To fine the mean for a first add up all the players heights then divide by the number of players.

Mean=(198+199+200+201+202)÷5
=1000÷5
=200

The answer to a is 200

For question be were gonna say for now that the height of our new player is represented by x. So we know that together there is 6 players and we know our answer so it should look something like this

201= (199+198+199+200+201+202+x) ÷ 6
201=1000+x ÷ 6
Then Im going to multiply 201 by 6 to get rid of the 6 on the other side.
1206=1000+x
Then I’m going to subtract 1000 from both sides to get x by itself
206=x

So the new players height is 206 .

Correct I’ll give brainlist no links or I’ll report

GaryK [48]

Answer:

y = 5x -23

Step-by-step explanation:

Alright, for this, we need the slope and the y intercept. First, the slope.

So to find the slope, find any two points that the line goes over first. For example, the dotted point (5,2). Now for the other one, (4,-3) can be used.

Look for when the line is crossing over the points of the square graph, as this will help you with the next part.

For the next part, to find the slope, this is going to see how much the line has done up/down for how much we move forward or backwards on the line. With this, the equation:

y2-y1 / x2-x1 can be used, with the 2s and 1s being just to show that there are 2 separate points being used for it.

Next, plug it in with what's known:

2-(-3) / 5-4

5 / -1

Slope is 5.

Now, the y intercept needs to be found. To get this, we need the y value for where the line passes over where the x value is 0.

By knowing that the slope is 5, we can walk backwards to the y intercept to get this value. With this, for every number in x walked back, it will go down 5 y values:

5, 2 (Do -1, -5)

4, -3 (Do -1, -5)

3, -8 (Do -1,-5)

2, -13 (Do -1,-5)

1, -18 (Do -1,-5)

0, -23 (All done)

The y intercept is now found, along with the slope. Now these values can be both be plugged into the slope intercept equation, y=mx+b, where m is for the slope and b is where the y intercept goes.

y = 5x -23

Solve for X

Tresset [83]

Answer: x = 0

Step-by-step explanation: To solve for <em>x</em> in this equation, our first step is to simplify the left side by distributing the 10 through both terms inside the parentheses.

When we do that, we get 10 times x which is 10x

and 10 times -2 which is -20.

So we have 10x - 20 = -20.

Adding 20 to both sides, we get 10x = 0.

Divide both sides by 10 and <em>x = 0</em>.

Which equation does the graph of the systems of equations solve? 2 linear graphs. They intersect at 0,3

Rainbow [258]

Answer:

D. $2x+3=-8x+3$

Step-by-step explanation:

We have been given a graph of system of linear equations and we are asked to choose the system of equations representing the given graph.

Upon looking at our graph we can see that our lines intersect at point (0,3). To find the system of equations represented in the graph we will substitute x=0 in our given equations and see which equation gives us an output of 3.

Let us start with 1st option.

A. $-2x+3=8x-3$
