Answer:
y= -1/4x + 14
Step-by-step explanation:
- the slope of a perpendicular line is the negative reciprocal of the original line, so the slope of the new line is -1/4
- now, y= -1/4 x + c, to find c we substitute the values of x and y from the given point [ (8,12) ]
- (12) = -1/4*(8) + c, after you rearrange you get c = 14
- place the value of c to get y= -1/4x + 14
Original figure = 24
Output figure = 18
(24 - 18)/24 = 6/24 = 1/4 This is the loss.
18/24 = 3/4 is the scale factor. Choice D.
Yes, 104.12 is greater than 104.02.
Remember.
positive number x positive number = positive number
positive number x negative number = negative number
negative number x positive number = negative number
negative number x negative number = positive number
So if both numbers have the same sign, either both positive or both negative, then the product will be positive.
