which equation represents the line that passes through the points (3, 7) and (-1, -1)?

Liono4ka [1.6K]

points: (3, 7) and (-1, -1)

slope (m) :

$\sf \dfrac{y_2-y_1}{x_2-x_1}$

========

$\hookrightarrow \dfrac{-1-7}{-1-3}$

$\hookrightarrow \dfrac{-8}{-4}$

$\hookrightarrow 2$

Equation:

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

==============

$\rightarrow \sf y-7 = 2(x-3)$

$\rightarrow \sf y = 2x-6+7$

$\rightarrow \sf y = 2x+1$

Which equation represents the partial sum of the geometric series?

kati45 [8]

Answer:

Option 1

Step-by-step explanation:

Given expression representing the partial sum of the geometric series,

$\sum_{n=1}^{n=4}(125)(\frac{1}{5})^{n-1}$

Expression that represents the sum of a geometric series is,

$\sum_{n=1}^{n}(a)(r)^{n-1}$

Here, n = number of terms

a = first term

r = common ratio

By comparing both the expressions,

n = 4

a = 125

r = $\frac{1}{5}$

From the given options,

Option 1

First term 'a' = 125

Common ratio 'r' = $\frac{25}{125}$ = $\frac{1}{5}$

Number of terms 'n' = 4

Therefore, Option 1 will be the correct option.

Brian has $100 in his pocket. As he is walking home 1/4th of the money falls out of his wallet. Of the remaining money, he uses

emmasim [6.3K]

Answer:

$40

Step-by-step explanation:

Brian starts at $100, then loses 1/4th of the money,

100/4 = 25,

then you subtract 25 from 100, which gives you 75

With the remaining $75, he spends $15 on girl scout cookies,

75 - 15 = 60

He then has $60 remaining, but while walking home, loses 1/3 of the total amount.

60/3 = 20,

you then subtract 20 from 60, which gives you 40

Therefore, $40 is what is remaining.
