Students are learning a new dance. The students move forward 2.0 meters and tap their feet. Then they move backward 1.0 meter and clap their hands. Finally, they move 0.5 meter forward and stop. What is the displacement of the dancers from their starting part
Answer:
1.5 meters
Step-by-step explanation:
they first move forward 2 meters and then move backwards 1 meter (1 meter from their starting point, and then they move forward 0.5 meters. So the displacement of the dancers from their starting point is 1.5 meters.
0 + 2 = 2
2 - 1 = 1
1 + 0.5 = 1.5

The equation of a line is given by:
y = mx + c
Where m is the slope.
Slope = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
The slope of the linear function is 3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example: y = -3x - 4
Slope = -3 and y-intercept is -4.
We have,
A table that represents a linear function.

We can have points such as:
(x, y) = (2, 7), (5, 16), (7, 22), and (9, 28)
We can select any two points and find the slope.
(2, 7) = (a, b)
(5, 16) = (c, d)
Slope:
= (d - b) / (c - a)
= 16 - 7 / 5 - 2
= 9 / 3
= 3
Slope = 3
Thus,
The slope of the linear function is 3.

Ann took a taxi home from the airport. The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10.
Write an equation to determine the distance in miles (x) between the airport and Ann's home
Find the distance between the airport and Ann's home.
Answer:
$2.10x + 5= $49.10
x=21
Step-by-step explanation:
the x is used for a variable that changes and in this case the mph changes which lead x being the amount of miles that they had drove which at the end ends up multi. with the $2.10 . as for the 5 it was an initial as in it doesn't change.
for the second part
you subtract 5 from each side so you have the total of 2.10x= 44.10 then u divide 2.10 from each side and that will give you x = 21
A tire shop promotes its business using a large model of a tire on its roof. The
model tire uses a scale in which 2 feet represents 3 inches. The actual tire used
to create the model tire has a diameter of 33 inches.
What is the diameter of the model tire on the shop's roof
Help plz!!! I need the work shown
Answer:
Ok, so this tire is 2 feet which is represented by 3 inches.
So, since the tire has a diameter of 33 inches, we multiply 33 by 3
33 times 3 is 99.
The diameter of the motel tire on the shop's roof is 99 inches.

A recipe requires 7/8 stick of butter for each 1 1/4 cups of flour. Find the unit rate of sticks of butter to cups of flour.
Answer:
Let R = unit rate
R = (7/8) ÷ 1_1/4
R = (7/8) ÷ (5/4)
R = (7/8) • (4/5)
R = (7/2) • (1/5)
R = 7/10

If solving a system of linear equations by elimination or substitution I get that 0=0, as final or intermediate step depending on the system, it means (check all that apply)
I have definitely made a mistake and need to review the result

of solution
If the system of equations is 3 linear equations in 3 variables, there might be infinite
number of solutions
If the system of equations is n linear equations in n variables, there is one unique solution
Answer:
If I get 0=0 then it means:
If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutionsIf the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutionsStep-by-step explanation:
Linear equation systems can consist of two or three equations with two or three unknowns respectively.
A system of linear equations in two variables has infinite solutions when the lines made by them overlap each other and similarly a system with three variables has infinite solutions when two lines overlap each other and third plane is parallel to them
Hence,
If I get 0=0 then it means:

Write multiplication expression to represent the change in temperature after the plane ascends 10,000 feet .... Above it says there is a 1.3°F drop in temperature for every thousand feet that an airplane climbs into the sky the temperature on the ground is -2.8°F... part b says what will the temperature b when the plane reach's an altitude of 10,000 feet
Answer:
1.3°F * 10 = 13°F
10.2°F
Step-by-step explanation:
Given that:
Temperature on the ground = - 2.8°F
Change in temperature per 1000 ft rise = 1.3°F
Change in temperature after the plane ascends 10000 ft
Change in temperature per 1000ft rise * (10000/1000)
1.3°F * 10 = 13°F
B.) Temperature at 10,000 feets
Temperature on ground + change in temperature at 10,000ft
-2.8°F + 13°F
= 10.2°F

Find the distance between (-6,8) and (10,-4)
Answer:
use the distance formula you can find it on the net
The distance between (-6,8) and (10,-4) is 20 units.
What is the distance between two points ( p,q) and (x,y)?
The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
We are given that;
The points (-6,8) and (10,-4)
Now,
To use the formula, you need to plug in the values of x1, y1, x2 and y2 into the formula and simplify. For example, to find the distance between (-6,8) and (10,-4), you can do:
d = (10 - (-6))^2 + (-4 - 8)^2
d = (16)^2 + (-12)^2
d = 256 + 144
d = 400
d = sqrt(400)
d = 20
Therefore, the distance formula the answer will be 20 units.

To find the equation of the parabola, first let's write the parent function,
y = a(x-h)^2+k. Ok, now we need to find the vertex and plug it in. Remember, (h,k). When we look at the problem the vertex is (0,4). Therefore we write it as y = a(x-0)^2 +4 or y = ax^2 + 4. Now we need to look to see if it was stretched or compressed. Keep in mind that on a normal parabola, if you move over 1 you go up one. If you move over 2 you go up four. If you move over 3, you go up 9. In this problem, you move over 1, you go up 1. If you move over 2, you go up 4. If you move over 3, you go up 9. From this information, we see that there is no stretch or compression. Therefore the equation of the graph shown is:
y= x^2 +4
