In a particular month, Ezhil spent one-fifth of her salary on shopping. Two-fifth of the remaining she gave to her sister. If sh
Oxana [17]

Answer:

Salary = Rs23000

Step-by-step explanation:

Given

Shopping = \frac{1}{5}

Sister = \frac{2}{5}R

Left over = Rs11,040

Required

Her salary in that month

Given that she spent \frac{1}{5} of her salary on shopping, this implies that she has \frac{4}{5} of her salary left

From what's left, she gave her sister \frac{2}{5}

This means she gave her sister \frac{2}{5} * \frac{4}{5}

Sister = \frac{8}{25}

Calculating a fraction of what's left

Left over = 1 -Shopping - Sister

Left over = 1  - \frac{1}{5}- \frac{8}{25}

Left over = \frac{25 - 5 - 8}{25}

Left over = \frac{12}{25}

Recall that she has Rs11,040

This means that

\frac{12}{25} of Salary = Rs11,040

Multiply both sides by \frac{25}{12}

\frac{12}{25} * \frac{25}{12} * Salary = Rs11,040 * \frac{25}{12}

Salary = Rs11,040 * \frac{25}{12}

Salary = \frac{Rs276000}{12}

Salary = Rs23000

Hence, her salary for that month was Rs23000

What is the equation for a line that has an x-intercept of 2 and a y-intercept of -6?
USPshnik [31]

Answer:

An x-intercept of 2 implies

(

2

,

0

)

is a point on the line

A y-intercept of 4 implies

(

0

,

4

)

is a point on a line

The slope of the line joining

(

2

,

0

)

and

(

0

,

4

)

is

#(Delta y)/(Delta x) = (4-0)/(0-2) = -2

Using the slope-intercept form of the equation

y

=

m

x

+

b

where

m

is the slope and

b

is the y-intercept

we have

y

=

−

2

x

Help pls?? i have no clue what slope intercept forms are lol
Wittaler [7]

Answer:

See below.

Step-by-step explanation:

The form for slope intercept is y=mx+b, with m being the slope and b being the y-intercept.

In this case, 1/3 is the slope, and -2 is the y-intercept.

The following statements are true:

The line passes through (0,-2).

The line passes through the origin.
