If f(x) = 5 + 4(x - 4)?,
what is f(7)?

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

f=x−528x−112

true

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
