A function assigns the values. The inverse of the function is y = (x+5)/2.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
To find the inverse of the function, the function is needed to be solved for x, and then replace x with y and vice versa. Therefore, the inverse of the function will be,
f(x) = y = 2x - 5
y = 2x - 5
y + 5 = 2x
x = (y+5)/2
y = (x+5)/2
Hence, the inverse of the function is y = (x+5)/2.

Answer:
x+(x+30)=72
Step-by-step explanation:
if x is the smaller number and y is the bigger number, then according to the condition (one number is 30 more than the other) y=x+30.
It the sum of the two numbers is 72, then x+y=72.
After substitution y=x+30:
x+(x+30)=72; - the required equation.
⇔ 2x=42; ⇒ x=21 (it is the smaller number)
y=51 (it is the bigger number).
I pretty sure that the answer is 1.
There are 2 basic trangles used in SAT,
45-45-90
30-60-90
if you look in the attachment you will know the relationship between each so
with a 30-60-90 triangle which you have
hypotonuse=2x
hypotonuse=12
2x=12
divide by 2
x=6
I'm not sure about the length, but I'm assuming you mean the longer side
the measure of each leg is 6 and 6 times√3
the lonnger one is 6√3
the answer is 6√3 meters
