Alicia cashed her paycheck and used half her earnings to take three friends out to dinner. She spent $42.15 and she brought home

Phoenix [80]

If you would like to write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck, you can calculate this using the following steps:

X ... the amount of Alicia's paycheck

X/2 - $42.15 >= $20
X/2 >= $20 + $42.15
X/2 >= $62.15 /*2
X >= $62.15 * 2
X >= $124.3

The correct result would be <span>X >= $124.3</span>.

BONUS, Factor 1 - 64x^3 completely,

kvv77 [185]

Rewrite then factor as a difference of cubes:

1 - 64<em>x</em>³ = 1³ - (4<em>x</em>)³

= (1 - 4<em>x</em>) (1² + 4<em>x</em> + (4<em>x</em>)²)

= (1 - 4<em>x</em>) (1 + 4<em>x</em> + 16<em>x</em>²)

3. Suppose U= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set and Q = {3.6.9}. What is Q?

Dimas [21]

Answer:

Suppose U={1,2,3,4,5,6,7,8,9,10} is the universal set and M={7,8,9,10}. What is M'?

A. {1,2,3,4,5,6}

B. {1,2,3,4,5,6,7,8,9,10}

C. cannot be determined

D. {7,8,9,10}

My answer is D.

Step-by-step explanation:

M' means the complement of M.

M' will encompass all the elements in the universal set but NOT in the set M.

Which are correct representation of the inequality minus 32X -5 less than 52 minus X select two options

Murljashka [212]

Answer:

The value of X is more than equal to -1.83.

Step-by-step explanation:

We need to find the correct representation of the inequality 'minus 32X -5 less than 52 minus X'

LHS of the inequality will be : -32x-5

RHS of the inequality will be : (52-X)

So,

$-32X-5\leq 52-X$

Adding X both sides

$-32X-5+X\leq 52-X+X\\\\-31X-5\leq 52$

Adding 5 to both sides,

$-31X-5+5\leq 52+5\\\\-31X\leq 57$

Dividing both sides by -31.

$X\geq \dfrac{-57}{31}\\\\X\geq -1.83$

So, the value of X is more than equal to -1.83.
