Answer:
C
Step-by-step explanation:
to find the value of the constant at the end of the equation, look for where the line meets the y-axis (here it is +1). Since all of the answer choices have 4 as a slope, looking to see if the line is going down or up will tell you if it's -4 or +4. (here it is negative)
Answer:
A
Step-by-step explanation:
First you simplify both sides to get -2.4x+14.4 > 52.8
then you need to subtract the 14.4 from both sides giving -2.4x> 38.4
then divide both sides by -2.4 giving an answer of
x is less than or equal to -16 meaning you point to the left with a closed circle

Answer:
divide by x
Step-by-step explanation:
To answer your question, you can get from A to B by dividing by x:

However, this is only a valid operation if x ≠ 0. In this equation, x = 0, so that division is not valid.
__
A better approach to the solution is to put the equation in standard form:
f(x) = 0
You can get there by subtracting 3x from both sides.
5x -3x = 3x -3x
2x = 0
Now, you can legitimately divide by 2 to find ...
x = 0 . . . . . . . . the reason why dividing by x is not allowed
