Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
Answer:
Step-by-step explanation:
Round to 2 inches
A = π(2²) = 4π = 4(3.14) = 12.56 in²
A = π(2.43²) = 18.541386 ≈ 18.54 in²
Here is the equation:
You have to use PEMDAS
Since multiplication is before addition, first multiply. You need to multiply 4 by 3.
Here is your new equation:
All you need to do is add the two numbers. Add:
That means your answer is 30
