CLAIM:
Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.
In the before image, a car is moving along a track at a constant speed towards a motionless wheel.
In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.
THE QUESTION:
Which Claim below best explains what causes the wheel to spin after contact with the car?
1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.
2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.
3 - The wheel pushes the car, causing it to go faster
4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.
Answer:
The wheel moved because of the car.

What equation represents the proportional relationship displayed in the table?
x 2 4 6 8
y 10 20 30 40
Enter your answer by filling in the box to complete the equation.
Answer:
Y=5x
Step-by-step explanation:
Every number in the y placement is the product of something times 5. Example :
2 * ___ = 10?
All you need to do is divide the product by the first number.
Answer:
its 5
Step-by-step explanation:
2x5=10 4x5=20 6x5=30 8x5=40
notice that all are multiplied by 5 this means they are proportional.
to find the answer enter in the box the number that every x value is being multiplied by

m > 0, what is the value of m?
(PLEASE HELP ME!!!! THIS IS TIMED SO PLEASE HELP!!! I WILL MARK YOU BRAINIEST IF YOUR ANSWER IS CORRECT!!!!!)
Answer:
y=-4/5x+2
Step-by-step explanation:
SORRY FOR THE LATE RESPONSE
slope-intercept form is y=mx+b
b is the y-intercept -> 2
m is the slope, which would be the rise/run -> -4/5
to identify the slope all you need to do is pick two points on the line, and find the direction of the line from left to right. rise/run basically means you find the distance going up and down first, and then the distance from left to right next.
now just put the equation together-> y=-4/5x+b
let me know if this helped, or was even right lol

0.2 ( 10 - 5c ) = 5c - 16
Answer: c = 3
Step-by-step explanation: Distribute 0.2 to (10-5c)
2-1c=5c-16
Then subtract 2 on both sides and subtract the 5c.
-1c=5c-18
-6c=-18
Then divide -6 to -18
-18/-6 = 3
Jack's tent is shaped like an isosceles triangle. The height of the tent measures 7 feet and the diagonal side measures 9 feet. Find the length of the tent's base. Please explain how you got the answer, thank you! Need help asap. (Triangle photo in image)

its 7ft
Step-by-step explanation:
A rhombus has sides 10 cm long and an angle of 60°. Find the diagonals of the rhombus.
Since all the sides are equal, the altitude is
10 sin60° = 5√3
To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°
The distance from Jamestown to Kenneville is 180 miles, the distance from Kenneville to Elizabeth City is 300 miles, and the distance from Elizabeth City to Jamestown is 240 miles. Which of the following equations could NOT be used to determine if the lines connecting the towns form a right triangle?
A.180 squared plus 300 squared equals 240 squared,
B.300 squared minus 240 squared equals 180 squared,
C.80 squared plus 240 squared equals 300 squared,
D.300 squared minus 180 squared equals 240 squared

2z+3=9
Answer:
Z=3
Step-by-step explanation:
As long as ur happy thats all that matters
Answer:
z=3
Step-by-step explanation:
Let's solve your equation step-by-step.
2z+3=9
Step 1: Subtract 3 from both sides.
2z+3−3=9−3
2z=6
Step 2: Divide both sides by 2.
2z/ 2 = 6/ 2
z=3

Answer:
11 and 23
Step-by-step explanation:
So, what is scaling?
Scaling is basically when a shape is inlarged or shruken by a specific amount on all sides.
In this case, one of the shapes side's is 10.
Now, they say that the scale value is more than 1. What does this mean?
It means that the new, scaled number is going to be at least as big as 10.
We dont have to worry about finding a exact number, since they do not give us any information to scale with.
So, all we have to do is look at the graph, and see what numbers are larger than 10.
Is 2 units larger than 10? No, thats only about 1/5 the orginal size, not larger than 1.
Is 5 units larger than 10? No, thats only abouit 1/2 the orginal size, not larger than 1.
How about 11? Is it larger than 10? Yes, its about 11/10 the orginal size, which is bigger than 1.
Finally we have 23? Is it larger than 10? Yes, its a little over 2 times bigger than the orginal size.
So your two answers are:
11 and 23
Hope this helps! :)
