Inverse Functions. An inverse function goes the other way! Let us start with an example: Here we have the function f(x) = 2x+3, written as a flow diagram: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2 .
Answer:
Step-by-step explanation:
Integers with a product of 567 are ...
567 = 1·567 = 3·189 = 7·81 = 9·63 = 21·27
The last of these pairs of factors have a difference of 6, so they are the answers.
Jackie's number is 27; Adrian's number is 21.
_____
You could let "a" represent Adrian's number and write the equation ...
a(a +6) = 567
a^2 +6a +9 = 576 . . . . . complete the square
(a +3)^2 = 24^2 . . . . . . . write as squares
a = -3 +24 = 21 . . . . . . . . take the positive square root; subtract 3
Adrian's number is 21; Jackie's number is 27.
Yes the treasury can determine whether the gold bar is
really weighing 500 ounces.
We can use the equation:
7 x + 11 y = 500
where x is the amount of the 7 ounce weights while y is
the amount of 11 ounce weights.
We know that x and y should be whole numbers therefore
this is solved through trial and error.
By trial and error I got:
x = 7 and y = 41
<span>
So that;</span>
7 * 7 + 11 * 41 = 500
49 + 451 = 500
500 = 500
<span>Hence they can use 41 11-ounce weights and 7 7-ounce
weights to test</span>
