hii please help i’ll give brainliest if you give a correct answer please please hurry it’s timed (this isn’t math but nobody’s answering)

It is math but i think they just dont like people asking their grade level they want 3rd grade level stuff, (i know right? it's weird) so let me answer your question! Here's what we know, Student 1 rides in a moving car traveling east, nothing we can do so far so lets continue, she estimates that the car is going 20 kilometers per hour. Student 2 is standing on the side walk and estimates it going 50 kilometers per hour. The question asks which best explains the difference? your in luck I'm in 7th and we have been learning this in science so let me Answer/explain this to you.

velocity- the rate of displacement of a moving object over time.

acceleration - the rate of velocity change over time.

the correct answer is Acceleration and Velocity have different have different values because they have different motion.

Think of it like your in a car, and it says that the cars going 20 miles per hour ok, I could be on the sidewalk could look and say "oh! it seems like that cars going 50 miles per hour!" The cars motion is Acceleration and me on the sidewalk seeing it is Velocity. Hope this helps! Have a great day! =D

A. All motion is relative to the frame of reference chosen for measurement.

Step-by-step explanation:

Student 1 riding in the car is going at a certain speed. He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.

The difference in estimates is due to their frames of reference.

A. All motion is relative to the frame of reference chosen for measurement.

linear

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
