Answer: The graph is attached. Please note that the logarithm function is defined for non-negative Reals only. Therefore the log(-x) only exists in the negative interval (-inf,0). Please let me know if you have any questions.

Which of the following points is a solution of y > |x| + 5?

Morgarella [4.7K]

You can do this one simply just by plugging in the values of x and y for each answer.
Note: (0,5) is just a way to right x=0 and y=5

Try answer A (0,5)
$y\ \textgreater \ |x|+5$
$5\ \textgreater \ |0|+5$
$5\ \textgreater \ 0+5$
$5\ \textgreater \ 5$
This is not true. 5 is not bigger than 5 so A is not the answer

Try answer B (1,7)
$y\ \textgreater \ |x|+5$
$7\ \textgreater \ |1|+5$
$7\ \textgreater \ 1+5$
$7\ \textgreater \ 6$
This is true so answer B works!

Might as well try answer C (7,1)
$y\ \textgreater \ |x|+5$
$1\ \textgreater \ |7|+5$
$1\ \textgreater \ 7+5$
$1\ \textgreater \ 12$
1 is obviously not greater than 12 so C does not work

The answer is B (1,7)

16 - 3x = 4 + x <br> solve please

likoan [24]

Answer:

x = 3

Step-by-step explanation:

Solution for 16-3x=4+x equation:

Simplifying

16 + -3x = 4 + x

Solving

16 + -3x = 4 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

16 + -3x + -1x = 4 + x + -1x

Combine like terms: -3x + -1x = -4x

16 + -4x = 4 + x + -1x

Combine like terms: x + -1x = 0

16 + -4x = 4 + 0

16 + -4x = 4

Add '-16' to each side of the equation.

16 + -16 + -4x = 4 + -16

Combine like terms: 16 + -16 = 0

0 + -4x = 4 + -16

-4x = 4 + -16

Combine like terms: 4 + -16 = -12

-4x = -12

Divide each side by '-4'.

x = 3

How do you find the complex and real roots for x^4-3x^2+2=0

pogonyaev

X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0

so either x^2 - 2 = 0 or x^2 - 1 = 0

so x^2 = 2 or x^2 = 1

so x = sqrt 2 , - sqrt2, 1 , -1 Answer

all the roots are real

One card from a deck of cards Is selected, it's is replaced, and another card is chosen. What is the probability that the first

Elis [28]

Answer:

1/ 8

Step-by-step explanation:

Given that:

Number of red cards in deck = 26

Number of diamonds in deck = 13

Number of cards in deck = 52

Recall :

Probability = required outcome / Total possible outcomes

Probability of choosing a red :

P(red) = 26 / 52 = 1/2

With replacement :

Probability of diamond :

P(diamond) = 13 / 52 = 1/4

Hence,

Probability of first card red, then second card diamond equals

P(red) * P(diamond)

1/2 * 1/4

= 1/8
