Tell me the y-intercept of the line: 2x - 3y = 9
butalik [34]

Answer:

y-intercept: (0,-3)

Step-by-step explanation:

  • Y-intercepts mean that the x-value has to be equal to 0. When plugging in 0 for the x-value, we receive:

  • 2(0)-3y=9\\0-3y=9\\-3y=9\\y=\frac{9}{-3} \\y=-3

  • Therefore, the point is (0,-3).

A certain jet can reach an altitude of 8000 ft while flying 16000 ft through the air. what is the angle of the elevation that th
irina1246 [14]

Answer:

27 degrees

Step-by-step explanation:

First, we can draw this out. Since the altitude is 8000, we can make that the height, and it goes 16000 feet through the air, that can be the length. I have drawn this out, as shown in the image. Note that when drawing, because the airplane is going up and forward, that path should represent the hypotenuse. The angle of elevation is the angle connecting the length and the path, as shown by the angle x in the picture.

We know than tan(x) = opposite/adjacent, so tan(x) here = 8000/16000 = 1/2. Then, arctan(1/2) =x = 27 degrees
