The average cost in 1990 is <span>$12,841.</span>
Answer:
m GHI = 82°
Step-by-step explanation:
59+39=98
180-98=82 <==== answer
180 is the total amount of degree
A, x-intercept is when y=0, so in this case when y=0, the equation becomes 5x=0. Therefore, x must equal 0 for 5x=0. so y=0 and x=0 so the answer it (0,0), which is A.
Answer:
neither
Step-by-step explanation:
The second and 3rd one can be modeled by by y = 100/x but the first one and the fourth one do not follow that, so the answer is neither. The first and fourth are y = 80/x
Put the values in and you will see the equations for yourself.
One
y = 80/2
y = 40
The 80 came from looking at this as an indirect variation. y = k/x
y = 40
x = 2
y = k/x
40 = k/2 Multiply both sides by 2
40 * 2 = k
k = 80
Two
y = k/x
20 = k/5
k = 20 * 5
k = 100
Answer:
Step-by-step explanation:
For this case we must determine the inverse of the following function:
Step 1:
We would write
or 
Step 2:
We clear x:
Step 3:
"x" and "y" are exchanged:
The inverse is:
