Musya8 [376]

Answer:

3000 is your answer

Step-by-step explanation:

Rebecca drove 44 1/3 miles in 1 1/3 hours. What is the unit rate for miles per hour?

saul85 [17]

$unit\ rate=\frac{distance}{time}\\\\
distance=44\frac{1}{3} miles\\
time=1\frac{1}{3}hour\\\\
unit\ rate=\frac{44\frac{1}{3}}{1\frac{1}{3}}=\ \ \ | make\ improper\ fractions\\
\frac{\frac{133}{3}}{\frac{4}{3}}=\frac{133}{3}*\frac{3}{4}=\frac{133}{4}=33\frac{1}{4}\\\\
unit\ rate= 33\frac{1}{4}\frac{miles}{hour}

What is the inverse of the function f(x) = 2x – 10?

Gala2k [10]

$\bf f(x)=\boxed{y}=2\boxed{x}-10\qquad inverse\implies =\boxed{x}=2\boxed{y}-10\impliedby f^{-1}
\\\\\\
x+10=2y\implies \cfrac{x+10}{2}=y\implies \cfrac{x}{2}+\cfrac{10}{2}=y
\\\\\\
\cfrac{x}{2}+5=y=f^{-1}(x)$

How to solve x=5 grafting

iVinArrow [24]

So this one is pretty easy actually when x= a number you automatically know it'll be a vertical line cutting through the x axis. So for this problem (x=5) the line will be vertical and cut through the x axis. Hope this helps!
