When x-y=3 work out the value of y-x

The value of y-x is (-3)

Solution:

Given: The value of x-y=3

To find: The value of y-x

Let's multiply the equation (1) by (- 1) on both sides,

On multiplying the sign,

The above equation can also be written as,

Multiplication of signs:

In simpler terms, when we multiply two integers with the same signs, the result is always positive and when we multiply two integers with different signs, the result is always negative.

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.
