Answer:

Opt. B

Step-by-step explanation:

The key feature is to eval x in a point where |x| is zero, since the vertex of the function is located at that point.

|x|=0 means that y=-4.

Hence the vertex of this point is located at (0,-4)

4 Units down if we compare with the parent function y=|x|

Here is the math, did it on paper, sorry it’s blue. just add parenthesis around the x in the second equation and add what x equals. then solve as PEMDAS.

Someone know how to do this?: 6x2+18x=0

Crazy boy [7]

The answer to the question is: Yes.

Explanation: It can be solved by following exactly the same procedures
that solved the other two questions that you posted within the past 15 minutes.

Since I'm here already, here is the solution to this one:

6x² + 18x = 0

Divide each side of the equation by 6 :

x² + 3x = 0

Factor the left side:

x(x+ 3) = 0

This statement is true if x=0 or if x=3.

The solution to this one is even the same as the solution to the last one you posted.
You really ought to take a break, go back, review the solutions you've been given,
and try to solve a few on your own.

Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in s

Answer:

y = -0.2x - 5.8

Step-by-step explanation:

If a line is given in the form y = mx + b, the "m" is the slope.

For the line given y = 5x, the slope is 5

The line that is perpendicular to this will have slope that is "negative reciprocal of that".

So, the perpendicular line will have slope of $-\frac{1}{5}$
