The correct answer is 959,780.

In order to find this, we need to first find all the first 8 terms of the series. Each term is the previous term multiplied by -6. This gives us the following terms.

-4

-4*-6 = 24

24*-6 = -144

-144*-6 = 864

864*-6 = -5,184

-5,184*-6 = 31,104

31,104*-6 = -186,624

-186,624*-6 = 1,119,744

Now we add all those together and get our answer.

-4 + 24 - 144 + 864 - 5,184 + 31,104 - 186,624 + 1,119,744 = 959,780

A line passes through the point (-4,-5) and had a slope of 5/2. Write an equation in slope-intercept form

daser333 [38]

Step-by-step explanation:

as we have a point and the slope, we can start with the point-slope form and then transform.

the point-slope form is

y - y1 = a(x - x1)

(x1, y1) being a point on the line, a being the slope.

the slope-interceot form is

y = ax + b

a being the slope again, b being the y-intercept (the y value for x = 0).

so, we have

y - -5 = 5/2 × (x - -4)

y + 5 = 5/2 × (x + 4) = 5x/2 + 5×4/2 = 5x/2 + 10

y = 5x/2 + 5

y = (5/2)x + 5

and this is already the slope-intercept form. all done.

Which is the graph of the linear inequality x-2y> -6?<br> RII 10<br> 10- -3-²-2₂²²<br> - - - 22-

andrezito [222]

After plotting the data, we get a linear line and the right region represents the solution to the inequality.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have an inequality:

x - 2y > -6

As we can see in the inequality, there is a greater than sign, which shows at the boundary there will be a dotted line.

The x-intercept will be at x = -6

The y-intercept will be at y = 3

Thus, after plotting the data, we get a linear line and the right region represents the solution to the inequality.
