PR = PQ + QR = 40
Substitute PR and QR into the equation above
40 = 5x - 2 + x + 12
Combine like terms
40 = 6x + 10
Subtract 10 from both sides
30 = 6x
Divide both sides by 6
5 = x
PQ = 5x - 2= 5(5) - 2 = 23
Remember, PR = PQ + QR
40 = 23 + QR
Subtract 23 from both sides.
17 = QR
PQ = 23
Answer:
PQ = 23, QR = 17
Step-by-step explanation:
(3x+1)/(x^2-6)
f/g(x)=f(x)/g(x)=(3x+1)/(x^2-6)
y=4
You can ignore the 3 and 6 because this has no y value change(rise over run)
This is a straight horizontal line so the equation is y=4.
Slope=0
10x+12y=300
