2x = 15 - 3x -- add 3x to both sides
5x = 15 -- divide both sides by 5
x = 3 -- simplest form
Here is the answer with my work !!
Answer: 11 people have a brother in the left circle, 6 people have neither in the center circle, and 9 people have a sister in the far right circle.
Answer: D. y = x^2
Step-by-step explanation:
Linear functions are functions in which the power of the unknown variable is 1 , that is the other of the unknown variable will be 1
A. y = x
This is a linear function because both x and y has 1 has their power
B. y = 2x
This is also linear
C. y = x + 2
This is also linear
D. y = x^2
This is not linear , although the power of y is 1 but the power of x is 2 , for it to be linear , the highest power of the unknown must be 1
