You would foil (x+1)(x+11)
x^2 + 12x + 11
2x2^2=8+3=11
11 is your answer I believe.
First you want to work the discount for the TV.
$187.13*0.75=$140.3475 (this will get you the price of the TV after the discount.)
Now round the answer $140.3475 to the nearest hundredth. The new answer is $140.35. So the price of the TV after the discount is $140.35. Next use this equation to solve for the tax that would be added to the price of the discounted TV:
(t*d)+d=p
In that equation t=taxes, d=discounted TV price, and p=price total. Now input the values you know.
(0.09*140.35)+140.35=p
Multiply what is in the parentheses first.
12.6315+140.35=p
Add the two numbers together.
152.9815=p
Round the end amount to the nearest hundredth.
152.98=p
So now you know that the total price of the discounted TV after tax is added is $152.98. I hope you could understand this and it helps! :D
Answer:
only the v-shaped graph is a function
Step-by-step explanation:
the circle, the vertical line, and the sideways parabola would not pass the 'vertical line test' which is where, if a vertical line is drawn through the graph then the line would not intersect the graph in more than one point
