Answer:
3.207 x
Step-by-step explanation:
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)
To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

ANSWER
y = 2/3x + 15
Explanation:
Equation used: y - y1 = m( x - x1 )
y - 9 = 2/3 ( x - -9 )
y - 9 = 2/3x + 6 ( distribution )
y - 9 = 2/3x + 6 ( add 9 to 6 )
y = 2/3x + 15
Answer:
No, it is not a function
Step-by-step explanation:
Here, we want to tell if the relation is a function
For the relation to be a function, each independent variable must be mapped to only a single dependent variable
So what this means is that one term of the independent side must be mapped to one term of the dependent side
From the question, we can see that -10 and -15 were both mapped to -10 which should not be so
This means that the relation is not a function
