It shows a change in growth, and has a percentage rate that is positive, I .
Answer:
10/25
Step-by-step explanation:
2/5 = x/25
We need to multiply the bottom by 5 to get to 25
5*5 = 25
What we to the bottom, we do the the top
2/5 * 5/5 = 10/25
The answer is to the equation is b
Answer:
y=-2/3x +1
Slope = The change in y over the change in x so to do this you can use the two points To find the change in y to be -1-3=4 And the change in x to be 3 -(-3)=6 so you get -4/6 which can be simplified to -2/3 Then to find the next part find the y intercept which is y=1 at x=0
4a + 6b = 10
2a - 4b = 12...multiply by -2
----------------
4a + 6b = 10
-4a + 8b = - 24 (result of multiplying by -2)
------------------add
14b = - 14
b = -14/14
b = -1
2a - 4b = 12
2a - 4(-1) = 12
2a + 4 = 12
2a = 12 - 4
2a = 8
a = 8/2
a = 4
so 12a = 12(4) = 48 <==
