Answer:

Addition

Step-by-step explanation:

Since you are trying to make x the subject, you need to "get rid" of the -2. So, because it is a negative number, you add 2 to make it 0, which is added to both sides, making x = 7.

Hope this helps!

The answer should 7, because you need to add 2 to both side in order to solve for X. So addition would be the operation.

What is the slope OF THE GRAPH, not what is A slope, what is THE slope

Oksanka [162]

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.) It's 1.

Rise/Run = -3/1 AKA -3

The graph of y=3x^2-3x-1 is shown. Use the graph to find estimates for the solutions of i)3x^2-3x+2=2 ii) 3x^2-3x-1=x+1

AlexFokin [52]

Answer:

i) (0, 2) and (1, 2), ii) (0.333, 1.333) and (1, 2).

Step-by-step explanation:

i) Let be $y=3\cdot x^{2}-3\cdot x -1$ , if $3\cdot x^{2}-3\cdot x +2 = 2$ , which is equivalent to the following system of equations:

$y = 3\cdot x^{2}-3\cdot x +2$

$y = 2$

Now, this system is now represented by means of a graphing tool and whose outcome is attached below. There are two solutions: (0, 2) and (1, 2)

ii) Let be $y=3\cdot x^{2}-3\cdot x -1$ , if $3\cdot x^{2}-3\cdot x +2 = x+1$ , which is equivalent to the following system of equations:

$y = 3\cdot x^{2}-3\cdot x +2$

$y = x+1$

Now, this system is now represented by means of a graphing tool and whose outcome is attached below. There are two solutions: (0.333, 1.333) and (1, 2)
