Help! please i cant figure it out.
ki77a [65]

let's recall that the graph of a function passes the "vertical line test", however, that's not guarantee that its inverse will also be a function.

A function that has an inverse expression that is also a function, must be a one-to-one function, and thus it must not only pass the vertical line test, but also the horizontal line test.

Check the picture below, the left-side shows the function looping through up and down, it passes the vertical line test, in green, but it doesn't pass the horizontal line test.

now, check the picture on the right-side, if we just restrict its domain to be squeezed to only between [0 , π], it passes the horizontal line test, and thus with that constraint in place, it's a one-to-one function and thus its inverse is also a function, with that constraint in place, or namely with that constraint, cos(x) and cos⁻¹(x) are both functions.

One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,
AlladinOne [14]

Answer:

<h3>             97, 485 and 197</h3>

Step-by-step explanation:

x       - the first number

One number is 5 times a first number:

5x    - "one" number (the second number)

A third number is 100 more than the first number:

x + 100   - the third number

x + 5x + x+100   - the sum of the three numbers

x + 5x + x+100 = 779

            -100         -100    

    7x = 679

   ÷7       ÷7

      x = 97

5x = 5•97 = 485

x+100 = 97 + 100 = 197

Check:

97 + 485 + 197 = 779
