Aramp with a constant incline is made to connect a driveway to a front door. at a point 4 feet from the driveway, the height of the ramp is 12 inches. at a point 6 feet from the driveway, the height of the ramp is 18 inches. what is the rate of change of the ramp’s incline? inch up per foot across inch up per foot across 2 inches up per foot across 3 inches up per foot across

3 inches per foot.

Step-by-step explanation:

Given: A ramp with a constant incline is made to connect a driveway to a front door.

At a point 4 feet from the driveway , the height  of the ramp is 12 inches.

At a point 6 feet from the driveway  , the height   of the ramp is 18 inches.

The rate of change of the ramp’s incline is given by :-

Hence, the rate of change of the ramp’s incline is 3 inches per foot.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
