Answer:
1: 4
2: 2
3: 8
Step-by-step explanation:
It is A.) or the top left answer.
For part one, this means that the y value (the second value) is -8, and since we know that y=3x-2, we can say that -8=3x-2.
Adding 2 to both sides using the addition property of equality, we get -6=3x. Next, dividing by 3 using the division property of equality, we get -2=x. Therefore, plugging -2 in the point, we get (-2,-8) as our point.
For the second point, we have 2 as the x value, so we can plug that into 3x-2 to get 3*(2)-2=6-2=4 as the y value, making the point (2,4)

#1 alright so if the ratio is 5:4 adding them together is 9 but we want 36 as the perimeter sooo
36/9=4
So multiply both the 5 and the 4 makes....
20:16
The 20 and 16 show the total side of the length Andy width so we need to divide them by two so...
(20/2):(16/2)=10:8 so the width would be 8
Check:10(2)+8(2)=20+16=36 yay on to the next one!
#2 ok let's say the length is x, that means the width would be x-5 so the perimeter of that would be 4x-10. Sooo...
4x-10=54 || 4x=54+10 || 4x=64 || x= 16
So the length is 16 while the width is 11. Let's check in case.
16(2)+11(2)=32+22=54 yup :D
186, start by multiplying 266 by 6 and youd get 1596, then subtract that from 2340 and youd get 744, then divide that by 4 and youd get 186.
