Answer:
- cos (x) cos (2x) - 2sin(x) sin(2x)
Solution:
(See the solution in the photo)
Yes, because there are common factors in the equation. therefore showing you can group
Answer:
y=3/2x+5
The slope is 3/2 and the y-intercept is 5
Step-by-step explanation:
Solving for y will give us the slope and y-intercept
Isolate y
2y/2=10+3x/2
y=5+3/2x
The slope is 3/2 and the y-intercept is 5
Graph it by graphing (0,5) and using the slope (up 3 over 2) to put other points
slope intercept form: y=mx+b
y=2x-3
slope is also m
b is the y-intercept
answer:
slope is 2
y-intercept is -3
Two times the sum of a number and nine.
