Which inequality describes the graph

Which Inequality Describes The Graph

Answers

Answer 1

Answer:

y < 1/2x - 2

Step-by-step explanation:

Find the slope of the graph, we can find the slope of the graph by using the formula y2 - y1/x2 - x1. But in order to do so, we must find two perfect points.

Point 1: (0,-2)

Point 2: (4,0)

Now, we would put these points into the formula.

0 -(-2) = 2

4 - 0 = 4

2/4 = 1/2

Therefore, the slope of this graph is 1/2

Now we must find the y intercept, which can be found based on where the line intersects with a y coordinate (ex: 0,y). Based on that, we can come to the conclusion that -2 is our y-intercept

In order to proceed we must know what a linear equation is. A linear equation contains the following:

y = mx + b

m of mx represents the slope, you would leave x as it is.

b represents the y intercept

We have already found what each is, so we can go ahead and put in our slope and y-intercept into the linear equation.

y = 1/2x + -2

Because, we are dealing with an inequality problem, the equal sign must be replaced with an inequality sign and that is determined based on the area of the graph that is shaded.

Since, the graph is shaded downwards we will be using the "less than sign", in addition if you haven't noticed, the line is dotted so we will NOT be using any "equal to symbols"

So, after applying all of this together, we can conclude that the inequality that describes this graph is y < 1/2x - 2

Step-by-step explanation:

We can solve all of them by writing the equations in a general form

This is a function transformation of

where:

a=Factor of vertical stretch

b=Horizontal shift (- shifts right, + shifts left)

c=Vertical shift (+ shifts right, - shifts left)

The original function has its vertex in [tex](0,0)[/tex] so the horizontal shift will be the new x coordinate in the new vertex and the vertical shift will be the new y in the new vertex like this:

[tex]f(x)=\frac{1}{2}|x+1|-\frac{3}{7}\\b=1=HorizontalShiftof-1\\c=-\frac{3}{7}=VerticalShiftof-\frac{3}{7}\\(-1,-\frac{3}{7})\\f(x)=-\frac{3}{5}|x-5|+\frac{2}{3}\\b=-5=HorizontalShiftof5\\c=\frac{2}{3}=VerticalShiftof\frac{2}{3}\\(5,\frac{2}{3})\\f(x)=\frac{1}{2}|x|-\frac{4}{5}\\b=0=HorizontalShiftof0\\c=-\frac{4}{5}=VerticalShiftof\frac{4}{5}\\(0,-\frac{4}{5})\\f(x)=-\frac{3}{2}|x-\frac{2}{5}|+\frac{5}{3}\\b=-\frac{2}{5}=HorizontalShiftof\frac{2}{5}\\c=\frac{5}{3}=VerticalShiftof\frac{5}{3}\\(\frac{2}{5},\frac{5}{3})[/tex]

Suppose f(x)=x^2.What is the graph of g(x)=f(5x)?

Answers

Answer:

D

Step-by-step explanation:

g(x)=f(5x)

this means plugging in 5x for x in f(x):

g(x)=f(5x)=(5x)^2

which can be further simplified:

5^2x^2=25x^2

Since the coefficient of x being larger means a vertical stretch, the answer is D

example:

g(2)=f(5*2)=f(10)=f(10^2)=100

so for g(x), it has the coordinates (2,100), which is most definitely not C

Final answer:

The graph of g(x) = f(5x) is a parabola that is narrower than the graph of f(x) by a factor of 1/5, with the vertex remaining the same.

Explanation:

The graph of g(x) = f(5x) can be obtained by substituting 5x for x in the function f(x) = x^2. So, g(x) = f(5x) = (5x)^2 = 25x^2. This means that the graph of g(x) is a parabola that is narrower than the graph of f(x) by a factor of 1/5. The vertex of the parabola remains the same, but the x-values and the y-values are scaled.

Is the graph of the equation continuous or discrete

Answers

Answer:

Total length of the x inches long pieces = 4x inches

She has to cut another piece = 7.75 inches

Total length = 4x + 7.75

This is what y represent, so

y = 4x + 7.75

The graph of the equation is continuous

Answer:

The required equation is [tex]y=4x+7.75[/tex] and the graph of the equation is continuous.

Step-by-step explanation:

Consider the provided information.

Julie needs to cut 4 pieces of yarn,

Let x  represent the length of each yarn.

Then the length of 4 pieces will be: 4x

y represents the total length of all of the yarn that Julie decides to cut

Therefore the required equation that can be used to determine the total length of all of the yarn is:

[tex]y=4x+7.75[/tex]

Here, the graph is continuous, because the length of yarn can be any number.

