Answer:
13
Step-by-step explanation:
if y = 4, then 4 + 9 = 13
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Okay so you would use PEMDAS (parentheses, exponents, multiply, divide, add, and subtract) so there are no parentheses so you do the exponents

then you do the rest so 100+36=136 and then 136-9=127 so the answer is 127
Answer:
Step-by-step explanation:
Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.
c first:
and
and
c - 8 = 272 s0
c = 280
For a:
and
and
-34a = 3 so

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.
