Solve –|2x+3|=1 for x it might have more than one answer

1 answer:

3 0

There is no answer.

Logically speaking, absolute value returns an output that is zero or positive.

Rearranging the equation gives:
|2x + 3| = -1

No matter what we substitute, we cannot get a negative number after applying the absolute value.

Therefore, the expression is undefined.

Use the points (0, 4) and (-2, 3) to find the slope of the line and give the equation of this line.

Sauron [17]

Answer:

Choice C: $m=\frac{1}{2}; y=\frac{1}{2} x+4$

Step-by-step explanation:

To find your slope do:

$\frac{y^2-y^1}{x^2-x^1}$

$\frac{3-4}{-2-0}=\frac{-1}{-2} =\frac{1}{2}$

that's how you get 1/2

4 is just the y-int.

For which values of x is the function

max2010maxim [7]

Answer:

x = - 5, x = - 11

Step-by-step explanation:

Given

y = $\frac{x+4}{(x+5)(x+11)}$

The denominator cannot be zero as this would make y undefined.

Equating the denominator to zero and solving gives the values that x cannot be, that is

(x + 5)(x + 11) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x + 11 = 0 ⇒ x = - 11

Thus

x = - 11 and x = - 5 are excluded values.
