Hello there!
First, we need to know when do we have a linear equation.
<span>"A linear equation is an equation between two variables that gives a straight line when plotted on a graph."
I am honestly not good with graphing these kind of equation, so I usually used an online graphing to help me.
Remember we have a linear equation when we have straight line.
Graph the first equation(see picture 1) Y = 4/x + 3
Answer: No, it is not a linear equation. As you can see the lines are not straight. Got it? I hope so :)
P.S Unfortunately, I am not sure what is happening but I can load the pictures of the graph. So here is the link to the graph for the first equation.
Now let's work with the second equation y = -2x - 4
Answer: Yes it is a linear equation. Why? Because the line is straight. See this link for the graph.
I tried my best, I hope you understand and if you have questions, just let me know.
As always, I am glad to be your helper!

The opposite of something means to change this signed that is with the number.
If it is a positive number, the opposite would be negative.
So in this example, if it's the opposite of positive 5, that is -5. The opposite of -5 would be positive 5.
The equation that shows this correctly would be D.
Answer:
132
Step-by-step explanation:
12 times 11= 132 PLEASE MARK BRAINLIEST
After the 15% discount, Maria pays 85% of the cost. That cost is the sum of the fixed cost and the variable (per visit) cost.
... (updated cost) = 0.85×($150 +$30×a)
... (updated cost) = 127.50 +25.50a . . . . in dollars
0.6 would be the same as $0.60 AKA 60 cents and 0.06 would be the same as 6 cents
