Answer:Hi, the correct answer is 
.
Step-by-step explanation:
As you are being asked for rate and the importat value is the number of calories consumed. We need to simplify the fraction 
. Then we simplify.
Note that 480 is divisible by 3 and 9 as well. 480/3 = 160 and 9/3 = 3. Therefore, 480/9 = 160/3.
Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
7*10=70 millimeters
1 cm=10 mm
Answer:
2 numbers that multiply to make -21 = 3 x (-7)
2 numbers that add up to -4 = 3 - 7
Step-by-step explanation:
2 numbers that multiply to make -21 = 3 x (-7) = -21
2 numbers that add up to -4 = 3 - 7 = -4
