Given triangles are similar, so we setup a proportion

(140-x)/81 = x/9

solving gives x = 14
AC = 140-x = 140-14 = 126

The cost of tickets to a circus is expressed by the function y = 4x + 2, where

-BARSIC- [3]

Answer:

Step-by-step explanation:

This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.

Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.

You can also plug in 0 for x and get $4(0)+2=2$

Hope I helped :D

What is the length of CD? In this diagram, <br> ABC ~ EDC.

Alex777 [14]

Hey there!

Answer:

CD = 3.

Step-by-step explanation:

Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

$\frac{12-x}{18} =\frac{x}{6}$

Cross multiply:

$6(12-x) = 18x$

Distribute the '6':

$72-6x = 18x$

Combine like terms and simplify:

$72 = 24x$

$x = 3$

Therefore, the length of CD is 3.

Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.

Vikentia [17]

Step-by-step explanation:

$= \sqrt{x} .4 \sqrt{x}$

$= {x}^{ \frac{1}{2} } \times 4 {x}^{ \frac{1}{2} }$

$= 4 {x}^{ \frac{1}{2} + \frac{1}{2} }$

$= 4 {x}^{ \frac{2}{2} }$

$= 4 {x}^{1}$

$= 4x$
