Answer:
it might be 48.9 but im not sure
Step-by-step explanation:
I'm not sure what your variables are, but I will try task 3 with you.
y=$500(in billions)
x= the number of years that have passed since 2009
percentage of decrease: 1 - % =
so your formula will look like this: y(1 - %)^x
so to find the slope we do y2- y1/ x2-x1
plug in the coordinates: (-6,4) (0,3)
3-4/ 0--6
3-4/0+6
= -1/6
Then using the formula of slop intercept form: y=mx+b........ use one of the coordinates to plug in
4= -1/6x+b...... multiply -6/1 on both sides of equation ( you do this so -1/6 and -6/1 can cancel out)
-24=b........ Use b to plug in y=mx+b---------> y= -1/6x-24
Answer:
864
Step-by-step explanation:
because if you take 8 percent of 900 72 x 12 you get 864.
