Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
That is false.
y=7 is just a simplified way of writing y = 0 x 1 + 7
45 pieces of candy in total
45/6 would be 7.5
so each friend gets 7 pieces of candy with 3 pieces of candy left (7 x 6=42 )
Option D she ends up paying $7004.16 due to her bankruptcy
Answer:
y=-5x+5
Step-by-step explanation:
(0,5) y1 is 5 And x1 is 0. (1,10) y2 is 10 and x2 is 1. Y1-y2(5-10)=-5. X1-x2(0-1)=-1 slope is 5 because negatives cancel out. Y=5x+b. Now we find b which is the y intercept. Take one point and plug it into y=Mx+b. 5=-5(0)+b 5=0+b b=5 so y=-5x+5 is your answer
