You need to find the slope first. (-9,-4). (3,4)
-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3
Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.
The answer is - 3/2
f(a + 2) for f(x) = (3 + x) / (x - 3)
Substitute a + 2 for x in our equation
f(a + 2) = (3 + (a + 2)) / ((a + 2) - 3)
Combine like terms
f(a + 2) = (5 + a) / (a - 1).
This is as far as you can go.
C is the correct answer choice
Answer:
x > -7
Step-by-step explanation:
Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
First, subtract 15 from both sides:
-8x + 15 (-15) < 71 (-15)
-8x < 71 - 15
-8x < 56
Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:
(-8x)/-8 < (56)/-8
x < (56)/-8
x > -7
x > -7 is your answer.
