Is -2 a solution to 4x^(3)-x^(2)+16x-4

Mathematics
1 answer:
sergiy2304 [10]3 years ago
3 0

Answer:

Not a solution

Step-by-step explanation:

In order for x=-2 to be a solution, the result after substituting must be 0:

4(-2)^3-(-2)^2+16(-2)-4\stackrel{?}{=}0

4(-8)-4-32-4\stackrel{?}{=}0

-32-40\stackrel{?}{=}0

-72\neq0

Therefore, x=-2 is not a solution to 4x^3-x^2+16x-4

Which fraction below represents a terminating decimal?
9966 [12]
<h3>Answer: C.  3/10</h3>

A terminating decimal only happens when the fraction has a denominator with factors of 2 and/or 5. No other factors are allowed (other than 1).

Something like 1/12 has the denominator 12 with factors 2*2*3. That '3' means we won't have a terminating decimal. Similarly, the fractions 2/9 and 2/3 won't convert to a terminating decimal either.

3/10 on the other hand does convert to a terminating decimal and 3/10 = 0.3

Rewrite the absolute value function y=|x|, as two linear functions, one that has the domain x&lt;0, and one that has the domain
bekas [8.4K]

Answer:

y = x for x ≥ 0 and y = - x for x < 0

Step-by-step explanation:

The absolute value function is written as y = |x| and it is defined as following

|x| = x when, x ≥ 0 and |x| = - x when, x < 0.

Therefore, the equations for the domain of x ≥ 0 is y = x

and the equation for the domain of x < 0 is  y = - x (Answer)