Which statement could describe the dog’s movement 5 seconds after the command was given?

Answers

Final answer:

The dog’s movement 5 seconds after the command, considering different frames of reference for speed, can be described by the distance it would have traveled: either 25 meters on the sidewalk (at 5 m/s) or 10 meters from the student's perspective (at 2 m/s).

Explanation:

The student's question pertains to describing the dog’s movement 5 seconds after the command was given, considering the dog's speed. Since we have learned that the dog has different speeds in different frames of reference—5 m/s on the sidewalk and 2 m/s in the student’s frame—we can describe the dog’s movement based on these speeds. If the dog started moving at the moment the command was given and continued to move for 5 seconds, we can calculate the distance it would have covered in that time.

For the sidewalk's frame, where the dog's speed is 5 m/s, the dog would have covered a distance of:

Distance = Speed × Time

Distance = 5 m/s × 5 s = 25 meters

In the student’s frame, where the dog's speed is 2 m/s, it would have moved:

Distance = 2 m/s × 5 s = 10 meters

The statement that could describe the dog’s movement 5 seconds after the command was given is that the dog could have traveled either 25 meters from its starting point on the sidewalk or 10 meters from the student's perspective, depending on the frame of reference being considered.

The temperature in Fargo North Dakota was 6°F at noon. By 4 PM the temperature dropped to -10°F. What integer represents the change in temperature?

Answers

The change expressed as an integer is -16.

The integer that represents the change in temperature is -16°F.

How to solve for the change in temperature

To find the change in temperature, we need to calculate the difference between the final temperature and the initial temperature.

The initial temperature was 6°F, and the final temperature was -10°F. To calculate the change, we subtract the initial temperature from the final temperature:

Change in temperature

= Final temperature - Initial temperature

                             = (-10°F) - (6°F)

                             = -10°F - 6°F

                             = -16°F

Therefore, the integer that represents the change in temperature is -16°F.

What is the first step needed to solve 2/5x-6=-16?

Answers

Answer:

Add 6 to both sides.

Step-by-step explanation:

You are trying to solve for x in this type of question. In this case, note that there is a equal sign, and that what you do to one side you do to the other. Also note that to isolate the x (your goal), you must do the opposite of PEMDAS. (Note that PEMDAS = Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction).

So your first step is to add 6 to both sides.

2/5x - 6 (+6) = -16 (+6)

Simplify. Solve:

2/5x + (-6 + 6) = -16 + 6

2/5x = -10

_________________________________________________________

Finish finding for x.

Multiply the recipricol of the fraction to both sides to isolate the x. Multiply 5/2 to both sides:

(5/2)(2/5)x = (-10)(5/2)

x = (-10)(5/2)

x = (-50)/2

x = -25

x = -25 is your answer.

The total cost for 9 bracelets, including shipping was $72. The shipping charge was $9. Define your variable and write an equation that models the cost of each bracelet.
4. Use the equation you have written above determine the cost for each bracelet. Show the algebraic steps that it takes to find the answer. Provide your conclusion.

Answers

Answer:

a) Equation: 9x+9 = 72

b) x =7

Step-by-step explanation:

The total cost of 9 bracelets = $72

Shipping charge = $9

a) Define your variable and write an equation that models the cost of each bracelet.

Let x be the cost of one bracelet, the equation will be

9x + 9 = 72

As 9 bracelets were there and the shipping cost was 9 and total cost was 72.

b) Use the equation you have written above determine the cost for each bracelet. Show the algebraic steps that it takes to find the answer.

Now solving the equation to find the value of x that represent cost of each bracelet

9x + 9 = 72

Adding -9 on both sides

9x +9 -9 = 72 -9

9x = 63

Dividing both sides by 9

9x/9 = 63/9

x = 7

The value of x=7 so, the cost of each bracelet is $7

c) Provide your conclusion.

So, each bracelet was of cost $7 and $9 was the shipping charge. so, the total cost is $72.

We would check whether our equation is satisfied.

9x+ 9 = 72

9(7) + 9 = 72

63 + 9 = 72

72 = 72

The equation is satisfied.

Answer:

The cost of each bracelet is: $7

Step-by-step explanation:

Let's call x the cost of each bracelet.

Then the cost of the 9 bracelets is:

9x

If we know that the cost of the bracelets plus the shipping was $ 72 and the cost of shipping is $ 9.

So

The total cost was:

[tex]9x + 9 = 72[/tex]

Now we solve the equation for the variable x.

