Find f(-2) if f(x) = x + x + 7. f(-2) =
viktelen [127]

Answer:

f(-2) = 3

Step-by-step explanation:

Given that,

f(x) = x + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2) + (-2) + 7

= -2-2+7

= -4+7

= 3

Hence, the value of f(-2) is equal to 3.

the sum of two numbers is 105 if the larger number is 13 more than the smaller number find both sumbers
irga5000 [103]

Answer:

46 and 59

Step-by-step explanation:

let the smaller number be n then the larger number is n + 13 and summing them gives the equation

n + n + 13 = 105

2n + 13 = 105 ( subtract 13 from both sides of the equation )

2n = 92 ( divide both sides by 2 )

n = 46

the 2 numbers are n = 46 and n + 13 = 46 + 13 = 59
