Factor out common terms in the first two terms, then in the last two terms
4x^2(5x - 3) + 3(5x - 3)
Factor out the common term 5x - 3
<u>= (5x - 3)(4x^2 + 3)</u>

Answer:
74%
Step-by-step explanation:
We have been given that the Average cost of a long distance call in the USA was 31 cents per minute in 1978 and 8 cents in 2008.
We will use percent decrease formula to solve our given problem.






Therefore, there is an approximate 74% decrease in cost per minute for the long distance call from 1978 to 2008.
Answer:
Step-by-step explanation:
the first graph has points (-1, -1) and (2, -2)
slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3
the second graph has points (0, -3) and (2, 0)
slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2
for the table
x. y
-3. 4
0. 1
slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1
