Answer:
The X is equal to 1.75
Step-by-step explanation:
3.5X2.25=7.875
14/7.875=1.75
perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10
I believe the original price of the television was 580.56 because 492*18%=88.56 so 492+88.56=580.56 hope this helps
