Just times 12 x 7 that should give you the answer
The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.
For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.
-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.
Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.
Answer:
24
Step-by-step explanation:
percent of 280 is 67.2
280×y/100=67.2
280y/100=67.2
2.8y=67.2
divide by 2.8
y=24
verify
280×24/100=67.2
6720/100=67.2
67.2=67.2
