Answer:
<em>The total price David paid for the computer is $933.12</em>
<em />
Step-by-step explanation:
The cost of the computer will be $1,080 with 20% off and 8% sales tax.
20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864
Now we have to find 8% of 864.
864(0.08)=$69.12
So the total price will be 864+69.12= $933.12
Answer:
20
Step-by-step explanation:
100 + 60 = 160
There are 180 degrees in a triangle so we do 180-160 = 20
Use the general definition:
|x - a| ≤ k => - k ≤ x - a ≤ k
So, |a - 9| ≤ 4 => - 4 ≤ a - 9 ≤ 4
Which is a - 9 ≥ - 4 and a - 9 ≤ 4.
That is the second option.
Answer: a - 9 ≤ 4 and a - 9 ≥ - 4
Perpendicular would have a slope of 1/8 and a line paralell to y=-8 would be y=-8+5 because they have the same slope but different y-intercepts.