[tex]9x + 9 = 72[/tex]

Subtract 9 on both sides of equality

[tex]9x + 9-9 = 72-9[/tex]

[tex]9x = 72-9[/tex]

[tex]9x = 63[/tex]

Divide by 9 on both sides of equality

[tex]\frac{9}{9}x = \frac{63}{9}[/tex]

[tex]x = \frac{63}{9}[/tex]

Final answer:

Without additional information, we cannot determine the exact percentage of students age 15 and above who travel to school by bus.

Explanation:

To find the percentage of students age 15 and above who travel to school by bus, we need to compare the number of students who travel by bus to the total number of students in that age group. However, we don't have that information in the given question.

We need more data to calculate the percentage. Without additional information, we cannot determine the exact percentage of students age 15 and above who travel to school by bus.

As the number of pages in a photo book increases, the price of the book also increases. There is an additional shipping charge of 15%. The price of a book can be modeled by the equation below, where P = the price of the book, 20 is the printing charge, 0.5 is the charge per page, and x = the number of pages: (2 points)

P = (20 + 0.5x) + 0.15(20 + 0.5x)

Jennifer wants to purchase a book but only has $62.10 to spend. What is the maximum number of pages she can have in her book?

Answers

Answer:

22

Step-by-step explanation:

Solve the inequality  (20 + 0.5x) + 0.15(20 + 0.5x)   ≤ $62.10 for x:

20 + .5x + 3 + 0.75x ≤ 62.10

Combining the x terms, we get:

20 + 3 + 1.25x ≤ 62.10.

Combining the constants on the left:

23 + 1.75x ≤ 62.10

Combining the constants:

1.75x = 39.10

Solving for x:  39.10/1.75 = 22.34

Thus, the max number of whole pages she can have in her book is 22.

A local public library decides to track the number of hours that a certain computer is being used. The table represents the number of hours, y, which is dependent on the number of days, x.

What is the linear equation that represents this situation?

Answers

Answer:

Second option: y = 8x-3

Step-by-step explanation:

The equation tha satisfies the given values will be the required linear equation

So,

y = 8x + 45

For x=3 and y=21

21 = 8(3) +45

21 = 24+45

21≠69

As this equation is not satisfied by the values, it is not the correct option..

For y = 8x-3

x=3,y=21

21 = 8(3)-3

21 = 24-3

21=21

x=5, y=37

37 = 8(5)-3

37=40-3

37=37

x=7, y=53

53 = 8(7)-3

53 = 56-3

53 = 53

As the equation is true for all values of x and y. This is this correct option..

Answer:

Choice B

Step-by-step explanation:

Formula for slope:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]y_2 = 1\\y_1 = -10\frac{2}{3} \\\\x_2 = -3\\x_1 = 4[/tex]

[tex]1 - (-10\frac{2}{3}) = 11\frac{2}{3} \\-3 - 4 = -7[/tex]

[tex]\frac{-11\frac{2}{3} }{-7} = \frac{5}{3} = 1\frac{2}{3}[/tex]

What is y-5=3(x+1) in slope intercept form

Answers

Answer:

y=3x+8, :m=3, b=8

Hope this helps!

The line y - 5 = 3(x + 1) in the form of slope intercept is y = 3x + 8 and slope of the line is 3, y-intercept is 8.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a line:

y - 5 = 3(x + 1)

In slope intercept form:

y = 3x + 3 + 5

y = 3x + 8

Thus, the line y - 5 = 3(x + 1) in the form of slope intercept is y = 3x + 8 and slope of the line is 3, y-intercept is 8.

Answer:

D. 9/4 ÷ 3/4

Step-by-step explanation:

In the question, the number line represents 9/4 divided into 3 equal units.

The size of each unit is 3/4 as shown.

Showing that 3/4 divides 9/4 into 3 divisions:

9/4 ÷ 3/4

= 9/4 x 4/3

= 9/3 x 4/4

= 9/3 x 1

= 3 x 1

= 3

Hence, the number line represents three divisions given by 9/4 ÷ 3/4.

The Dust Bowl During the 1930s, extreme drought and high winds made life incredibly difficult in the Great Plains region of the United States. In many areas, rainfall was forty percent less than normal. The soil became extremely dry, and when strong winds blew, they created tremendous dust storms. These so-called black blizzards were so thick that they made daylight seem like dusk. During this terrible period, the Great Plains region of the United States was named the Dust Bowl. Over the next few years, the drought continued, and the winds created more dust storms. In some places, the drought and high winds lasted for eight years.
