Answer:
n = 2
Step-by-step explanation:
Expand the brackets.
1/2n - 2 - 3 = 3 - 2n - 3
Add or subtract terms.
1/2n - 5 = -2n
Add 5 and 2n on both sides.
1/2n + 2n = 5
5/2n = 5
Multiply both sides by 2/5.
n = 5 × 2/5
n = 10/5
n = 2

Write in slope-intercept first.
Find the y-intercept.
y = -2x + b
3 = -2(4) + b
3 = -8 + b
3 + 8 = -8 + b + 8
11 = b
Now, write in slope-intercept form.
y = -2x + 11
Now, solve for standard form.
y - 11 = -2x + 11 - 11
y - 11 = 2x
y + (-11) - y = -2x - y
-11 = -2x - y
-2x - y = -11 (Answer)

the simplification just ends up being the original equation.
an explicit formula for the arithmetic sequence -5,13,31,49 is .
<u>Step-by-step explanation:</u>
Here we have an arithmetic sequence -5,13,31,49 . We need to find an explicit formula for the arithmetic sequence .Let's find out:
Let be terms of an A.P , common difference is :
⇒
⇒
⇒
⇒
We know that general term of an Arithmetic Progression ( A.P) is :
⇒
So , Here we will have
⇒
⇒
⇒
Therefore , an explicit formula for the arithmetic sequence -5,13,31,49 is .
