Well if 1/16 costs $2 then you do 16*2 to find the cost of 16/16 aka 1 pound. 16*2=32 so the answer is x = 32.
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)
Answer:

Answer:
w = 5
Step-by-step explanation:
In the given right triangle, by trigonometric ratio, we have:

Answer:
21 = 21
Step-by-step explanation:
5x + 1 = 21
-1 -1
5x = 20
__ __
5 5
x = 4
5x + 1 = 21 First substitute x for 4
5(4) + 1 = 21 Then continue to solve the problem to get the proof
20 + 1 = 21
21 = 21
