What is the equation of the line that passes through the point (-4,8) and has a slope of -1/4

iragen [17]

Answer:

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

$(y - y_1) = m (x - x_1)$

where $m$ is the slope of the line and

$(x_1, y_1)$ is the point passing through it.

Here, $m = \frac{-1}{4}$ and $(x_1,y_1) = (-4,8)$

Substituting in the equation:

$y - 8 = \frac{-1}{4} (x + 4)$

$\implies 4y - 32 = -x - 4$

$\implies x + 4y - 28 = 0$

2.77 x 10^3<br> + 1.04 x 10^4

Alex Ar [27]

2.77*10^3+1.04^10^4
2.77*10^3=2770 where (10^3=1000, so 1000*2.77)
1.04*10^4=10400 where (10^4=10000, so 10000*1.04)

2770+10400
=13170

What is the sum of the arithmetic sequence 8, 15, 22 …, if there are 26 terms?

11111nata11111 [884]

Since the sequence is arithmetic, we have an expression of the form:
$an = a1 + d (n-1)
$
Where,
a1: first term of the sequence
d: common difference
n: number of terms
We look for the common difference:
$d = 22-15 = 15-8 = 7

d = 7$
Then, setting values we have:
$a26 = 8 + 7 * (26-1)

a26 = 183
$
Then, the sum of the terms is:
$Sn = ((a1 + an) / (2)) * n
$
Substituting values:
$Sn = ((8 + 183) / (2)) * 26

Sn = 2483$
Answer:
the sum of the arithmetic sequence 8, 15, 22 is:
Sn = 2483
