Two equations are given below: m + 4n = 8 m = n - 2 What is the Solution ?

1 answer:

7 0

M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0

m=0
n=2

the answer is c. 0,2

Find the values of x for which the series converges. (enter your answer using interval notation.) ∞ (x + 9)n n = 1 find the sum

Naddika [18.5K]

If the series is

$\displaystyle\sum_{n=1}^\infty(x+9)^n$

then it is geometric, which we know converges as long as the base is smaller than 1 in absolute value, i.e. $|x+9|$ . "Expanding" the absolute value, this is equivalent to

$-1$

When $x$ is in this interval, the geometric sum converges to

$\displaystyle\sum_{n=1}^\infty(x+9)^n=\frac1{1-(x+9)}=-\frac1{x+8}$
