Answer:

B) -3

Step-by-step explanation:

1. First you have to write the equation in slope intercept form. To do that, you must have y be alone on one side.

2. move the 3x to the right side with the 5 by subtracting 3x from both sides. Since 3x will cancel on the left, y will be left alone. $y=-3x+5$

3. Now that you're in slope intercept form, you can find the slope easily. The slope will always be the number in front of x. In this case, the number in front of x is -3. Therefore, -3 is your slope!

How do I move one side to the other: <img src="https://tex.z-dn.net/?f=sin%5E2%5Calpha%20-%20cos%5E2%5Calpha%20%3D%202si

Explanation:

You can use the addition property of equality to "move" a term from one side of the equation to the other. For example, if you want to move the cos²α term, you can add cos²α to both sides of the equation:

sin²α -cos²α +cos²α = 2sin²α -1 +cos²α

When this is simplified, it becomes ...

sin²α = 2sin²α +cos²α -1 . . . . . . the cos²α term is gone from the left

The equation you have is an identity. The left and right sides are equal for any value of α. When you have such an equation as a trig problem, you are often being asked to prove it is true. The way you do that is to make use of other trig identities to transform one side so that it matches the other side.

Here, you can use the trig identity ...

sin²α +cos²α = 1

If you use this to substitute for 1 on the right, you have ...

sin²α - cos²α = 2sin²α - (sin²α +cos²α)

Now, when you collect terms, you get ...

sin²α - cos²α = 2sin²α - sin²α -cos²α . . . eliminate parentheses

sin²α - cos²α = sin²α - cos²α . . . . . proof of your identity

Answer:

Exercise Problem Solution

1 Find the perimeter of a triangle the sides of which are 10 in, 14 in and 15 in. P = 10 in + 14 in + 15 in = 39 in

2 A rectangle has a length of 12 cm and a width of 4 cm. Find its perimeter. P = 12 cm + 12 cm + 4 cm + 4 cm = 32 cm

3 Find the perimeter of a regular hexagon with each side measuring 8 m. P = 6(8 m) = 48 m

4 The perimeter of a square is 20 ft. How long is one side? 20 ft ÷ 4 = 5 ft

5 The perimeter of a regular pentagon is 100 cm. How long is one side? 100 cm ÷ 5 = 20 cm
