Answer:
B, C
Step-by-step explanation:
I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.
Two different x's can have the same y, but two different y's cannot have the same x.
In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.
This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.

3y+1=4y-6
1+6=4y-3y
y=7
2+6x=1-x
6x+x=1-2
7x=-1
x= -1/7
5y+4=4y+5
5y-4y=5-4
y=1

Explanation = 31900-22000/22000 • 100 = 45%
Step-by-step explanation:
The ratio and proportion is the mathematical concept that can explain the correlation between the size of a dog and the amount of food it eats. For example dogs weighing 3 to 7 kg should consume 67 to 112 grams of food per day, that is, the amount of food must be proportional to the weight of the dog.
The ratio and proportion are interconnected concepts that allow the understanding of comparison between quantities.
