Hey!

Let's start by writing the problem:
2x+7=12x-6
Subtract 7 from both sides.
2x+7-7=12x-6-7
2x=12x-13
Subtact 12x from both sides.
2x-12x=12x-13-12x
-10x=-13
Divide both sides by -10.
\frac{-10x}{-10}=\frac{-13}{-10}
x=\frac{13}{10}

Let me know if you have any questions regarding this problem!
Thanks!

2x+7=12x-6  subtract 12x from both sides

-10x+7=-6  subtract 7 from both sides

-10x=-13  divide both sides by -10

x=13/10

x=1.3

If f(x)= -6x+6 then f^-1(x)=
drek231 [11]
Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".

\bf \stackrel{f(x)}{y}=-6x+6\qquad inverse\implies \boxed{x}=-6\boxed{y}+6
\\\\\\
x-6=-6y\implies \cfrac{x-6}{-6}=y\implies -\cfrac{x}{6}+1=\stackrel{f^{-1}(x)}{y}

What is the area of the composite figure? (use 3.14 for pi). Explain how you arrived at your answer.
Oksanka [162]

Answer:

20.28 cm^2

Step-by-step explanation:

First we have to find the diameter of the semi-circle, to do that we take the longest length on the bottom and subtract the lengths on top of the rectangle to get 4. We then multiply 4 * 3.14 (for pi) and half it because it is a semi circle, this gives us 6.28 for the semi circle, then we add the area of the rectangle at the bottom, 14 cm^2 and get 20.28 cm^2!
