Answer -.3
So what I did was subtract 10-7 which is 3 then subtract 8-18 which is -10 then divide 3 divide by -10 and you get -.3
Find 3/4 of 16.
16 * 3/4
48/4
12

Answer: the second option is the correct answer
Step-by-step explanation:
The given expression is
[3/(x - 1) - 4]/[2 - 2/(x - 1)
We would simplify the numerator first. The LCM of the numerator is
x - 1. Taking the LCM of the numerator, it becomes
[3 - 4(x - 1)]/(x - 1)
= [3 - 4x + 4]/(x - 1)
= (- 4x + 7)/(x - 1)
We would simplify the denominator. The LCM of the denominator is
x - 1. Taking the LCM of the numerator, it becomes
[2(x - 1) - 2]/(x - 1)
= [2x - 2 - 2]/(x - 1)
= (2x - 4)/(x - 1)
= 2(x - 2)/(x - 1)
The expression becomes
[(- 4x + 7)/(x - 1)]/[ 2(x - 2)/(x - 1)]
= (- 4x + 7)/(x - 1) × (x - 1)/2(x - 2)
(x - 1) cancels out. It becomes
(- 4x + 7) / 2(x - 2)
trigonometric functions state that cosine functions are even so that automatically rules out the first two options.
sine functions are odd so the last two are right.
odd functions: f(-x)=-f(x)
so the sine would be: sin(-x)=-sin(x)
the third option should be the right answer
(y2-y1)/(x2-x1)
(-7-5)/(4-2)
-12/2= -6
