Solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.

(a) 20 - 4x = 12 - x + 8 - 3x

(b) 5x + 4x - 3 = 24 + 8x

(c) 5x + 6 = 2x + 6 + 3x - 15

i need asap! 27 points!

answer: no idea

step-by-step explanation: i just want points

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

if x = 1, then the answer is 3.5
