To determine the equation of the line perpendicular to line GH, we need to know the slope of line GH. We calculate it as follows:
mGH = 3 - 1 / 15 - 7 = 1/4
The slope of the line perpendicular is the negative reciprocal of the original slope. Therefore, the slope would be -4.
The line passes through the midpoint of line GH. The points of the midpoint would be ( 7+15 /2 , 1+3 /2 ) = (11, 2).
y - 2 = -4(x - 11 )
y = -4x + 46
The answer is 11. You multiply 25 and 12.5 first. then once you find out how much money you get each week, you divide the 3437.5 by the number you got, which is 312.5. Divide 3437.5 by 312.5
Answer: -115 should be added to 18 to get a sum of -97.
