2x-6=0
2x-6+6=0+6
2x=6
2x/2=6/2
x = 3
Answer:
B - closing costs are increased
Step-by-step explanation:
All of the other options are advantages to purchasing points. You want lower monthly payments (a), a tax break (c), and lower interest rate (d)
First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2
y=mx+b, where m is the slope and b is the y-intercept
y=x/2+b, using any point we can solve for b, I'll use (20, 10)
10=20/2+b
10=10+b
0=b, so the cost function is:
C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)
(x - 5)² = 0 ⇔ x - 5 = 0 because only 0² = 0.
The answer to this questing is 100, because (23 x 2) + (18 x 3) = 100
