Answer:
1)Yes
2)No
Step-by-step explanation:
1) 3x^2 = -27
3 (-3)^2 = -27
Once you substitute your value in for x, you can follow the rule PEMDAS to solve the equation.
3 (-9) = -27
-27 =-27
2) 10 - 5x = y
In an ordered pair, the first number is x and the second number is y.
10 - 5 (-4) = 10
10 - 20 = 10
-10 = 10
-10 ≠ 10

Parentheses
Exponents
Multiplication
Division
