How many Solutions are there for -6(3x+2)=2x-5-20x-7
1 answer:
First of all, expand the left hand side:
Sum like terms on the right hand side:
As you can see, the equation turned to be an identity: it doesn't matter which value for x you are choosing: you're evaluating the same expression in both sides, so they will always be the same.
In other words, you're asking: which value for x should I choose so that -18x-12 and -18x-12 evaluate to the same number? Well, obvisouly any value for x will do.
So, there are infinitely many solutions to this equation, namely ever real number is a solution of this equation.

Answer:
Predicted Rotten Tomatoes Score = 29.476 + 1.201 * Metascore
Step-by-step explanation:
The image is needed to solve it, I found an image that I think would be the one that adapts to the exercise, which I will attach.
The answer is:
Predicted Rotten Tomatoes Score = 29,476 + 1,201 * Metascore
Because if we follow the red line, we can see that it impacts with the axis of the and a little lower than 30, that is to say that when Metascore is 0, the value must be close to 30 and in this case the only value close to 30 inside the answer is 29,476, so this is the answer.
Answer:
Approach 1: Mathematical Approach
Domain is the possible inputs or x values of a function
Here we can use any x values greater than or less than 7. We can also use 7 since their is a a function defined for x greater than or equal to 7.
So the domain is (-♾, ♾).
The range is possible y values. Since we can use negative x values, if we plug in x values for the function -5/7x+1, we are going to get positive numbers, as we plug in higher negative numbers, our range is bigger.
This means the range is bounded to -4 so our range is
(-4,♾)
Approach 2: Graphical Approach
Above is the graph
It can take any x values so the domain is (-♾, ♾).
The range is (-4,♾).
