Steels is equal to x and plastic pipes is equal to y
5x + 50y = $1000
6x + 40y = $100
Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).

Answer:
y is NOT a function.
Step-by-step explanation:
The equation given to us is:
x² + 3y² = 3
Rearrange the equation:
3y² = 3 - x²
y² = (3 - x²)/3
y² = 1 - (x²)/3
y = ±√(1 - x²/3)
For any equation to be a function, there should be only one output for one input. Which means that for any value of x, there should be only one value of y. However, in this equation, as the underroot gives two values of any terms under it, it shows that if we put any value of x, we'll get 2 values of y. Therefore, y is not a function.
