The value of r(x) at f(- 6) = 8.
We have the function r(x) = ![-\frac{2}{3} x + 4](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%204)
We have to find the value of r(x) at x = - 6.
<h3>If f(x) = 5x + 3, then find the value of f(-2).</h3>
Substitute x = - 2 in the value of f(x) -
f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.
According to question, we have -
f(x) = ![-\frac{2}{3} x + 4](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%204)
Substitute r = -6 in f(x), we have -
f(-6) = ![\frac{-2}{3} \times -6 + 4](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B3%7D%20%5Ctimes%20-6%20%2B%204)
f(-6) = - 2 x - 2 + 4
f(-6) = 4 + 4 = 8
Hence, the value of f(x) at f(- 6) = 8.

Simply set up a proportion. 1/3 = x/48. Cross multiply afterwards. 48 = 3x. Solve the equation. x = 16. By using proportions which is another form of a ratio you can easily find out that there are 16 adults at the school. Hope this helps :))
Answer:
Dont click the link its a virus, there is a bot going around answering peoples things trying to get them to download it.
Step-by-step explanation:
The answer is A, because if you take the coupon price (2.50) off of each number Ex: 3.00 it would be 3.00 - 2.50 = 0.50, keep doing that for each one and you will see they all match uo.
I don't have an idea of what the answer is to be honest.
Answer:
Step-by-step explanation:
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
