What is the linear equation that represents this situation?
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..

Which statement could describe the dog’s movement 5 seconds after the command was given?
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.
Julie needs to cut 4 pieces of yarn, each with the same length and a piece of yarn 7.75 inches long. Let x represent the length of each of the equal pieces of yarn that Julie decides to cut what is the equation that can be used to determine the total length of all of the yarn that she ends up, cutting,y? Is the graph of the equation continuous or discrete
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.

Write the point slope form of the equation of the line passing through the points (-5, 6) and (0.1).
For this case we have by definition, that the equation of a line in the point-slope form is given by:
[tex](y-y_ {0}) = m (x-x_ {0})[/tex]
Where:
m: It's the slope
[tex](x_ {0}, y_ {0}):[/tex] It is a point through which the line passes.
[tex]m = \frac {y2-y1} {x2-x1}[/tex]
We have as data two points, replacing:
[tex]m = \frac {1-6} {0 - (- 5)}\\m = \frac {1-6} {0 + 5}\\m = \frac {-5} {5}\\m = -1[/tex]
We substitute a point, then the equation is:
[tex](y-1) = - 1 (x-0)\\(y-1) = - x[/tex]
Answer:
[tex](y-1) = - x[/tex]
Answer: [tex]y-6=-(x+5)[/tex]
Step-by-step explanation:
The Point-slope form of the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where "m" is the slope of the line and [tex](x_1,y_1)[/tex] is a point on the line.
We know that this line passing through the points (-5,6) and (0,1), then we can find the slope with this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substituting, we get:
[tex]m=\frac{1-6}{0-(-5)}=-1[/tex]
Finally, we can substitute the point (-5,6) and the slope into [tex]y-y_1=m(x-x_1)[/tex], then:
[tex]y-6=-(x-(-5))[/tex]
[tex]y-6=-(x+5)[/tex]

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.

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?
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.

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)
Answer:
Point-slope equations:
y - 5 = 4/3 (x - 6)
or
y - 1 = 4/3 (x - 3)
Step-by-step explanation:
Given two coordinate points (6, 5) and (3, 1)
Slope = (5 - 1)/(6 - 3) = 4/3
Point-slope equations:
y - 5 = 4/3 (x - 6)

It underlines the slope of the line and a point on the line (that exists not the y-intercept).The slope formula exists utilized to calculate the inclination or steepness of a line. It discovers application in choosing the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis. The slope of a line exists defined as the change in the "y" coordinate concerning the change in the "x" coordinate of that line.Here, the line passes through the points (6,5) and (3,1).
Let,
[tex]$$(6,5)=\left(x_{1}, y_{1}\right)$$[/tex]
[tex]$(3,1)=\left(x_{2}, y_{2}\right)$[/tex]

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?
The integer that represents the change in temperature is -16°F.
How to solve for the change in temperatureTo 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.

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

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

Which statement accurately explains whether a reflection over the Y axis and a 270° counterclockwise rotation would map figure ACB onto itself?
Neither the reflection over the y-axis nor the 270° counterclockwise rotation would map figure ACB onto itself.
Explanation:To determine whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure ACB onto itself, we need to analyze the effects of these transformations.
A reflection over the y-axis would change the x-coordinates of the points, but not the y-coordinates. So, figure ACB would not be mapped onto itself after a reflection over the y-axis.A 270° counterclockwise rotation would change the position of the points by rotating them around the origin. After a 270° counterclockwise rotation, figure ACB would not be mapped onto itself as the shape and position of the points would change.Therefore, neither the reflection over the y-axis nor the 270° counterclockwise rotation would map figure ACB onto itself.

This results means that there are no solutions in the system, because the statment 0 = -12 is false, also lines are parallels, that's the real reason why there's no solution.
Remember that parallel lines won't intercept, and a solution of a linear system means that those lines intercept. So, if they don't, then, there's no solution.
Therefore, the right answer is the first choice.
Need help finding the length of Ac
Answer:
We need to know angle C which is (180 -123 -34) = 23°
We'll use the Law of Sines
Sine (A) / side a = Sine (B) / side b
Sine (34) / 10 = Sine (123) / side b
0.55919 / 10 = 0.83867 / side b
10 * .83867 / .55919 = side b
side b (or line AC) = 14.998
Step-by-step explanation:
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.
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]
[tex]x = \$7[/tex]
