As, synthetic division by -4 gives remainder 0. Hence, Option B is correct. -4 is a root of 
As, x+4=0 gives x=-4.
So, option C is correct,
(x+4) is factor of
Option E is correct
Answer:
Total cost of Mark's board is $3.75.
Step-by-step explanation:
We are given the following in the question:
Length of wooden board =
Unit cost of board = $0.50 per foot
Total cost of board =
Thus, total cost of Mark's board is $3.75.
Answer:
If we don't what you're solving for we can't solve for x
Step-by-step explanation:
If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope . To do that we are going to use the slope formula: .
From our two points we can infer that , , , . Lets replace those values in the slope formula:
Now that we have our slope, we can use the slope-intercept formula:
We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is .
