Answer:
An hour
Step-by-step explanation:
assuming the speed adds the half hour, three times the speed would take out an hour and a half (going by half hour marks)
Answer:
blue = 4
red = 8
green = 2
yellow = .75 or 3/4
Step-by-step explanation:
4 X 4 X 4 X 4 = 256
8 X 8 = 64
2 X 2 X 2 X 2 = 16
.75 X .75 = .5625 or 9/16

Answer:
1st and 3rd choices
Step-by-step explanation:
1st:
The graph follows the y=mx+b pattern, which if fits will always be a straight line.
This expression will be used throughout to explain answers.
3rd:
The y-intercept, or b, is -2. In the y-intercept, the x value is 0, so a point in the line is (0, -2).
The rest:
The 2nd is wrong because the y-intercept is -2. The line is two units below the origin when the x value is zero.
The 4th is wrong, because the slope, m, is 1/3, which is less than 3.
The 5th is wrong, because as explained in the 3rd choice, the y-intercept is -2, not 2.
