a snowplow has maximum speed of 40 miles per hour on a dry highway. It's maximum speed decreases by 1.2 miles per hour for every

inch of snow on the highway. According to this model, at what snow depth will the snow plow be unable to move?

8 0

Step-by-step explanation:

The snowplow's speed is 40 mph minus the loss from the snow, which is 1.2 mph times the depth of snow in inches.

y = 40 − 1.2x

When y = 0:

0 = 40 − 1.2x

1.2x = 40

x = 33 ⅓

The snowplow stops moving when the snow is 33 ⅓ inches deep or more.

What is the domain and range of the following graph?
puteri [66]

Using it's concepts, the domain and the range of the graph are given as follows:

  • Domain: all real values except x = -1.
  • Range: All real values.

<h3>What are the domain and the range of a function?</h3>

  • The domain of a function is the set that contains all the values of the input. In a graph, it is given by the values of x, which is the horizontal axis of the graph.
  • The range of a function is the set that contains all the values of the output. In a graph, it is given by the values of y, which is the vertical axis of the graph.

In this graph, have that the function is defined for all values of x except x = -1, and assumes all real values, hence the domain and the range of the graph are given as follows:

  • Domain: all real values except x = -1.
  • Range: All real values.

Katrina wrote the standard form of a linear equation as 4x-2/3y=8. Sophia told her that the equation was not yet in standard for
Angelina_Jolie [31]

9514 1404 393

Answer:

  multiply by 3 and divide by 2 to get 6x -y = 12.

Step-by-step explanation:

A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...

  4(3/2)x -(2/3)(3/2)y = 8(3/2)

  6x -y = 12
