The answer is (2,5).

Check:

2y=3x+4

2(5)=3(2)+4

10=6+4

10=10 Good

The answer is (2,5)

<h3><u>Question</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. If the sum of the digits of the original number is 13, then find the number. </u>

<h3><u>Statement</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. </u><u>T</u><u>he sum of the digits of the original number is 13</u><u>.</u>

<h3><u>Solution:</u></h3>

Let one of the digit of the original number be x.
So, the other digit = (13-x)
Therefore, the two digit number = 10(13-x) + x = 130-10x+x = 130-9x
The number obtained after interchanging the digits is 10x+(13-x) =9x+13
Therefore, by the problem

130-9x-(9x+13) = 45

or, 130-9x- 9x-13 = 45

or, -18x = 45-130+13

or, -18x= -72

or, x = 72/18 = 4

or, x = 4

So, the original number = 130-9x = 130 -9(4) = 130 - 36 = 94

<h3>Answer:</h3>

The number is 94.

I think the answer you have given isn't right. The answer should be 94.

Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)

$f(x)=3x- \frac{1}{2}$
there are no restrictions
all real numbers can be used
all real numbers can result

so the answer is domain and range for both is all real numbers
