Mathematics

Answer:

Step-by-step explanation:

Definition of absolute value:

|a| = a if a ≥ 0

|a| = -a if a < 0

Examples:

|2| = 2

|-2| = -(-2) = 2

|0.45| = 0.45

|-0.45| = -(-0.45) = 0.45

|1000| = 1000

|-1000| = 1000

Therefore

|1.7| = 1.7

Simplify the expression x^5 • x^7

iragen [17]

Answer:

$\Huge\boxed{\mathsf{\Rightarrow X^1^2}}$

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

With exponent rule.

<h3><u>SOLUTIONS:</u></h3>

First, use exponent rule.

<u><em>EXPONENT RULE:</em></u>

$\displaystyle \mathsf{\Rightarrow A^B*A^C=A^B^+^C}}$

$\displaystyle \mathsf{X^5^+^7}}$

Solve.

Add the numbers from left to right.

$\displaystyle \mathsf{7+5=\boxed{\mathsf{\Rightarrow 12}}}}$

$\Rightarrow \Large \boxed{\mathsf{X^1^2}}}$

So, the final answer is x¹².

Suppose you can work a total of no more than 38 hours each week at your two jobs. Housecleaning pays $7 per hour and your retail

MA_775_DIABLO [31]

Answer:

<u>The system of inequalities is:</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Amount of weekly hours you can work, no more than 38 hours (≤ 38)

Rate at housecleaning per hour = US$ 7

Rate at retail job per hour = US$ 8

Salary per week, at least US$ 280 (≥ 280)

2. Complete the system of linear inequalities to model this situation.

x = Number of hours per week worked at housecleaning job

y = Number of hours per week worked at retail job

Now, we have:

7x + 8y ≥ 280 (Total of salary of the two jobs should be at least US$ 280), where 7x is the salary received from housecleaning job and 8y is the salary received from retail job

x + y ≤ 38 (You can't work more than 38 hours per week)

Solve for n please, with work , thank you!

Paul [167]

$\huge \boxed{\mathfrak{Question} \downarrow}$

$\sf1 - 3 n \gt - 1 - 4 ( 2 n - 8 )$

Solve the inequality algebraically.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf1 - 3 n \gt - 1 - 4 ( 2 n - 8 )$

Use the distributive property to multiply -4 by 2n-8.

$\sf1-3n>-1-8n+32$

Add -1 and 32 to get 31.

$\sf1-3n>31-8n$

Add 8n to both sides.

$\sf1-3n+8n>31$

Combine -3n and 8n to get 5n.

$\sf1+5n>31$

Subtract 1 from both sides.

$\sf5n>31-1$

Subtract 1 from 31 to get 30.

$\sf5n>30$

Divide both sides by 5. As 5 > 0, the direction of the inequality remains the same.

$\sf \: n>\frac{30}{5} \\$

Divide 30 by 5 to get 6.

$\boxed{ \boxed{ \bf \: n>6 }}$
