Answer:

a) (-2, 2), (-1, -1), (1, -1), (3, 7)

b) x = 1.4

Step-by-step explanation:

a) Plug in your x & solve for y.

$y = (-2)^2 - 2\\y = 2\\y = (-1)^2 - 2\\y = -1\\y = (1)^2 - 2\\y = -1\\y = (3)^2 -2\\y = 7$

b) Same thing as a, but just plug in 0 for y & solve for x

$0 = x^2 -2\\2 = x^2\\\sqrt(2) = x\\1.4 = x$

If a bored game was originally $25 and it is on sale for $18 , what is the percent discount?

Blizzard [7]

Hi there!

To find the percent discount, we need to divide the new price by the original price without the discount:

18 / 25 = 0.72

Now, we convert this into a percentage, so we can find the <em>percent </em>discount:

0.72 = 72%

Now, we subtract from 100%:

100% - 72% = 28%

So, the answer is 28%.

Hope this helps!
