Can someone help with this question

  x^2/4 +y^2/9 = 1

Step-by-step explanation:

It is reasonable to start with the form ...

  (x/a)^2 +(y/b)^2 = 1

where "a" is the length of the semi-axis in the x-direction (2), and "b" is the length of the semi-axis in the y-direction (3).

Then you have ...

  (x/2)^2 +(y/3)^2 = 1

The preferred form of this has the denominators multiplied out:

 x^2/4 +y^2/9 = 1

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.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
