Answer:

Hope this helps

Step-by-step explanation:

Page 1:

I'm not sure about the first page but here is what I think.

Increased by a value of 3.

Figure 0, is most likely 2 blocks.

Starting value = 2

Growth = 3

y= 3x + 2

Fill in the values to get y.

For example, 3(52) + 2

The rate of change is 3

The y - intercept is 2

The equation of the line is y= 3x + 2

Page 2:

I assuming that the y-intercept is -5 considering it is with 0.

Looking at 10 I see 25. What times 10, subtracted by 5 will get you 25?

3

So I assume that the equation is 3x - 5. Apply this equation to 6 and 0 to see if it is correct.

3(6) - 5 = 13. Now apply this to the other values to get the rest of the chart.

Not sure what the x means in the last input

Red Line

<em>Slope:</em> 3

<em>y-intercept:</em> 4

<em>Equation:</em><em> </em>y = 3x + 4

Blue Line

<em>Slope: </em> (-1/3)

<em>y-intercept: </em>-4

<em>Equation: </em>y = (-1/3) - 4

Two congruent right triangles with sides of 3, 4, 5 are placed together so that one pair of corresponding sides touch and the re
Rom4ik [11]
It depends on which pair of the sides are touched.. if the 4s are touched then the perimeter would be 5+5+3+3=16, if the 3s are touched then the perimeter would be 5+5+4+4=18 but if the 5s are touched then it becomes a rectangle so that's irrelevant

Svetradugi [14.3K]

13 years

Step-by-step explanation:

17 + 15 + 23 + 23 + 23 =101 / 5 = 20.2

Mean before was 20.2

In order for the mean to be 19, all those numbers would have to add up 114 to be divided by 6 and have a mean of 19

114 / 6 = 19

114-101 = 13 is that number

17 + 15 + 23 + 23 + 23 + 13 = 114 / 6 = 19
