Answer:
im guessing it is 6
Step-by-step explanation:
ok ok hi hi
X, x+2, and x+4 are the numbers where x=odd integer
x+(x+2)+(x+4)=51
3x+6=51
3x=51-6
3x=45
x=45/3
x=15, x+2=17, x+4=19
also you can do the following...
51/3=17
17-2=15
and 17+2=19
Finding the inverse function of 
, it is best described by graph B.
<h3>How to find the inverse of a function?</h3>
Supposing we have a function y = f(x), to find the inverse, we exchange x and y, and isolate y.
In this problem, the function is:
Exchanging x and y:
Working through the function to isolate y:
Which is best represented by graph B.

#SPJ1
The number is composed by two digits, let them be ab, so we have:
a + b = 11
this is a pseudo-equation, we are not multiplying ab or ba, is just the digits order.
ba = ab + 9
The pairs of numbers that could comply with the first equation are:
(2,9)
<span>(3,8)
</span><span>(4,7)
</span><span>(5,6)
</span>But only the last couple <span>(5,6) comply as well with the second condition. Because 65 = 56 + 9
Therefore the unknown number is 56</span>
