as the ray divide the right angle into 2
Answer:
A bit of a doosy, but bare with me: f*g*h(x) =
Step-by-step explanation:
So explaining this is a bit awkward as well, but I can try...So
Starting from g(x) working that backwards into f(x), so...
g(x) =
f(x) =
Take your g(x) and plug it into your f(x) into every x you see
f(g(x)) = ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...
Now you still have one more step which you still need to include h(x), so
Remember h(x) =
Now plug in your h(x) into every x you see from f(g(x)) and it should look like...
Slope is 0. y-intercept is (0, 4/5)
Answer:
The answer to your question is (1, -2)
Step-by-step explanation:
See the graph below, in the graph, the solution is circled (1, -2). The solution is the point where the lines cross.
To check the answer, let's solve the system using algebra.
y = 2x - 4
y = 1 - 3x
2x - 4 = 1 - 3x
2x + 3x = 1 + 4
5x = 5
x = 5/5
x = 1
Find y by substitution
y = 2(1) - 4
y = 2 - 4
y = -2
Solution
(1, -2)
