Answer:

2k

Step-by-step explanation:

3k and -k are both like terms, so you can combine them. Adding opposite signs works in the same way as subtraction, so you can rewrite the expression as 3k-k, which is 2k.

What is the answer to this question?<br> Y=x^2-1 with the input as 5
mixas84 [53]

We can see that, when the input is 5, the output is 24.

<h3>How to evaluate an equation?</h3>

Here we have the equation:

y = x^2 - 1

Where y is the output and x is the input.

We want to evaluate it with the input as 5, so we need to replace the variable x by the number 5, we will get:

y = 5^2 - 1 = 24

Then we can see that, when the input is 5, the output is 24.
