Answer:

Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:

Combine the values:

Find the value of the fraction:

M is -3.
The equation so far is 
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
The answer would be D, because you do 4200÷56=75 minutes. 75 minutes= 1 hour and 15 minutes
(3,0) and (0,-9)
Explanation: type the equation in a graphing calculator and the answer is the points where the line crosses the x and y axis
Answer:
y=50x
Step-by-step explanation:
find the slope of the line. it goes through the origin so there is no y-intercept.

Answer:There are two right triangles. You need to find the opposite side (the height) of each of them. The difference between the two is the height of the blade, x.
You know the adjacent, 440, and you are looking for the opposite, so you need to use tan for both.
tan (30) = y / 440
y = 440 * tan (30) = 254.034...
tan (38.8) = z / 440
y = 440 * tan (38.8) = 353.769.--
353.8 - 254.0 = 99.8 = 100 feet.
