Answer:
x = y
Step-by-step explanation:
x/3 + x/6 = 7/2
2x + x = 21
3x = 21
(divide 3 on both sides)
x = 7
Answer:
Option B and C are correct.

are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points
and 
then slope is:
or we can write this as:
Δy = 
Δx = 
⇒
Therefore, the expression which are incorrect for slope are;


Answer:
B. y=1/2+2
Step-by-step explanation:
since parallel lines always have the same slope, the only two possible answers could be B and C. in order to find if one of those goes through point (-2,1), we have to set up an equation to find the base:
1=1/2(-2)+b
1=-1+b
2=b
We can plug in the base with the slope for the equation and the new equation would be y=1/2x+2
Step-by-step explanation:
2x + 5 = I / 2 ×16
2x=3
x=3/2
