The first equation would be, x+y=25. The second equation would be 5x+10y=150. When dealing with money you need to attach the value of the money to the variables
Let's work out the discriminant b^2 - 4ac:-
D = (-5)^2 - 4*1*7 = 25 - 28 = -3
A negative discriminant shows that there are NO real solutions Answer
Well the prim factorization of a number is just all the prime numbers you need to get that number, so to get the prime factorization of -115 you have to start with -1 x 115, and I'll just continue this through sort of a factor pyramid
-1 x 115
-1 x 5 x 23
Those are all the prime numbers you need, really
The value of y from the expression is y = 3/2(j-k)
<h3>Subject of formula</h3>
Given the expression below
2/3y + k = j.
Subtract k from both sides
2/3y = j - k
Divide both sides by 2/3
(2/3y)/2/3 = (j-k)/(2/3)
y = 3/2(j-k)
Hence the value of y from the expression is y = 3/2(j-k)
