Is y= x2-1 a linear equation

1 answer:

3 0

Answer: With the way you wrote it, I don't know. I'm assuming that it's $y=x^2+1$ . If that's the case, then no it's not linear.

Step-by-step explanation:

It's not a straight line. Graph it.

It's frustrating seeing questions like yours where the person asking literally does not even think through about their question. Next time, at least try the problem on your own instead of just deciding that you can't do it. This is an extremely easy problem, and I'm guessing you're just copying answers on here. The naivety here is palpable.

Can you add and subtract integers and surds together?

Ne4ueva [31]

Answer:

Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.
