Sam will be = 15 - 3 = 12 years.
If you can use a calculator, enter (4/1/4)/(4/1/2) and you will get 1/2
2x - 17?
= -17 +2x (using commutative property of addition, changing order and sum remains the same)
answer is A) -17 + 2x
If the 2 is an exponent, it should be marked as such.
“3x2” means 3x⋅2
“3x^2” means 3x²
3x²+8x = 0
Discriminant = 8²-4(3)(0) = 64
Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
I hope it's helpful!
