Answer:
number 24 = 73
Step-by-step explanation:
133-50 = 73
number 25 = 180
160+ 20= 180
Answer:
A)
Step-by-step explanation:
4x = 4 times a number. You are subtracting two from 4x. 12 is the outcome.

Answer: 6</h3>
===================================================
Explanation:
Each point listed is of the form (x,y)
The input x is fed into the f(x) function to get a y = f(x) output.
Recall that the inverse function undoes everything the original function does.
This means that when we determine the inverse function for a list of points like this, we just swap each x and y.
So if
then,
Again all I've done is swap each x and y value.
From here, we look through the inverse function set and look for the point when x = 1. We see the point (1,6) is in the set.
Therefore,
step-by-step explanation:
since it tells you the equation 'y = 20x' and y is the number of gallons where as x is minutes
the independent variable = number of gallons
the dependent variable = minutes
and the number(s) to fill in the table
x , y
( 0, 0 )
( 1, 20 )
( 2, 40 )
( 3, 60 )
( 4, 80 )
and the relationship between x and y is linear because you can clearly see the graph having especially a straight line that is not interfering with itself
hope this helps you! :)
Answer:
2700 years
Step-by-step explanation:
The exponential function for the fraction remaining is ...
r(t) = (1/2)^(t/5730)
where r is the remaining fraction and t is the time in years. We can solve for t to get ...
log(r) = (t/5730)log(1/2)
t = 5730·log(r)/log(1/2)
For the given r=0.72, the age of the artifact is estimated to be ...
t = 5730·log(0.72)/log(0.5) ≈ 2700 . . . years
