What is f–1(8)??<br><br> Please select the best answer
notka56 [123]

Answer:

f^{-1}(8)=\frac{3}{2}

Step-by-step explanation:

Given f(x)=2x+5

We have to find f^{-1}(8)

In order to find f^{-1}(x) we have to make x as the subject of the formula

Let us assume f(x)=y

⇒2x+5=y

Subtracting both sides by 5

2x+5-5=y-5

2x=y-5

Dividing both sides by 2

\frac{2x}{2}=\frac{y-5}{2}

⇒x=\frac{y-5}{2}

Now substituting y with x

we have f^{-1}(x)=\frac{x-5}{2}

Now f^{-1}(8)=\frac{8-5}{2}

=\frac{3}{2}

So option (ii) is correct

In the figure, WY¯¯¯¯¯¯¯¯¯WY¯ and XZ¯¯¯¯¯¯¯¯XZ¯ intersect at point VV, the measure of ∠WVZ∠WVZ is (11x−19)°(11x−19)°, and the me
Zepler [3.9K]
Assuming a diagram similar to the one I've attached, ∠<em>YVZ</em> is a vertical angle to ∠<em>WVX</em>, which means they have an equal measure.  Additionally, ∠<em>WVZ</em> and ∠<em>WVX</em> form a linear pair, which means they are supplementary (sum to 180°).  That means we start out with the equation
(11x-19)+(8x+28)=180
We combine our like terms (the <em>x</em>'s get combined, then the constants get combined) and have:
19x+9=180
Cancel the 9 first by subtraction:
19x+9-9=180-9 \\ 19x=171
Cancel the 19 by division:
\frac{19x}{19}= \frac{171}{19}   \\ x=9
Since we know that our angle we're looking for, ∠<em>YVZ</em>, is the same measure as ∠<em>WVX</em>, we substitute 9 in for <em>x</em>:
8(9)+28=72+28=100°

-. If 5 + 4 = 9, does (5 + 4) = 3 = 9 = 4? Why or<br> why not?
Serjik [45]

Answer:No because if you add 5 plus 4 you will get nine but when u subtract 5 from four you will get 1 so no it would not get you any of those
