Answer:
£518
Step-by-step explanation:
Asking price = original cost × markup%
A = 280(1.85) = 518
2x-2(-2+1)=4
Distribute the -2 to the numbers in parantheses.
2x+4-2=4
Combine all numbers
2x+2=4
Subtract 2 from both sides
2x=2
Then divide by two
x=1
Hey there! Remember that perpendicular lines are the negative reciprocal to the original slope. With that in mind, the best way to find the slope is by using equation m=y2-y1/x2-x1, so then if we plug this in we get:
-4-3/2-(-1)
As -4 is our y2, -3 is our y1, 2 is our x2, and -1 is our y1.
You should get -7/3, that’s the original slope. Since this is a perpendicular line we MUST FLIP it and CHANGE THE SIGN.
So our FINAL answer would be: 3/7
Hope that helps!!!
The answer should be 0.97
