Answer:
18
Step-by-step explanation:
If 100% is 9 then you need to multiply by 2 to get 200% which is 18.
One number is 18 and the other is 22
(x,y)
sub points to see if we get true statemtn
(2,12)
x=2 and y=12
12-5=5(2)
7=10
false
no, (2,12) is not a point
(-2,-5)
x=-2
y=-5
-5-5=5(-2)
-10=-10
true
(-2,-5) is a soltuion
(-2,-5) is the only solution given that works
I can't directly tell you the answer, but I can help you for how to do it.
So every single time you want to find the rate of change (slope) label 2 points with x1, y1, x2 and y2. We can use the point-slope form to sind the slope:
y1-y2/x1-x2
And we just need to plug in the point to get the Y intercept.
When the x is 0, the y value will be the y-intercept.
The slope intercept form is: y=Mx+B. M stands for slope and B stand for y-intercept. Just plug the slope and y-intercept in and get the answer.
1- 1 2/5
2- 4 1/2
3- 1 1/8
4- 1 5/6
5- 12/17
