y + 4 ≤ |x-2|

please explain how to solve and graph it. Also please show a graph.
| = an absolute value bar, it kinda looks like 1

Answers

Answer:

y ≤ |x - 2| + 4

Step-by-step explanation:

step (1)

move the 4 to the other side, so it would look like:

y≤ |x-2| + 4

step (2)

now we can start graphing it, you would first start on the x axis moving it to the right. so your point on the graph should be (2,0) {don't graph a point there though}

the reason we do this is because the absolute value means the opposite so everytime there is a number in the absolute value being added or subtracted by just x then we move it the opposite side.

then from that (2,0) we go up four which would now make it (2,4). that is our first point and vertex so graph that.

now in y≤ |x-2| +4 you have to note that if there is nothing next to the equality and the absolute value, then it will become a 1. so our equation will now look like y ≤ 1 |x-2| + 4. so with that from our (2,4) point, we go up one and to the right one and to the left one. So there should be two more points at (3, 5) and (1, 5).

we then keep following the pattern of going up one and the right one and to the left one. the graph line should be in a V shape.

step (3)

now there is one last thing you need to do which is shading. what you're going to do first is check the inequality sign. if the inequality sign has a line under it (meaning equal to) then the line will be a solid line. if it doesn't then there should be a dashed line. our inequality sign has a line under it so it is a solid line.

then we need to figure out where to shade, above or below. if the y is greater than the rest of the equation then that means you need to shade above the V shape. however, if it were to be less than the rest of the equation you would shade below the V shape.

in this problem since the y is less than the rest of the equation, shade downwards.

i hope this answered your question and sorry if my explanation was hard to understand, its a pretty lengthy and confusing but it was the only way i knew of how to explain :))

If JM=30 and LM=8, what is KM?

Answers

If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.

How to determine the length of side KM?

In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;

Side JL = [(30 + 8) × x]/2

Side JL = 38x/2

Side JL = 19x.

Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;

19x = √[(30² + x²)(x² + 8²)]/2

38x = √[(30² + x²)(x² + 8²)]

By taking the square of both sides, we have:

38²x² = (900 + x²)(x² + 64)

38²x² = 900x² + 57,600 + x⁴ + 64x²

38²x² = 964x² + 57,600 + x⁴

(x² - 240)² = 0

x² = 240

x = √240

x = 15.49 units.

The correct answer is 336.

How many ways can the psychologist select a person to draw, a person to read, and a person to record time?

By using the arrangement calculation formula:

⇒ [tex]A^{3}[/tex][tex]^{8}[/tex]  

⇒ 8 × 7 × 6

⇒ 336

The correct answer is 336.

How do you calculate an arrangement?

Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=

Answers

Considering the zeros, the graph for the sinusoidal function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.

The sine function is given by:

[tex]F(x) = A\sin{Bx}[/tex]

In which:

The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].

In this problem:

We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:

[tex]\frac{2\pi}{B} = 14[/tex]

[tex]B = \frac{2\pi}{14}[/tex]

[tex]B = \frac{\pi}{7}[/tex]

Thus:

[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]

Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:

[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]

The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

What is the value of (f. f)(6)?
1) 1 2) 2 3) (4) -2

Answers

A composite function combines two or more functions to generate a new function.

The value of [tex]\mathbf{f(f(6))}[/tex] is -2

The require parameter is:

[tex]\mathbf{f(f(6))}[/tex]

First, we calculate f(6)

From the graph (see attachment)

[tex]\mathbf{f(6) = 2}[/tex]

So, the function [tex]\mathbf{f(f(6))}[/tex] becomes:

[tex]\mathbf{f(2)}[/tex]

In other words,

[tex]\mathbf{f(f(6)) = f(2)}[/tex]

Next, we calculate f(2)

From the graph

[tex]\mathbf{f(2) = -2}[/tex]

So:

[tex]\mathbf{f(f(6)) = -2}[/tex]

Hence, the value of [tex]\mathbf{f(f(6))}[/tex] is -2

HELP PLEASE
Lines l and m are parallel lines cut by transversal n. Angle R is measured by (3x +12)° and angle S is measured by (5x +8)°.
What is the measure of angle s?
A-90°
B-108°
C-72°
D-20*

Answers

Answer:

x = 20

Step-by-step explanation:

Lines l and m are parallel so the sum of given angles is = 180

3x + 12 + 5x + 8 = 180 add like terms

8x + 20 = 180 subtract 20 from both sides

8x = 160 divide both sides by 8

x = 20 replace x with 20 in given expression to calculate any measure.

The equation of the line in point slope form is:

Answers

Answer:  (y-9) = -4(x-1)

Step-by-step explanation: The format of a point-slope line is y − y1 = m(x − x1), where x1 and y1 are a known point on a line with slope m.  Given slope of -4 and a point of (1,9):

(y − y1) = m(x − x1)

(y − 9) = -4(x − 1)

I believe HTML & MySQL are the easiest coding languages for beginners. If you are a starter you might prefer to take HTML which is comparatively really easy & understandable as well. HTML allows you to create webpages in no time with simple coding & there's no use of binary digits. Moving onto MySQL..this is also easy but it's advanced when compared to HTML. But, the work is more neat & good if you program it through SQL. After mastering both of them you can go for Python / Java, which are hard but it should be ok if you studied the first 2 languages.
