7/3 = 1/x
7x = 3
x = 3/7
3/7 of a cup of red paint should be added to 1 cup of white paint
Answer:
C -1/2
Step-by-step explanation:
First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.

f(x) = -2x + 1 works with (-1, 3)
f(x) = -2x^2 - 4x + 1 works with (0,1)
f(x) = 2sqrt(x + 2) + 1 works with (2, 5)
In order to find each of these, you need to try the ordered pairs in the equation and look for them to come out as true statements. Below is the work of trying each one.
(-1, 3)
f(x) = -2x + 1
3 = -2(-1) + 1
3 = 2 + 1
3 = 3 (TRUE)
(0,1)
f(x) = -2x^2 - 4x + 1
1 = -2(0)^2 - 4(0) + 1
1 = 0 + 0 + 1
1 = 1 (TRUE)
(2, 5)
f(x) = 2sqrt(x + 2) + 1
5 = 2sqrt(2 + 2) + 1
5 = 2sqrt(4) + 1
5 = 2(2) + 1
5 = 4 + 1
5 = 5 (TRUE)
