Answer:
A) JK and LM will be parallel to each other.
Step-by-step explanation:
On reflection on 
line the x co-ordinate changes with y co-ordinate and y co-ordinate changes with x co-ordinate
Points on line EF
On reflection of this line on the new points we get for line JK are
Points on line GH
On reflection on y=x line the new points we get for line LM are
Slope of line JK
Slope of line LM
For two line to be parallel, their slopes will be same.
Since slopes of lines JK and LM are same therefore we can say that these are parallel to each other.
Answer:
2 outfits
Step-by-step explanation:
first you have the total amount of money he has.
next subtract the amount of money he spends on the new bicycle
500-273.98=226.02
next find the total cost of the 3 bicycle reflectors
7.23 times 3 = 21.69
Subtract that total from the remaining amount of money left
226.02 - 21.69 = 204.33
Then subtract the helmet from the remaining money
204.33 - 42.36 = 161.97
now divide the remaining money by 78.12 to find out how many outfits he can buy
161.97 / 78.12 = around 2.07
So the answer is he can only buy 2 outfits with the remaining money
(you can not buy 2.07 outfits)

Answer:
12^4 or 20736
Step by Step Instructions:
really all you have to do is subtract the exponents. 12^7-12^3=12^4, if you want to expand the numbers you can do it that way too. 12^7=35831808, 12^3=1728, 35831808/1728=20736 (which is the same as 12^4)
Answer:
nonagon - 9
Step-by-step explanation:
- pentagon - 5
- nonagon - 9
- hexagon - 6
- octagon - 8
We have that
<span>4x -2y =22------> clear variable y
2y=4x-22--------> y=4x/2-22/2---------> y=2x-11-----> equation 1
2x + 4y = 6------> equation 2
substitute equation 1 in equation 2
2x+4*[2x-11]=6-----> 2x+8x-44=6----> 10x=50------> x=5
then
y=2x-11----> y=2*5-11----> y=-1
