Answer:

0.5(x + 3)
2(0.25x + 0.75)

Step-by-step explanation:

If you expand 0.5(x + 3) you get;

0.5x + 1.5

If you expand 2(0.25x + 0.75) you get;

0.5x + 1.5

What’s the inverse of <br> f(x) = -2 + 2/3x

saveliy_v [14]

So the steps to find the inverse are:

Change f(x) to y
Switch the positions of x and y
Solve for y
Change y to f^-1(x)

$f(x)=-2+ \frac{2}{3}x\\\\y=-2+ \frac{2}{3}x\\\\x=-2+ \frac{2}{3}y$

Now let's solve for y as such:

$x=-2+ \frac{2}{3}y \\\\x+2=\frac{2}{3}y\\\\\frac{3}{2} (x+2)=y\\\\\frac{3}{2}x+3=y\\\\\frac{3}{2}x+3=f^{-1}(x)$

<u>Your inverse is f^-1(x) = 3/2x + 3</u>

Point M is the midpoint of segment QR. If QM = 16 + x and MR = 2(x + 2), find the length of QM.

pav-90 [236]

Just add them
QM+MR=QR
16+x+2(x+2)=QR
16+x+2x+4=QR
20+3x=QR
