Question

If h(t) = -4t + 40, what is t if h(t)=20?

Answer 1

t = 5

Explanation:

If h(t) is = to -4t + 40 and is = to 20, then you can set these two equations equal to each other

So now we are here:

20 = -4t + 40

-20 = -4t Subtract 40 from both sides of the equation

5 = t Divide -4 from both sides of the equation

Answer 2

`t=5`

Explanation:

So we know that:

`h(t)=-4t+40`

And we want to figure out t such that h(t)=20.

So, substitute 20 for h(t):

`20=-4t+40`

Now, solve for t. Subtract 40 from both sides:

`-20=-4t`

Divide both sides by -4:

`t=5`

And we're done!
