The figure has 5 lines of symmetry. the answer is C...........
The equation that can be used to determine the tax rate, x is ;44.31 = 42 + (x% of 42) where x = 5.5%
<h3>How to write equation</h3>
- Cost of a shirt = $12.50
- Cost of each shorts = $14.75
- Cost of two shorts = 2 × $14.75
= $29.5
- Total cost = $12.50 + $29.5
= $42
- Total amount paid = $44.31
Total = total cost + x% of total cost
44.31 = 42 + (x% of 42)
44.31 = 42 + 42x/100
44.31 - 42 = 42x/100
2.31 = 42x / 100
x = 2.31 ÷ 42/100
= 2.31 × 100 /42
= 231/42
= 5.5%

Good evening ,
Answer:
{(1,6),(2,2),(4,7),(3,2)}
Step-by-step explanation:
As a function , f has a unique image for each number of the domain.
for instance, the first set can’t represent a function because 1 has more than one image(number).

Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (- 2, - 8 )
d = 
= 
= 
= 
= 
= 4
To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R
7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5
Angle R = 12x + 20
12(5) + 20
60 + 20
80
Option C is your answer.
