100 dollars should be a one time fee so that has to be added to the equation, and since it is a one time fee it should not have a variable next to it.
It also says that you have to pay 720 dollars per month, so it has to have a variable next to it to show the number of months that she needs to pay that amount of money.
The answer should be D.
y= 720x +100

Answer:
x=2, y=4. (2, 4).
Step-by-step explanation:
x+y=6
3x-2y=-2
---------------
y=6-x
3x-2(6-x)=-2
3x-12+2x=-2
5x-12=-2
5x=-2+12
5x=10
x=10/5
x=2
y=6-(2)=6-2=4
Answers:
x = 51
y = 39
===========================================================
Explanation:
The angles 39 and x form a right angle, aka 90 degree angle. This is shown by the small square angle marker.
One equation to solve is x+39 = 90. Doing so leads to x = 51 after subtracting 39 from both sides.
Similarly, another equation to solve is x+y = 90. Plug in x = 51 and isolate y
x+y = 90
51+y = 90
y = 90-51
y = 39
Generally the value of y would be 34 because same two square roots of n multiplying each others would equal to n by the definition.
Although it is easy to predict the solution of y-value, I will be showing you how to solve the radical equation for y-term which will be useful.
So from the equation, convert √34 × √y to √34y
Then we square both sides to get rid of the square root.
Divide both sides by 34 so we can finally isolate the y-term.
Hence the value of y is 34.
