Answer:
the answer is 11 1/2.
Step-by-step explanation:
I used a calculator
2x + 3y = 10 -> y = -2/3x + 10/3 it's a function
4x = 16 -> x =4 it's not a function
2x - 3 = 14 -> x = 8.5 it's not a function
3y = 18 -> y = 6 it's a function
2x = 6 -> x = 3 it's not a function
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

slope is 1/5
Step-by-step explanation:
Count how far right the point goes=1
count how far up the point goes =5
Answer:
Two options:
5,6, and 7
-1,0,and 1
Step-by-step explanation:
Three consecutive natural numbers can be represented as n, n+1, and n+2.
The product of the smaller two would be n(n+1). The less than 5 times the larger is 5(n+2)-5.
Set them equal and solve by factoring:
Set each factor equal to 0.
n-5==0 so n=5.
n+1=0 so n=-1.
This means the 3 consecutive numbers would be 5,6, and 7
OR
-1, 0 or 1.
