Answer: you are correct the correct answer is A
Oh how fun, functions!! You substitute f(-2) into your starting function so it will look like this:
f(x)=2(5x+7)
f(x)=10x+14
f(-2)=10(-2)+14
f(-2)=(-20)+14
f(-2)=(-6)
divide by negative 2 on each side to find f:
f=3
Hope this helped!!
Answer:
The y coordinates are the same since they are both at y= 4
Step-by-step explanation:
The solution to the problem is as follows:
We have 2+.8(2) + .8(.8(2)) + .8(.8(.8(2))) + ... =
2( .8^0 + .8^1 + .8^2 + .8^3 + ... ) =
2(.8^n -1) / (.8-1) . As n-->infinity, .8^n-->0 giving us
<span>2(-1)/(-.2) = 2(5) = 10 meters.

Answer:
A: 7
B: 8
C: 6
Step-by-step explanation:
You have to try to find the the same greatest factor of both of the numbers.
Since both of the numbers are divisible by 7 the number of groups equals 7.
So you divide the number of girls, which is 56, by 7, the number of girls in each group is 8.
Then you divide the number of boys, which is 42, by 7, the number of boys in each group is 6.
