Answer:
Step-by-step explanation:
y - 4 = -7(x - 0)
y = -7x + 4
Answer:
(x, y) = (0, -2248)
Step-by-step explanation:
<u>Substitution</u>
Substitute for y:
300x -2248 = 350x -2248
0 = 50x . . . . . . . . add 2248-300x to both sides
x = 0
y = 300·0 -2248
The solution is (x, y) = (0, -2248).
__
<u>Elimination</u>
Subtract the first equation from the second.
(y) -(y) = (350x -2248) -(300x -2248)
0 = 50x
x = 0
y = 300·0 -2248
The solution is (x, y) = (0, -2248).
__
<em>Additional comment</em>
If you think for a bit about what the graph looks like, you realize both lines cross at their y-intercept, (0, -2248). That point of intersection is the solution to the system of equations.
Answer: 19.47°
Step-by-step explanation:
In solving problems like this, it's best to work on a diagram (see attached image). First, given the angle formed by the ramp and the length of the ramp, we can apply the properties of right triangles and recall that
Hence, we have
Now that we have the window's height, we can compute for the angle, θ, if the ramp has a length of 15.
Therefore, for the 15-foot ramp to reach the window, the ramp must form an angle of 19.47°.
Answer: 19.47°
