Answer:
One number is 561
The other number is 23.6854
Step-by-step explanation:
x = y^2 One number = the square of another
x + y^2 = 1122 The sum of the two numbers is 1122
Substitute y^2 in for x on the second equation.
y^2 + y^2 = 1122 Combine like terms on the left
2y^2 = 1122 Divide by 2
y^2 = 1122/2
y^2 = 561 Take the square root of both sides.
y = 23.6854
x = y^2
x = 561
y^2 = 561
1. Y=4
2. Y=2
3. Y=X
4. Y=2
(X,Y)
i hope this helps
Step-by-step explanation:
A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.
B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.
how many months for the cost to be the same?
![\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4](https://tex.z-dn.net/?f=%5Cstackrel%7BA%7D%7B12%2B28m%7D%3D%5Cstackrel%7BB%7D%7B20%2B26m%7D%5Cimplies%2012%2B2m%3D20%5Cimplies%202m%3D8%5Cimplies%20m%3D%5Ccfrac%7B8%7D%7B2%7D%5Cimplies%20m%3D4)
well, since the cost for both is the same, we can just get A's, knowing that B is the same
![12+28(4)\implies 12+112\implies 124](https://tex.z-dn.net/?f=12%2B28%284%29%5Cimplies%2012%2B112%5Cimplies%20124)
The answer is -4
because when you minus 11 and 20 that will get you -9 and then you add 5 that get you the answer
