I showed my work and answer in this picture. When simplifying square roots you can split them into a perfect squares root time the remainders
To solve a system of equations by graphing, you must first graph both equations. The solution is the point of intersection of the lines.
To plot these two equations, do this.
First equation.
y = 3x + 1
y = mx + b
b = 1, so plot point (0, 1), the y-intercept.
Now starting at point (0, 1), use the slope, m = 3 = 3/1, to go up 3 units and 1 unit to the right. Plot that point which is (1, 4). Now connect points (0, 1) and (1, 4) with a straight line and extend the line in both directions. That is how you graph the first equation.
Second equation.
Solve it for y.
x - 2y = 8
-2y = -x + 8
y = (1/2)x - 4
y = mx + b
b = -4. Plot point (0, -4) which is the y-intercept. Now from that point, go up 1 unit and right 2 units to point (2, -3), and plot that point. Connect the two points with a straight line and extend it in both directions. That is how you plot the second equation.
The point of intersection of both lines is the solution of the system of equations. Read that point.
Answer:
colby
hourly rate =$8.90
overtime rate = time and a half = 1.5
the hourly overtime rate is the product of the overtime rate and the hourly rate.
hourly overtime rate= overtime rate × hourly rate
= 1.5 × $8.90
= $13.35
Cheryl
hourly rate = $7.10
overtime rate = double time = 2
the hourly overtime rate is the product of overtime rate and the hourly rate.
hourly overtime rate = overtime rate × hourly rate
= 2 × $7.10
= $14.20
<h3>Comparison</h3>
we note that the hourly overtime rate of cheryl is higher than the hourly overtime rate of colby, which implies that cheryl earns more for one hour of overtime.
we are also interested in the difference of the hourly overtime rate:
hourly overtime rate colby — hourly overtime rate cheryl
= $14.20 – $13.35
= $0.85
thus cheryl earns $0.85 more for one hour of overtime than colby .
<h3>result</h3>
<h2>cheryl,$0.85</h2>
