Answer:
$26.31
Step-by-step explanation:
Since 3 is half of 6, 3 pairs of shoes would cost half the price.
So...
52.62/2=$26.31
<h3>
Solution:</h3>
A linear function is a straight line formed on a coordinate plane.
<u>To classify an equation as a linear function:</u>
- It must not have any exponent in the equation.
- If there is a fraction, the denominator of that fraction must not multiply by x.
If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.
<u>Option A - y = x³ + 1:</u>
- This equation has an exponent in the variable x. Hence, this is a non-linear function.
<u>Option B - 5x/6 = y - 4:</u>
- This equation has no exponents in the equation. Hence, this is a linear function and also our answer.
<u>Option C - y = 8x²</u>
- This equation has an exponent in the term 8x². Hence, this is a non-linear function.
<u>Option D - y = 1/5x</u>
- The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.
Hence, Option B is correct.

Answer:
cost per minute is 0.04
Step-by-step explanation:
Unit rates defined as the rates are expressed as a quantity of 1 such as 2 feet per second or 5 miles per hour they are called unit rates.
Given: Costs = $ 30 a month
In a month of may she used cellphone 12.5 hours.
First convert 12.5 hours in minute.
Use conversion: 1 hour = 60 minutes
then, 12.5 hours = 
to find the cost per minute.
by definition;
unit rate(cost per minute ) = 
cost per minute.
therefore, her cost per minute is 0.04
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
