Answer:
B.) Communative
Step-by-step explanation:
The communitive property is when changing the order of the operands does not change the result. For this equation if you had it as 7 * 5 it would equal 35 and when it is 5 * 7 it would still equal 35.
I believe it is: 212
y2-y1 / x2-x1
549-125 / 5-3
212
Step-by-step explanation:
just look at the graphic : what value do we have on the cost side, when we have 1 pounds on the amount side ?
all the answer options specify a price per pound. that is why we only need to focus on the price for one pound.
we see in the graphic, that for 1 pound the price is $4.
just to make sure, we can also work with the directly specified point (0.5, 2), which means that 0.5 pounds cost $2.
and the function is clearly a straight line.
so, every point on the function has the same y/x ratio (slope).
therefore,
2/0.5 = 4
now, what point with x=1 has the same ratio ?
y/1 = 4
y = $4
perfect, the results are identical. so, $4 per pound is the correct answer.
Divide the top and bottom by the highest number that can divide into BOTH numbers.
The value is 21 Because three represents those to variables which both equal to 21.
