Please help! (: I know the middle one is 3
Olenka [21]

<u><em>When x = -2</em></u>, f(x) = -7(-2) + 3 = 14 + 3

<u><em>x = 17</em></u>

<u><em>When x = 5</em></u>, f(x) = -7(5) + 3 = -35 + 3

<u><em>x = -32</em></u>

All you have to do to solve the function is substitute the value of x into the equation.

Use expressions for odd integers to confirm the conjecture that the product for two odd integers is an odd integer.
Mandarinka [93]

k, n - integers  

2k+1  - an odd integer

2n+1  - another odd integer

The product of them:

  (2k + 1)(2n + 1) =

= 4kn + 2k + 2n + 1 =

= 2(2kn + k + n) + 1

The product of integers (2kn) is integer

and the sum of them (2kn+k+n) also is integer

So  (2k + 1)(2n + 1)  = 2(2kn + k + n) + 1  is an odd integer
