4 seconds, so whatever the letter is for the answer I have provided, select it
-20=-4x-6x
4x+6x=20
10x=20
x=20:10
x=2
proof:
-20=-4×2-6×2
-20=-8-12
(-8)+(-12)=-20
You would pay 80% of the original price because 1/5 is 20% and you would subtract 20 from 100 to get 80 as your answer
Hope this Helps :3
These are vertical angles, meaning they're always the same length.



Answer:
-9-(-3)/0-(-3) = -3/3 = -1
y+9= -1(x-0) <u><em>Point Slope form</em></u>
y+9<u>-9</u>= -1x<u>-9</u>
y= -x-9 <em><u>Slope Intercept form</u></em>
y<u>+x+9</u> = -x-9 <u>+x+9</u>
y+x+9= 0 <u><em>General form</em></u>
