Answer:
x= -
Step-by-step explanation:
First move the x on the right side the the left side. Now your equation is
2x+
=
Next move 1/2 to the right side. Now your equation is 4x=
. Next divide both sides by 4 to isolate "x." Now your equation is x= -
Hope this helped and have a great day.

Answer:
b. (1, 13).
Step-by-step explanation:
Here's a pic of my work. You can put either equation on the other side of the equal sign, because they both equal Y. therefore, they equal each other.
The first is in the form y=Mx+b where m is the slope and b is the y-intercept. Start at 600 on the y-axis and graph with a slope of six. The second is in the same form but the y-intercept is 0, so start at the origin and graph with a slope of 8. The last is in the form y=b+mx, so start at 1300 and graph with a slope of 3. Remember, slope is rise/run or (change in y)/(change in x). Since the domain and range start at 0 these graphs will only be in the first quadrant with an x limit of 650 and a y limit of 1500.
The variation equation is qr = 25
<h3>How to determine the equation?</h3>
An inverse variation is represented as:
qr = k
Where k is the constant of variation
When q = 10 and r =2.5, we have:
k = 10 * 2.5
Evaluate
k = 25
Substitute k = 25 in qr = k
qr = 25
Hence, the equation is qr = 25
