Answer:

  • Abel is 7 and Asare is 17 years old

Step-by-step explanation:

Let the age of Abel is x and age of Asare is y.

Three times the age of Abel is four more than the age of Asare:

  • 3x = y + 4

And

In three years, the sum of their ages will be 30 years:

  • x + 3 + y + 3 = 30

We got two equations.

Simplify and solve by substitution:

  • y = 3x - 4
  • x + y = 24

  • 3x - 4 + x = 24    Substitute y
  • 4x - 4 = 24
  • 4x = 28
  • x = 7

Find y:

  • 17 + y = 24
  • y = 7

For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at x = 5. What is definitely true about x = 5? Both f(x)
kati45 [8]

Answer: 'Both f(x) and g(x) have the same output value at x = 5' is true statement.

Step-by-step explanation:

Since, for a function f(x), x is the input value and f(x) is the output value,

Here, f(x) and g(x) are two functions,

Such that f(x) = g(x) at x = 5,

⇒ The output value of both function is equal for the input value of x.

⇒ Fourth option is the true statement.

Note : For other options, the adequate information is not given.

That's why we can not say them true.
