Problems 1. List the members of these sets:
(a) {x | x ER, x3 = x}
(b) {2x – 1 x 7,1 < x < 12}
(c) {x | x E Q, x2 = 2} (HINT: V2 and -V2 are not rational!)
2. What are these sets equal to?
(a) {x | X ER, 2+3 +1 = 2-3}
(b) {x | x ER, x = x}

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
