4.8 + 2.2w − 1.4w + 2.4
Lostsunrise [7]

Answer:

7.2 + 0.8w

Step-by-step explanation:

combine like terms. Like terms have same variable with same power.

2.2w and (-1.4w) are like terms & 4.8 and 2.4 are like terms.

4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w

                                      = 7.2 + 0.8w

An object is launched from a platform. It's height (in meters), x seconds after the launch, is modeled by: h(x)=-5(x-4)^2+180. W
Kipish [7]

The height of the object at the time of launch is 100 meters.

To find this, we simply have to put 0 in for x, as this is when there has been no time (at launch)

h(x)=-5(x-4)^2+180

h(0)=-5(0-4)^2+180

h(0)=-5(-4)^2+180

h(0)=-5(16)+180

h(0)=-80+180

h(0) = 100
