Answer:
Step-by-step explanation:
This is one of those things that will drive you insane until you understand the answer.
Every y value is 4 no matter what x is.
The perpendicular will meet y = 4 at the point (6,4)
Answer: So the equation has to be x = 6.
The blue line is y = 4
The red line is x = 6
The point of intersection is marked.
Answer:
Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as
Answer:
D. 4
Step-by-step explanation:
Without actually solving the equation, recall that for , there are two cases:
In the given equation , there are two pairs of absolute value symbols.
Since each has two cases, there must be a total of different equations created.
All four cases are:
Exponents differ, hence clearly there are four possible solutions to this equation.
You can solve for all four values of by taking the log of both sides and using a bit of algebra to verify you have four solutions.
