Consider the end behavior of the function g(x)=-1/3|x|+9 and complete the statements.
As x approaches negative infinity, g(x) approaches [ Negative, Positive ] infinity.
As x approaches positive infinity, g(x) approaches [ Negative, Positive ] infinity.
Answer: thanks for this answer, I was working on this problem.
As x approaches negative infinity, g(x) approaches [ Negative] infinity.
As x approaches positive infinity, g(x) approaches [ Negative] infinity.

Which statements about the graphs of y = 1/2sin x and y = 1/2sin(x - π /2) are true?
Select all that apply.
A) The graph of y = sin(x - π/2) is shifted units π /2 units left from the graph of y=1/2sin x.
B) The graph of y = 1/2sin(x - π/2) is shifted units π /2 right from the graph of
y = 1/2 sin x.
C)The period of y=1/2sin(x - π/2) is π/2, and the period of y = 1/2sin x is 2 π.
D)The amplitude of y = 1/2sin(x - π/2) is half the amplitude of y = 1/2 sin x.
E)The amplitude of y=1/2 sin(x - π/2) is the same as the amplitude of y = 1/2 sin x.
The correct answer is option B) The graph of y = 1/2sin(x - π/2) is shifted units π /2 right from the graph of y = 1/2 sin x.
How do you describe a graph?
For most graphs, give a brief description including the title and axis labels, and mention trends not already described in the text. For simple charts, state the actual data points. For more complex charts, an ideal description would include the data in a table or list.

If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your answer should be written as a decimal rounded to the nearest tenth if necessary.
The number of pages the student can read in a minute is an illustration of rates.
The time left to complete the whole book is 90 minutes
From the complete question, the student's rate is:
[tex]\mathbf{Rate = 50\ pages/hr}[/tex]
The number of pages is:
[tex]\mathbf{Total = 100\ pages}[/tex]
First, we calculate the time to read the whole book
[tex]\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}[/tex]
[tex]\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}[/tex]
[tex]\mathbf{Total\ Time = 2\ hours}[/tex]
The number of the student has read is:
[tex]\mathbf{Pages = 25}[/tex]
Next, we calculate the time spent on the 25 pages
[tex]\mathbf{Time\ Spent = \frac{Pages}{Rate}}[/tex]
[tex]\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}[/tex]
[tex]\mathbf{Time\ Spent = 0.5\ hr}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Spent = 30\ minutes}[/tex]
So, the time left is:
[tex]\mathbf{Time\ Left = Total\ Time - Time\ Spent}[/tex]
This gives
[tex]\mathbf{Time\ Left = 2\ hours- 30\ minutes}[/tex]
[tex]\mathbf{Time\ Left = 1\ hour, 30\ minutes}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Left = 90\ minutes}[/tex]
Hence, the time left is 90 minutes

the width of a rectangle is 3 inches less than its length the perimeter of the rectangle is 26 inches what is the width of the rectangle
Answer:
5
Step-by-step explanation:
W = x
L = x + 3
P = 2W + 2L
26 = 2(x) + 2(x + 3)
26 = 2x + 2x + 6
26 = 4x + 6
26 - 6 = 4x

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.
How fast did Car A travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Enter your answer in the box.
Answer:
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Step-by-step explanation:
Answer:
Step-by-step explanation:
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
x= 132 meters traveled by both cars

(5, -3) move it seven units to the left amd one unit up. Please help-
Answer:
That would be -2, -2
Step-by-step explanation:
This is because if you go left or right it changes the x in (x,y). And when you move up or down it changes the y. So 5 seven units to the left is like 5 - 7 which is -2. And one unit up from -3 is -3 + 1 which is -2. Then you get your answer which is (-2,-2)
Find two consecutive even integers such that 4 times the smaller integer is 44 less than 7 times the larger integer
Answer:
let x be the smaller number.
let x + 2 be the larger number.
4 times the smaller number is 2 more than 3 times the larger number.
in equation form, this becomes:
4x = 3 * (x+2) + 2
simplify this to get:
4x = 3x + 6 + 2 which becomes:
4x = 3x + 8
subtract 3x from both sides of this equation to get:
x = 8
this means that x+2 = 10
the smaller number is 8 and the larger number is 10.
4 times the smaller number is equal to 32.
3 times the larger number + 2 is equal to 32.
requirements of the problem check out ok, so the solution is good.
the smaller number is 8.
the larger number is 10.

Graph the line that passes through the points (-5, 3) and (−1,−1) and determine the equation of the line.
A line can be drawn by joining the plot of the two given points
Please find attached the graph of the line created with MS ExcelThe equation of the line is y = -x - 2Reason:
Given points on the line are (-5, 3) and (-1, -1)
From the given points, the graph of the line can be plotted with MS ExcelThe slope, m, of the line is given as follows
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we have;
[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]
The equation of the line in point and slope form is therefore;
y - 3 = -1·(x - (-5) = -x - 5
In slope and intercept form, we have;
y = -x - 5 + 3 = -x - 2
