The answer is C. The formula for a geometric sequence is an = a1*r^n-1. If we plug in our numbers, we get an = 400*1/2^n-1. That is the same as C.
need the grid to answer qustion
Length - l
Width - w
Given,
Perimeter = 78 ft
2(l + w) = 78
l + w = 39
l = 39 - w
Given,
l = 9 + w
39 - w = 9 + w
2w = 30
--- w = 15
--- l = 39 -w = 39 - 15 = 24
Therefore, the length of the rectangle is 24 ft and width is 15 ft.
Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
y=
Answer:
y = x + 3 or y = 1x + 3
Step-by-step explanation:
Since we're just going to find the equation (assuming it's slope-intercept form, which is <em>y = mx + b</em>), our jobs will be relatively simple!
Let's start with the first step and identify the y-intercept, which is the easiest step.
That will be (0,3), as the line intercepts the y-axis there.
Next, let's find the slope of the line using or . Just be careful when using that you correctly identify the scale the axis' are using.
For now, I'll use . Let's pick two points... (0,3) and (1,4).
—> =
This will be our slope, 1.
We now have our answer, y = 1x + 3.
Hope that helped!
