The equation Ax+By=0 goes through the coordinates (-7,-4) and (14,2) What is the value of A?

A = 0

Step-by-step explanation:

System of equations

We have a general equation

Ax + By = 0

We are required to find the value of A, knowing that the ordered pairs (x,y)=(-7,-4) and (14,2) meet the condition.

Use (-7,-4):

A(-7)+B(-4)=0

Or, equivalently:

-7A-4B=0

Use (14,2):

A(14)+B(2)=0

Dividing by 2:

7A+B=0

Adding both equations:

-7A - 4B + 7A + B =0

Simplifying:

-3B = 0

B = 0

If follows that, also

A = 0

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.
