To determine the inverse function, first, we set the following equation:

y=-10+8x\text{.}

Now, we solve the above equation for x:

\begin{gathered} y+10=8x, \\ \frac{y+10}{8}=x\text{.} \end{gathered}

Exchanging x and y, we get:

y=\frac{x+10}{8}\text{.}

Finally, we substitute y by

f^{-1}(x)

and get:

f^{-1}(x)=\frac{x+10}{8}\text{.}

Answer:

f^{-1}(x)=\frac{x+10}{8}\text{.}

Given the vectors u = <5,-1> and v = <1,12>, find -7u-3v. *
zepelin [54]

You multiply vectors and scalar simply by multiplying each component by that scalar:

-7u = \langle-35,7\rangle,\quad -3v=\langle -3,-36\rangle

Finally, you sum two vectors by summing the correspondent coordinates:

-7u-3v = \langle-35,7\rangle+\langle -3,-36\rangle = \langle-38,-29\rangle

A family purchased basketball tickets online. The total cost, c, in dollars, of t tickets can be found using the function below.
Reptile [31]
Solution:
C=32.50t+8.50
236=32.50t+8.50
236-8.50=32.50t
227.50=32.50t
227.50/32.50=32.50t/32.50
t=7

The family bought 7 tickets.
