The point-slope formula:
We have the points (-4, -1) and (5, 7).
Substitute:
For this one, plug in your <em>x </em> and <em>y</em> intercepts for the corresponding letters and see which one is true. I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.
Lets start with A. (4,5)
and the first equation y=x+1
5=4+1, which is true so A is a potential answer
B. (2,3)
3=2+1, B is a potential as well
C. (-2,1)
1=-2+1, which is false so C is out
D. (-4,-3)
-3=-4+1, which is true.
To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)
Answer:
600
Step-by-step explanation:
Its f(x) subtraction is the opposite of addition so you have to subtract (f-g)(x)-g(x) and if you multiply (f-g)(x) then it would be f(x) because a number times x or x by itself is x and if it was 4(x) it would be 4x parantheses means to multiply. Hope this helps!!!
