so this is how i was taught the inverse function. f(x) is basicly the same thing as saying y
so y=x over x+3
you switch the top x with y so it turns in to x=y over x+3
the problem should tell you what x equals so substitute x with the number it equals and then solve
here is an example f(x)=x over x+3 and x=14
x=y over x+3
14=y over 14+3
the inverse inverse function would probably be just solve the equation so just substitute the number they give you for x in for x
Answer:
6
Step-by-step explanation:
It appears you have vertical angles. The rule with angles is that no matter what, vertical angles are always congruent (or the same). This means you would have to set up the equation to solve for "b" as:
70 - 2b = 28 + 5b
You could solve this manually, but Desmos graphing calculator is faster. Simply type this in and replace b with x and it will give you the answer, which is 6. Hope this helps!
Answer:
1 - 9/7n
Explanation:
1/7 - 3(3/7n - 2/7)
<em>distribute</em><em> </em><em>the</em><em> </em><em>3</em><em> </em><em>with</em><em> </em><em>the</em><em> </em><em>2</em><em> </em><em>fractions</em><em> </em><em>inside</em><em> </em><em>the</em><em> </em><em>parenthesis</em>
1/7 - 9/7n + 6/7
<em>add</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>(</em><em>1</em><em>/</em><em>7</em><em> </em><em>+</em><em> </em><em>6</em><em>/</em><em>7</em><em>)</em>
7/7 - 9/7n
<em>or</em>
1 - 9/7n
