Answer:
No
Step-by-step explanation:
Write the ratios of erasers to cost (dropping the dollar sign) as fractions:
(number of erasers)/(price): 2/1 and 10/4
The question is if the ratios 2/1 and 10/4 are equivalent.
2/1 = 2
10/4 = 2.5
A proportion is setting two ratios equal. Here, one ratio equals 2, and one ratio equals 2.5.
Since the ratios are not equivalent, the relation is not proportional.
Answer:
y = (-5/12)x - 1
Step-by-step explanation:
The fastest way in which to express -5x-12y=12 in slope-intercept form is to solve -5x-12y=12 for y:
Add 5x to both sides, obtaining -12y = 12 + 5x.
Next, divide both sides by -12, obtaining y = -1 - (5/12)x, or y = (-5/12)x - 1.
2(2/5) divided 2(-1/5)
we do PEMDAS meaning parenthesis first
2(2/5) = 4/5(calculator)
or
2/1x2/5=4/5
now
2/1x-1/5=-2/5
now we do division
4/5/-2/5 we get -2
-2
