The sum of two numbers that differ by 3 is x, what is the value of the greater of the two numbers?
jolli1 [7]

Answer:


Step-by-step explanation:

You really don't have enough information to solve this with one answer. You want a value for y and there is no what to limit it to just 1 set of values. For example if x = 23 then

x = y + y - 3

x = 2y - 3

23 = 2y - 3           Add three to both sides

23+3 =  2y           Combine

26 = 2y                Divide by 2

26/2 = 2y/2          Do the division

13 = y

The smaller number is 13 - 3 = 10

Their sum is 13 + 10=23           But that answer is not unique.

====================

Suppose x = 13

13 = 2y - 3              Add 3

13 + 3 = 2y

16 = 2y

y =8

The larger number = 8

The smaller number = 5

=======================

The best I can do is give you the equation which is

x = 2y - 3

If f(x)=2x+3÷2,find f-1(x).​
BartSMP [9]

The required inverse function  f^{-1}(x) = (2x - 3 ) / 4.

Given that,
f(x) = (2x+3) / 2

To find  f^{-1}(x)

<h3>What are functions?</h3>

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x = f^{-1}(x)
 f^{-1}(x) = (2x - 3 ) / 4


Thus,  the required inverse function  f^{-1}(x) = (2x - 3 ) / 4.

What is the surface area of the cube?
lorasvet [3.4K]
A cube has 6 sides, and each side has the area of 16 (since 4 times 4 is 16) so if you multiply 16 and 6 you get 96 mm2 as the surface area.
