The sum of three numbers is 79 . the third number is 2 times the second. the first number is 5 less than the second. what are the numbers?

first = 21 - 5 = 16

second  = 21

Third = 21*2 = 42

Step-by-step explanation:

first + second + third = 79

Let the second number = x

third = 2*x

first = x - 5

So we get

x - 5 + x + 2x = 79

4x - 5 = 79                  Add 5

4x - 5 + 5 = 79 + 5     Combine

4x= 84                         Divide by 4

4x/4 = 84/4

x = 21

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
