Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m.

d = 108m

Mark has created a table to record the number of minutes it took him to walk different distances in meters.

Time
(minutes)
Distance
(meters)
10
1,100
20
2,200
40
4,400
Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony is
meters per minute and the unit rate for Mark is
meters per minute.

On a graph, the line representing Tony’s distance covered with respect to time would be
Mark’s line. So, Tony’s walking speed is
Mark’s.

Answers

Answer:

Tony: d = 108m

Tony walks 108 meters per minute

Mark:

(10,1100),(20,2200)

m = (2200 - 1100) / (20 - 10) = 1100/10 = 110 meters per mins

Step-by-step explanation:

So Tony's walk speed is 2 meters per minute slower then Tony's walk speed

Tony : d = 108m.....so Tony walks 108 meters per minute

Hey!! Please solve all CORRECTLY, I'm counting on you guys (i will also give brainliest and 20 points)

Answers

Step-by-step explanation:

The first one is B

x < 6 means that x cannot be 6, so only B or D works. But D is x > 6, so it's B

The second one is B

here, a filled circle means that x can be -6, so it's B or D again.

note that for these types of problems, choose a random number and see if it works. Let x = 0. Obviously, it's on the number line blue part, and it is greater than -6, so it's B

The third one is C

she has less than or equal to 45, but 45 is possible, so at most.

The last one is A. h > 4.5 means that h cannot be 4.5

So it's more, not at least.

So it's A

A I think probably a though

The points (2, 4) and (-2, -4) are plotted on the coordinate plane using the equation y = a × x. How can you use the coordinates to find the value of a?

Answers

Answer:

you can replace the y in the equation with 4 or -4 and the x with 2 or -2.

then make like all equations you want to get a by itself

right now the equation should look like 4= 2a

now you divide 4/2= 2a/2

now the equation looks like this 2=a or a=2

The value of a is 2.

Given that,

The points (2, 4) and (-2, -4) are plotted on the coordinate plane.

Based on the above information, the calculation is as follows:

Here we have to replace the y with 4 or -4 and the x with 2 or -2

So, it should be like

4= 2a

So, a = 2
