If JK is formed by J(-7,-8) and K(1, 4), determine if L(-9,5) lies on the perpendicular bisector. perpendicular Part A What elements do you need to show to confirm that Point L is on the Perpendicular Bisector of JK? Part B Find the elements you described in Part A. Explain your work. Part C Verify if Point L is on the Perpendicular Bisector of JK. Justify your conclusion.

a

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
