Find all real solutions:<br> x² - x - 12 = 0
Andrej [43]
Factor the equation. Remember the value should add to the b value and multiply to the c value.

x^2-x-12= 0
(x-4)(x+3)=0

Use the zero product property to find roots
x-4=0
x=4

x+3=0
x=-3

Find the domain of the following piecewise function.
il63 [147K]

Answer:

(2,8]

Step-by-step explanation:

Given

The attached piece wise function

Required

The domain

To do this, we simply consider the inequalities that bound the values of x.

The inequalities are:

2 < x < 4     4 < x < 8   and   x \ge 8

Combine the first two inequalities:

2 < x < 8    and   x \ge 8

For the inequality to be true, we must have:

2 < x \le 8

In interval notation, the inequality is:

How many solutions does the system below have?<br> y=1/2x+1<br> 2y - x = 2
kvasek [131]

Answer:

infinitely many

Step-by-step explanation:

Rewrite these equations as

y = (1/2)x + 1

2y = x + 2

and then solve the second for y:  y = (1/2)x + 1.  Note that these end results are identical.  The two lines coincide; that is, one lies right on top of the other.  Thus, there  are infinitely many solutions.

Which value is in the solution set of |x|+9=-2
Eduardwww [97]

Answer:

The equation has no solutions

Step-by-step explanation:

If we re arrange the equation a little more we will obtain the following

|x|=-11

Which is a contradiction since, the  |x| is always a positive number

Attached is the representation of this function y= |x|

It means, that it doesnt matter what value 'x' has, the answer is the same number but, positive
