2) Equation would be: y = -3x
As it is not in exponent, direct in mutilication, it is directly proportional

3) Equation: y = 2x
It is directly proportional

4) Equation: y = x - 5
Here, it is not directly proportional.

5) Equation: y = 1.5x
Again., It is directly proportional

Hope this helps!

30 points if you can answer this question and tell me how to do it

vlabodo [156]

Answer for a)

Since the coordinates are arranged as (x, y, z), then 3 would be for x, 0 would be for y, and 1 would be for z. The x is the length, the y is the height, and the z is the width. It is said that the x-axis value is 3 so there are 4 letters on the 3 value which are: P, S, B, and A. Now, let's look at the 0 on the y-axis. Since the y-axis is the height, then there are 2 letters remaining: A and B. Now, the z-axis is 1. So the letter for point (3, 0, 1) is... B.

Answer for b)

For the x-axis, P is at 3. For the y-axis, P is at 2. For the z-axis, P is at 1. So the coordinate of P is: (3, 2, 1).

If tan 0 = 12/5 and cos 0 = - 5/13 then what is sin 0

slamgirl [31]

Refer to the diagram shown below.

Because tan θ = 12/5 and cos θ = -5/13, therefore θ is in quadrant 3.
The sine function is negative in quadrant 3, therefore
sin θ = - 12/13

Answer: - 12/13

Which expression uses the commutative property to make it easier to evaluate

Basile [38]

Let's begin by listing out the given information:

The commutative property states that for addition, the order in which we add numbers does not change their sum & for multiplication, the order in which we multiply does not change their product.

Mathematically expressed as:

$\begin{gathered} x+y+z=y+z+x \\ x\cdot y\cdot z=y\cdot z\cdot x \end{gathered}$

Therefore, the commutative property of this is:

$\begin{gathered} \frac{4}{3}\cdot\frac{1}{5}\cdot18=\frac{4}{3}\cdot18\cdot\frac{1}{5} \\ \Rightarrow\frac{4}{3}\cdot18\cdot\frac{1}{5} \\ \end{gathered}$

Therefore, Option D is the correct answer

1. What is the slope of this line?<br><br>(have this done correctly for brainiest)

expeople1 [14]

Answer:

Step-by-step explanation:

slope = dy/dx

We can see a dy (delta y) of 4 together with a dx of 1. In other words, when you step 1 to the right, you go up 4.
