When hav epoins (x1,y1) and (x2,y2)
slope is  (y2-y1)/(x2-x1)

(-3,4) and (5,-1)
slope=(-1-4)/(5-(-3))=-5/(5+3)=-5/8

slope=-5/8

Tony Owens a special pet store that sells only snacks and elephants currently he has a total of 11 snacks and elephants in stock
bagirrra123 [75]

Answer:  There are 8 snake and 3 elephants.

Step-by-step explanation:

Let x= Number of snakes

y= Number of elephants

We know that , snake has no legs elephant has 4 legs.

Then, Total animals = x+y=11  (i)

Total legs = 4y = 12

⇒ y=3   .. (ii)[divide both sides by 4]

Substitute value of y from (ii) in (i) , we get

x+3=11\Rightarrow\ x=8

Hence, there are 8 snake and 3 elephants.

Find the measure of the angle indicated in bold
GuDViN [60]

Answer:

3/2 =x

Step-by-step explanation:

These two angles are interior angles.  They add up to 180 degrees

20x+5 = 24x-1

Subtract 20x from each side

20x-20x+5 = 24x-20x-1

5 = 4x-1

Add 1 to each side

5+1 =4x-1+1

6 =4x

Divide by 4

6/4 = 4x/4

3/2 =x

Wendy is standing 60 feet away from a tree. Her eyes are 5 feet above the ground. She sees a bird hovering above a tree. The ang
Gennadij [26K]

The bird is 17 feet above the tree.

<u>Explanation:</u>

We need to think of this in terms of right triangles.  If Wendy is 60 feet from a tree, the base of the right triangle is 60 feet.  The height of the tree is the height of the right triangle.  The angle of elevation is the one from the ground at her feet to the top of the tree and then to the bird.  Let's start with the top of the tree first.

She's 60 feet away, we have the angle of elevation as 25 degrees, and we are looking for the height of the tree.  In regards to the angle, the base of 60 is adjacent, and the height of the tree is opposite.  The tangent ratio is height / base.

Let x be the height of the tree.

So,

tan (25) = \frac{x}{60}

60 tan(25) = x\\\\x = 27.9 feet

x is approximately 28 feet

Since, Wendy's eyes are 5 feet above the ground, the height of the tree becomes

28 + 5 = 33 feet

<u>For bird</u>

Let y be the height of the bird in the air

tan(37) = \frac{y}{60} \\\\60 tan(37) = y\\\\y = 45.2 feet

y is approximately 45 feet

Since, Wendy's eyes are 5 feet above the ground, the height of the tree becomes

45 + 5 = 50 feet

To know how far above the tree that bird is

50 - 33 = 17 feet

Therefore, the bird is 17 feet above the tree.
