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)
Answer:
2(x - 3)
Step-by-step explanation:
2(3 – x) – 12 + 4x
6 - 2x - 12 + 4x
2x - 6
2(x - 3)
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.
<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>
