scoundrel [369]

Answer:

Total number of animals in the group = 170

Step-by-step explanation:

Let the number of sheep = a

Number of dragons in the group = 75

Number of dragons opposite dragons = 37

Number of sheep opposite to the dragon = 1

Number of sheep left = a - 1

Number of sheep opposite to sheep = $\frac{(a-1)}{2}$

Since. number of sheep opposite to sheep is 10 more than of dragons opposite dragons,

$\frac{(a-1)}{2}$ = 37 + 10

$\frac{(a-1)}{2}=47$

a - 1 = 94

a = 95

Then total number of animals in the group = Total number of sheep + Total number of dragons

= 95 + 75

= 170

Therefore, total number of animals in the group are 170.

PLEASE HELP ME ASAP!!!<br>I need help on b!!!

mixer [17]

Answer:

See below hot to plot.

Step-by-step explanation:

You did part a correctly and now have 3 points of this graph. For part b you need to plot the line by first plotting the points.

Plot the points on the graph and then connect them with a line.

The three points are (-5, -3), (0, 2), and (3, 5).

To plot (-5, -3):

Start at (0, 0), the origin, where the x-axis and y-axis intersect.

Go 5 units left to the -5. Now go 3 units down. That is point (-5, -3). Put a dot on it.

To plot (0, 2):

Start at (0, 0), the origin, where the x-axis and y-axis intersect.

Since the x-coordinate is 0, don't go right or left. Now go 2 units up to where you see a 2 on the y-axis. That is point (0, 2). Put a dot on it.

To plot (3, 5):

Start at (0, 0), the origin, where the x-axis and y-axis intersect.

Go 3 units right to the 3 on the x-axis. Now go 5 units up. That is point (3, 5). Put a dot on it.

Now connect the three dots with a line. Put arrow heads at both ends of the line.

Line n passes through the points (-3,-7.5) and (2,-5). Thalia determined that the equation of the line n is y=0.5x. Explain the

yKpoI14uk [10]

<h3>The error is -6 </h3>

Step-by-step explanation:

If a line passes through the points $(x_1,y_1)$ and $(x_2,y_2)$

Then the equation of line is

$\frac{x- x_1}{x_1-x_2} =\frac{y-y_1}{y_1-y_2}$

Here given points are (-3,-7.5) and (2,-5)

Then the equation of the line is

$\frac{x+3}{-3-2} =\frac{y+7.5}{-7.5+5}$

⇔ $\frac{x+3}{-5} =\frac{y+7.5}{-2.5}$

⇔2.5(x+3) = 5(y+7.5)

⇔(x+3)= 2(y+7.5)

⇔x+ 3 = 2y +15

⇔2y = x+3-15

⇔y = $\frac{x-12}{2}$

⇔y = 0.5 x -6

The error is -6
