Answer:

x = 7

Step-by-step explanation:

3x - (1/9)y = 18

*subsitute y as 27, because they are equal to each other*

3x - (1/9)(27) = 18

*multiply and simplify)

3x - (27/9) = 18

*isolate x*

3x - 3 = 18

3x = 21

<u>x = 7</u>

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?
PtichkaEL [24]

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

1000^{2015}

We have to find the number of digits ,

So,

1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}

Since we know that

10^n\text{ has n+1 number of digits }

so,

10^{6045}\text{ has 6046 number of digits }

Hence, there are 6046 digits will be written on expansion upto 2015th power.

jacquie hired a contractor to install a tile floor in her laundry room which measures 10.5 feet by 8 feet. the contractor inform
Agata [3.3K]
There are 3 types of cost for this problem: the cost for the area covered by the tiles, cost for hourly labor and the sales tax.

Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12

Total Cost = $564 + $45.12 = <em>$609.12</em>

So, the amount of the bill is incorrect.

What is the range of this absolute value function? a. -[infinity] &lt; y ≤ 0 b. 0 ≤ y &lt; [infinity] c. -[infinity] &lt; y ≤ 7
tigry1 [53]

If the equation of the absolute value function is f(x) = |x + 1| + 7, then the range of the function is -∞ < y ≤ 7

<h3>How to determine the range of the absolute value function?</h3>

<em>The question is incomplete, so I will provide a general explanation</em>

Assume that the absolute value function is given as:

f(x) = |x + 1| + 7

Set the absolute value to 0

f(x) ≥ 0 + 7

Evaluate

f(x) ≥ 7

This means that the smallest value of the function is 7

Hence, the range of the absolute value function is -∞ < y ≤ 7
