Each of these statements are part of True/False game. Which statement is correct?
sergey [27]

Answer:

E. (The function is exponetial)

Step-by-step explanation:

We look at the output values and subtract them from their previous value to see it's slope.

6-2 = 4

12-6 = 6

4 ≠ 6, meaning that the slope is not constant.

4 < 6, meaning that the slope is increasing, meaning the function is exponential.

The sum of 2 numbers is 50. The sum of 1/4 of the first number and 2/3 of the second number is 25.What are the numbers?
tino4ka555 [31]

Answer:

First number: 20

Second number: 30

Step-by-step explanation:

First#:   x

Second#:   y

Constraints:

   x + y = 50      

   1/4x + 2/3y = 25

Isolate variable y:

   x + y = 50    

  -1/4 (x + y = 50 )

 -1/4x - 1/4y = -12.5

  Add equations the two equations to eliminate x:

    -1/4x - 1/4y = -12.5

     1/4x + 2/3y = 25

  _________________

       5/12y = 12.5

           5y = 150

              y = 30

Substitution to find x:

       x + y = 50  

       x + 30 = 50

              x = 20
