6(x-k)=5x+4

show that x must be an even number.

See Below

Step-by-step explanation:

We will use distributive property [a(b+c) = ab + ac] to simplify the left-hand side of the equation and add like terms and solve for x first. Process shown below:

To show x is ALWAYS AN EVEN number, we can plug in a value for k (even and odd) to show that x becomes always even.

Even Number Case:

k = 2 (2 is an even number, any even would be the same):

x is 16, which is even number

Odd Number Case:

k = 3 (3 is an odd number, any odd would be the same):

x is 22, which is an even number.

Hence, x will always be an even number (shown).

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
