The system of equations represented by the graph is:

y = x - 6

y + x = -2

And the solution is (2, -4), then the correct option is the first one.

<h3>What system is represented by the graph?</h3>

On the graph, we can see a system of linear equations, we can see a line with a positive slope and a line with a negative slope.

The line with a positive slope intercepts the y-axis at y = -6, then that line is:

y = a*x - 6

with a > 0.

The other line passes through the y-axis at y = -2, then the linear equation is:

y = b*x - 2

Where b < 0.

Also, remember that the solution for the system of equations is the point where the two lines intersect, so we can see that the solution is at (2, -4)

The only option that meets all the criteria is the first option:

y = x - 6

x + y = -2

And the solution is (2, -4)

Consider the exponential function f(x) = 2(3x) and its graph. The initial value of the function is
olga2289 [7]
We are given an exponential function:

f (x) = 2e^(3x)

The standard form of an exponential function is Aoe^(bx), 

where Ao is the initial value of the function
b is the growth factor of the function

To graph the function, assign values of x then solve for the values of y corresponding the values of x.

Which inequality is represented by the graph?
Taya2010 [7]

Answer:

Option B

Step-by-step explanation:

Notice that the region of the inequality is bounded by a line.

The first thing to do is find the equation of this line.

Note that the line intersects the x-axis at x = 3.5 and intercepts the y-axis at y = -2.5

We know that the equation of a line has the following form:

y = mx + b

Where m is the slope of the line and b is the intercept with the y axis.

So we already know that:

b = -2.5 = -\frac{5}{2}

Then we know that when x = 3.5 then y = 0

Thus:

0 = 3.5m -2.5

Ahroa we clear m.

m = \frac{2.5}{3.5}\\\\m = \frac{5}{7}

Then, the equation of the line is:

y = \frac{5}{7}x -\frac{5}{2}

We can also multiply by -2 both sides of the equation and we have:

-2y = -\frac{10}{7}x +5

Then:

\frac{10}{7}x -2y =5

The option that contains this equation is option B.

To verify it, enter a point within the shaded region, such as the point (0,0), in the selected inequality. If the inequality is satisfied then option B is correct

\frac{10}{7}x -2y\leq5\\\\\frac{10}{7}(0) -2(0)\leq5\\\\0\leq5

The inequality is satisfied because 0 is less than 5. Then the correct option is B
