A rock is launched from a cannon. Its height, h(x), can be represented by
quadratic function in terms of time, x, in
seconds.
After 1 second, the rock is 148 feet in
the air, after 2 seconds, it is 272 feet in
the air.
PLEASEE HELPPP!

b) well because you get well

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
