Answer:
$16.40 per CD before tax
Step-by-step explanation:
4 CDs cost $70.40
70.40 / 4 = 17.60 (this includes the tax)
Remove the tax
17.60 - 1.20 = $16.40 per CD before tax
X = 2
Using the trapezoid mid segment theorem, knowing that the mid segment is parallel to the bases and half as long as the sum of the lengths of the bases, we add the lengths of the two bases and set it equal to two times the length of the mid segment.
7x+3+ 15= 16(2)
7x+18= 32
Subtract 18 from both sides.
7x = 14
Divide both sides by 7.
X = 2.
You can check your work by solving for the length of the base 7x + 3.
7(2)+3 =17
Then, add the length of the two bases together.
15 + 17 = 32. Half of 32 equals sixteen, which is your mid segment.
(correct me if i’m wrong, i got the theorem off of the internet and did the rest of the work myself.)
Answer:
If two people have answered, you chose the one you want to give brainliest, and give them a crown on their answer.
Step-by-step explanation:
Answer:
y = -4x + 1
Step-by-step explanation:
The line passes through points (-5,21) and (-4,15)
Slope(m) = change in y ÷ change in x
m = 
m = 
= -36/9 = -4
Taking another point (x,y) on the line and comparing it with point (4,-15):
-4 = 
Cross multiplying gives:
y + 15 = -4x + 16
y = -4x + 1
H= -8. H-2h= 9-1; -h=8; h= -8
