5 0

Answer:

x < - 17 or x > 7

Step-by-step explanation:

Inequalities of the form | x | > a always have solutions of the form

x < - a or x > a

For | x + 5 | > 12, then

x + 5 < - 12 or x + 5 > 12 ( subtract 5 from both sides of the inequalities )

x < - 17 or x > 7

The cost of a customer's smartphone bill can be modeled by

Sergio039 [100]

Answer:

C = (g + 5)

Step-by-step explanation:

Given the cost of a customers smartphone bill,

C=10g+50

We are required to factor the polynomial.

First, determine the G.C.D of both terms

The GCD of 10g and 50 is 10

Next, we divide each of the term by 10 and balance it by multiplying the expression by 10.

C = 10g + 50

= 10 (10g / 10 + 50/10)

The cost polynomial factored is C=10(g+5).

Evaluate. 3/4 minus 3/8 Divided by 2/3

user100 [1]

Answer:

3/16 or 0.1875

Step-by-step explanation:

3/4 - ((3/8)/2/3))

= 3/4 - 3/8 * 3/2

= 3/4 - 9/16

= 12/16 - 9/16

= 3/16 or 0.1875

Hope this help you :3

Someone please tell me how to work out this type of problem i completely forgot

fenix001 [56]

Answer:

Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.

Step-by-step explanation:

For x = -5: y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)

For x = -2: y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)

(Etc.)

Then, plot these coordinates and draw a line through them to complete the graph.

Part 3 - Discussion/Explanation Question

SpyIntel [72]

Step-by-step explanation:

Vertical asymptote can be Identites if there is a factor only in the denominator. This means that the function will be infinitely discounted at that point.

For example,

$\frac{1}{x - 5}$

Set the expression in the denominator equal to 0, because you can't divide by 0.

$x - 5 = 0$

$x = 5$

So the vertical asymptote is x=5.

Disclaimer if you see something like this

$\frac{(x - 5)(x + 3)}{(x - 5)}$

x=5 won't be a vertical asymptote, it will be a hole because it in the numerator and denominator.

Horizontal:

If we have a function like this

$\frac{1}{x}$

We can determine what happens to the y values as x gets bigger, as x gets bigger, we will get smaller answers for y values. The y values will get closer to 0 but never reach it.

Remember a constant can be represent by

$a \times {x}^{0}$

For example,

$1 = 1 \times {x}^{0}$

$2 = 2 \times {x}^{0}$

And so on,

and

$x = {x}^{1}$

So our equation is basically

$\frac{1 \times {x}^{0} }{ {x}^{1} }$

Look at the degrees, since the numerator has a smaller degree than the denominator, the denominator will grow larger than the numerator as x gets larger, so since the larger number is the denominator, our y values will approach 0.

So anytime, the degree of the numerator < denominator, the horizontal asymptote is x=0.

Consider the function

$\frac{3 {x}^{2} }{ {x}^{2} + 1}$

As x get larger, the only thing that will matter will be the leading coefficient of the leading degree term. So as x approach infinity and negative infinity, the horizontal asymptote will the numerator of the leading coefficient/ the leading coefficient of the denominator

So in this case,

$x = \frac{3}{1}$

Finally, if the numerator has a greater degree than denominator, the value of horizontal asymptote will be larger and larger such there would be no horizontal asymptote instead of a oblique asymptote.
