Answer: f-1(y) = (y-3)/2
Step-by-step explanation:
f(x) = 2x+3, written as a flow diagram:
2x+3
The Inverse Function goes the other way:
Inverse
So the inverse of: 2x+3 is: (y-3)/2
The inverse is usually shown by putting a little "-1" after the function name, like this:
f-1(y)
We say "f inverse of y"
So, the inverse of f(x) = 2x+3 is written:
f-1(y) = (y-3)/2
Yes, it does.
Ex:
2 + 3 = 3 +2 => 5 = 5
For negative integers:
(-2) + (-3) = (-3) + (-2) => -5 = -5
Step-by-step explanation:
If James wants to cover both of his children at his current salary until they both can support themselves on their own, he would need a 10-year term policy (if the youngest moves out when he/she is 21) with a face value of $500,000 (current salary-$50,000*10 years).
33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
Note:
<span>a(b) = ab = a x b = a times b</span>
let's recall that a square has four equal sides, so if one side is x + 4½ long, then all four are x + 4½ long, and the perimeter is simply the sum of all four.
let's first off, convert the mixed fraction to improper fraction.
