Answer:
9x-y = 5
Step-by-step explanation:
Equation of line in slope intercept form:
y-y1 = m*(x-x1), m=9, (x1,y1)=(4,31)
y-31 = 9*(x-4)
y-31 = 9x-36
9x-y = 36-31
9x-y = 5
Answer:
A
Step-by-step explanation:
-When the function moves to the right or left to the x axis, the number has to be in "( )"
-If it moves to the right, you SUBTRACT the amount of units
-It it moves to the left, you ADD the amount of units.
So in this case, it is moving to the right 12 units so it is 
Answer: m=6, m=-4
Step-by-step explanation:
To solve this proportion, we have to cross multiply.


Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

Combine like terms.

We can move all terms to one side and then solve for m.

We can actually factor this to:

We set each factor equal to 0 to find m.
m-6=0
m=6
m+4=0
m=-4
Answer:
46
Step-by-step explanation:
Since B is the midpoint of AC, the segments AB and BC must have equal length. This means that x + 13 = 2x + 3. Solving this, we see that x = 10. By substituting 10 for x, we see that the length of AB is 23, so the length of AC is 2*23, which is 46.
