Constant rates are used to illustrate linear functions.
- The average rate of change is $9.0 per hour
- The function that models the table is:

- The amount earned in 7.5 hours is $67.5
<u>(a) The average rate of change</u>
This is calculated using:

So, we have:



Hence, the average rate of change is $9.0 per hour
<u>(b) A function that models the table of values</u>
Let x represent hours, and y represent the earnings.
So, we have:

Where:
m =Rate = 9.0
So, we have:

Expand


Represent as a function

Hence, the function that models the table is: 
<u>(c) Amount earned for 7.5 hours</u>
This means that x = 7.5
So, we have:


Hence, the amount earned in 7.5 hours is $67.5

Answer:
<u><em>Mmeasure is exactly 180°</em></u>
semi-circle because the measure of a whole circle is 360°.
<u><em> Arc :</em></u>
The arc of a circle consists of two points on the circle and all of the points on the circle that lie between those two points. It's like a segment that was wrapped partway around a circle. An arc is measured not by its length (although it can be, of course) but most often by the measure of the angle whose vertex is the center of the circle and whose rays intercept the endpoints of the arc. Hence an arc can be anywhere from 0 to 360 degrees.
Answer:
C. 3x
Step-by-step explanation:
The first two choices give 1 solution each.
The last choice gives an infinite number of solutions.
Choice C. gives no solution.
3x + 9 = 3x
Subtract 3x from both sides.
9 = 0
Since 9 = 0 is false, equation 3x + 9 = 3x has no solution.
Step-by-step explanation:
To find this percentage, it will make it easier if it is worded differently. Put it "15 is what percent of 50?"
To find the percentage, simply divide 15 by 50 then multiply that quotient by 100.
15 / 50 = 0.3
0.3 x 100 = 30 = 30%
Answer:
The answer is G
Step-by-step explanation:
2 to the power of 3 is 8.
3 to the power of 2 is 9
so we end up with the equation
8x9x7
which equals 504.
