Arubber ball is dropped from a height of 128 feet. after each bounce, it rebounds one fourth of the distance it fell. how far does the ball fall on its third fall?

8ft

Step-by-step explanation:

The drop is 128 ft

The first bounce is 1/4 the drop (2nd fall)

1/4(128) = 32 ft

The second bounce is 1/4 of the first bounce  (This would be considered the third fall)

1/4 (32) = 8 ft

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
