Step-by-step explanation:
The bike cost $199 to get $199 you do a number line then label 520 then at the end label 321 so then you do -20 then -100 then -50 then -20 then -9. so now you add them up 20+100+50+20+9 which equals =199
so bike cost $199
then 520%×199= 1034.8
or 520%×321=1669.2
so the percentage is 1669.2 or 1034.8 probably 1669.2 but they bot count.
The reflection across the x-axis only change the signal of the y coordinate. Hence, the new point is

.
First, you should solve both equations for the same variable. Since the first one is already solved for y, solve the second equation for y as well.
6y = 2x + 6 Divide both sides by 6
y =

x + 1
You can see that both lines have a slope of

.
Lines that have the same slope are
parallel lines.
Hey there! :D
Use the distributive property.
a(b+c)= ab+ac
6(9x+2)+2x
54x+12+2x
56x+ 12 <== equivalent expression
I hope this helps!
