Answer:

$268.38

Step-by-step explanation:

First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.

Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38

Okay.
Well, first of all you need to know what an x-intercept is.
It's the point of when the line crosses over the x-axis. For this, situation it crosses twice. An x-intercept written out is normally written out as (#, 0)
Out of that table you have two that apply to (#, 0)
(-6, 0) and (11,0)
the question is asking for a positive x-intercept. I'm guessing you know the difference. between negative and positive. but just in case, I'll use the number 5. As a positive: 5 As a negative: -5
So, you have -6 and 11.
the 6 is negative(-) the 11 is positive(+).
So your answer would be (11,0)

I hope this helped! :)

Answer:

so x=3

Step-by-step explanation:

f(x) = 2

We want to find the x value when y =2

Going across where y = 2

Then go down to find the x value x=3 when y = 2

f(3) =2
