Answer:

slope (m) = -3/2

y intercept (b) = -2

equation = y = -3/2x-2

Step-by-step explanation:

You can see that the line is negative. Using the rise/run method, you can find out the slope which is -3/2. To find the y intercept, find the point where the line crosses the y axis. Connect this info to make the equation.

The length of a violin string varies inversely with the frequency of its vibrations. A violin string 14 inches long vibrates at
lara31 [8.8K]

Answer: 525 cycles per second.

Step-by-step explanation:

The equation for inverse variation between x and y is given by :-

x_1y_1=x_2y_2       (1)

Given : The length of a violin string varies inversely with the frequency of its vibrations.

A violin string 14 inches long vibrates at a frequency of 450 cycles per second.

Let x =  length of a violin

y=  frequency of its vibrations

To find: The frequency of a 12 inch violin string.

Put x_1=14,\ x_2=12\\y_1=450,\ y_2=y in equation (1) , we get

(14)(450)=(12)(y)  

Divide both sides by 12 , we get

y=\dfrac{(14)(450)}{12}=525

Hence, the frequency of a 12 inch violin string = 525 cycles per second.

What is the vertex of the absolute value function below
Kipish [7]
The vertex is the point where the function changes direction, in this case from growing to decrease. That is the point wiht x-coordinate 4 and y-coordinate 1, so the point is (4,1).
