Solve the problem using a system of equations: The difference of the squares of two numbers is 15. The difference of twice the square of the first number and the square of the second number is 30. Find the numbers. (__,__),(__,__)

(3.873, 0) (-3.873,0)

Step-by-step explanation:

let the two numbers be x & y

-=15 ---1

2-=30 --- 2

substract the equation

=15

x=+3.87 or -3.87

and y = 0 when you substitute x^{2} back to the first equation

15-y^2=15

Y^2=0

y=0

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
