D.) No solution

2x - 3 = 2x -5

That is because it they were to be equal to each other it would be either

2x - 3 = 2x - 3 or

2x - 5 = 2x -5

- 3 cannot be equal to -5

2x is in both the equation so they cannot be equal to each other

2x -2x - 3 = 2x - 2x - 5        <em>subtract 2x from both sides</em>

-3 = -5    FALSE

.......... is the slope zero
Eddi Din [679]

Answer:


Step-by-step explanation:

OK... You have to use this formula: <u>Y2 - Y1</u>

                                                          X2 - X1

  • -2 represents X1
  • 7 represents Y1
  • 2 represents X2
  • -5 represents Y2    

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 7</u>

2 - - 2

<u>-12</u>

-2

Simplify by dividing both -12 & -2 by 2: <u>-6</u>

                                                                 -1

It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...

                -1

A nurse collected data about the average birth weight of babies in the hospital that month. Her data is shown using the dot plot
mixer [17]

Answer:

The values of the box-plot are: B = {8.2, 8.3, 8.4, 8.5 and 8.9}.

Step-by-step explanation:

The data provided is as follows:

X     Frequency

8        0

8.1        0

8.2        2

8.3        2

8.4        2

8.5        3

8.6        0

8.7         1

8.8        0

8.9         1

 9           0

So, the actual data is:

S = {8.2 , 8.2 , 8.3 , 8.3 , 8.4 , 8.4 , 8.5 , 8.5 , 8.5 , 8.7 , 8.9 }

A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,

  1. Minimum (shown at the bottom of the chart)
  2. First Quartile (shown by the bottom line of the box)
  3. Median (or the second quartile) (shown as a line in the center of the box)
  4. Third Quartile (shown by the top line of the box)
  5. Maximum (shown at the top of the chart).

The data set is arranged in ascending order.

The minimum value is, Min. = 8.2

The lower quartile is,

[\frac{n+1}{4}]^{th}\ obs.=[\frac{11+1}{4}]^{th}\ obs.=3^{rd }\ obs. =8.3,

Q₁ = 8.3.

The median value is,

[\frac{n+1}{2}]^{th}\ obs.=[\frac{11+1}{2}]^{th}\ obs.=6^{th}\ obs.=8.4

Median = 8.4

The upper quartile is,

[\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(11+1)}{4}]^{th}\ obs.=9^{th }\ obs. =8.5,

Q₃ = 8.5.

The maximum value is, Max. = 8.9.

So, the values of the box-plot are: B = {8.2, 8.3, 8.4, 8.5 and 8.9}.

Fill in the missing value for Y,<br> then click DONE.<br> y = 2x + 3
BARSIC [14]

Answer:

x = 2 so y = 7

x = 4 so y = 11

Step-by-step explanation:

y = 2x + 3

x = 0 so y = 2(0) + 3 | y = 3

x = 2 so y = 2(2) + 3 | y = 7

x = 4 so y = 2(4) + 3 | y = 11

x = 6 so y = 2(6) + 3 | y = 15
