Answer:
m is greater than or equal to -9 the inequality sign flips when u divide by negative number
Answer:
x=5
Step-by-step explanation:
First, let's understand logarithms.
When there is no base given, like in this problem's right side of the equation, the base is automatically 10.
So, let's re-write that.

Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.

Let f(x)=0, you'll get x=3 and x=-5, those are the x-intercepts of the function.
bearing in mind that a solution to a system of equations is where their graph intersect or meets, Check the picture below.
