If m is the midpoint of xy, find the coordinates of y if x(-1,-3) and m(0.5,-1.6)

The coordinates of Y are (2,-0.2)

Step-by-step explanation:

Let the coordinates of Y be (x,y)

Since M is the midpoint of XY, so

Multiply both sides by 2

Cancel out the 2's from the top and bottom on the right side

Add 1 to both sides

Cancel out -1 and +1 on the right side

Flip the sides

Similarly,

Multiply both sides by 2

Cancel out the 2's on the top and bottom of the right side

Add 3 to both sides

Cancel out -3 and +3 on the right side

Flip the sides

So, the coordinates of Y are (2,-0.2)

answer is c

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
