Answer:

D:   {9, 21, 33}

Step-by-step explanation:

Ken worked 2, 8 and 14 hours on 3 separate days.

For working 2 hours, his earnings were f(2) = 2(2) + 5, or 9;

For working 8 hours, his earnings were f(28) = 2(8) + 5, or 21; and

For working 14 hours, his earnings were f(14) = 2(14) + 5, or 33

Thus, the range of this function for the days given is {9, 21, 33} (Answer D)

Which shows a difference of squares?
d1i1m1o1n [39]

Answer:

The equations shows a difference of squares are:

<u>10y²- 4x²</u>   $   <u>6y²- x²</u>

Step-by-step explanation:

the difference of two squares is a squared number subtracted from another squared number, it has the general from Ax² - By²

We will check the options to find which shows a difference of squares.

1) 10y²- 4x²

The expression is similar to the general form, so the equation represents a difference of squares.

It can be factored as (√10 y + 2x )( √10 y - 2x)

2) 6y²- x²

The expression is similar to the general form, so the equation represents a difference of squares.

It can be factored as (√6y + x )( √6y - x)

3) 8x²−40x+25

The expression is not similar to the general form, so the equation does not represent a difference of squares.

4) 64x²-48x+9

The expression is not similar to the general form, so the equation does not represent a difference of squares.

The scale on a map shows that 200 miles is represented by 5 inches on a map. Which proportion can be used to find the distance
Ivenika [448]

<em>Answer:</em>

<em>A proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps: </em>

<em> </em>

<em>200 miles ... 5 inches </em>

<em>50 miles ... x inch = ? </em>

<em> </em>

<em>200 * x = 5 * 50 </em>

<em>x = 5 * 50 / 200 </em>

<em>x = 1.25 inch </em>

<em> </em>

<em>The correct result would be x = 5 * 50 / 200.</em>
