Are there choices listed? If not, then we can take the information given and translate it to an equation as follows: 40m = 400. Solve for m by dividing both sides by 40 and find that Carlos ran 10 miles.
Step-by-step explanation:
(0,0) (1,45) (2,90) (3, 135) (4, 180) etc, etc
Answer:
6x+3
Step-by-step explanation:
8x+7-2x-4
Combine like terms
8x -2x + 7-4
6x +3
The easiest way to do this is to realize this is a <em>weighted average</em> of the two points. (A weighted average is a linear combination where the coefficients add to one.)
(x,y) = (1-t)C + tD
where t is a real parameter. When t=0 we're at point C, when t=1 we're at point D. We're interested in t=1/4,
(x,y)= (3/4) C + (1/4) D
We're only asked for the x coordinate:
x = (3/4) (1) + (1/4) (-4) = 3/4 - 1 = - 1/4
Answer: 
6 to the second power is 36 divided by 2 is 18 plus 4 = 24
