Jermaine graphs a point on the y-axis. which of these must be the true about the ordered pair for the point?

a. the x-coordinate is 0.
b. the y-coordinate is 0.
c. the x-coordinate is negative.
d. the y-coordinate is negative.

A. The x coordinate is 0.

Step-by-step explanation:

Since the point is graphed on the y-axis we can assume it has to be some value of y and x = 0 or  (0,y) where no matter what the y is, the x value has to be 0 in order for the point to be on the y-axis.

why B is wrong:

y coordinate that is 0 could still have an x value that is greater than or less than 0 which wouldn't be on the y-axis

why C is wrong:

the x coordinate cannot be negative as any negative x value pulls the point away from the y-axis

why D is wrong:

the y coordinate can be negative but if an x value is selected anywhere else it can pull away the point from the y-axis

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.
