=−s+560
Step: Substitute −s+560 for a in 8a+3s=2905:
8a+3s=2905
8(−s+560)+3s=2905
−5s+4480=2905(Simplify both sides of the equation)
−5s+4480=2905(Add -4480 to both sides)
−5s=−1575
−5s=−1575(Divide both sides by -5)
s=315
Step: Substitute 315 for s in a=−s+560:
a=−s+560
a=−315+560
a=245
The y intercept is when x = 0 so it is:-
8(0) + y = 8
0 + y = 8
y = 6 <------- y-interdept
x intercept is when y = 0 so:-
8x + 0 = 8
x = 1 <-------- x intercept
Answer:
there were no inequalities to choose from but I believe the answer is y ≤ 4x
