C is the answer because the fractions are not proportional.
Answer: C. 9/14, 3/4
9y-8y-y= 9-8-1 = 0y =0
subtract all like terms
y = 0x - 6 has a slope of 0
If you graph several points for x where y = -6, <em>(0, -6), (1, -6), (2, -6), etc </em>you will see that it creates a horizontal line
Answer: B
The angle is 80 degrees. The measure of an angle is the exact same as the angle measure of the included arc, so that makes angle BAC 80 degrees
You gotta remember that

means

.
So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3
