Step-by-step explanation:
Using proportions, you are correct:
70/x = 100/50
cross multiply
100x = 3500
divide both sides by 100 to get your answer.

Answer:
Step-by-step explanation:
Domain is the set of all possible inputs (x) for the function f(x)
The range is the set of all possible values for that domain
This function is 4x + y = 3 which can be re-written as y = 3-4x
Plug in each of the domain values and you will get the range
For -2 : y = 3-4(-2) = 3 + 8 = 11
For 1: y = 3-4(1) = -1
For 5: y = 3-4(5) = -17
So range is {-17, -1, 11}
11n - 3 = 9 + 5n
solving:
11n-3=9+5n
+3 +3
11n=9+5n
-5n -5n
6n=9
/6 /6
n= 3/2 (check if correct)
