Answer:
x ≠ 4 or -2
Step-by-step explanation:
the denominator cannot be zero, so factor the bottom equation to get the zeros and those are the domain restrictions.
3x^2 - 6x - 24 ≠ 0
3(x^2 - 2x - 8) ≠ 0 (factor out a 3)
3(x - 4)(x + 2) ≠ 0 (factor equation)
x ≠ 4, x ≠ -2 (use zero product property to find zeros)
Answer:
A
Step-by-step explanation:
f(x) = 2x^2 – 3x + 1 is a function (its graph is a parabola that opens up), and it is one-to-one (Answer A). For each input, x, this function will return one output.
Answer:
v = 9
Step-by-step explanation:
50 = 6v - 4
50 + 4 = 6v
54 = 6v
6v/6 = 54/6
v = 9
Given:
5 pounds = 2.268 kilograms
To find:
The number of kilograms in 2 pounds.
Solution:
We have,
5 pounds = 2.268 kilograms
Divide both sides by 5.
1 pounds =
kilograms
1 pounds = 0.4536 kilograms
Multiply both sides by 2.
2 pounds = 2×0.4536 kilograms
2 pounds = 0.9072 kilograms
Therefore, the correct option is B.
