Paul [167]

13 feet! 12 inches = 1 foot, and think of below ground as negative feet, so it’d be the difference between -1 and 12, which is 13!

Which of the following equations represents a line that passes through the points

Nonamiya [84]

Answer:

Option A is correct

A. Neither

Step-by-step explanation:

Given:

Two points are given (2, 15) and (0, 5)

Let $(x_{1}, y_{1})=(2,15)$ and $(x_{2}, y_{2})=(0,5)$

The slope of the line $m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}$

Put all known value in above equation.

$m=\frac{5- 15}{0- 2}$

$m=\frac{-10}{-2}$

$m=5$

So the slope of the line $m=5$ .

The equation of the is

$y=mx+b$ -------------------(1)

Where m is the slope of the line and b is y-intercept of the line.

Take point (0, 5) to compute the value of b.

Put $x=0,y=5\ and\ m=5$ in equation 1.

$y=mx+b$

$5=5(0)+b$

$5=0+b$

$b=5$

Take point (2, 15) to compute the value of b.

Put $x=2,y=15\ and\ m=5$ in equation 1.

$y=mx+b$

$15=5(2)+b$

$15=10+b$

$15-10=b$

$b=5$

So the equation of the line is.

$y=mx+b$

Put m and b value in above equation.

$y=5x+5$ ------------(2)

$5x-y=-5$

add 10 both side in equation 2.

$y+10=5x+5+10$

$y+10=5x+15$

$y+10=5(x+3)$

So the equation of line that passes through the point (2,15) and (0,5) is.

$y=5x+5$ or $5x-y=-5$ or $y+10=5(x+3)$

Therefore, Neither the following equations represents a line that passes through the points (2,15) and (0,5).

What is a linear equation in math?

A linear equation only has one or two variables.
No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.

Suppose, time taken by faster maid be x , hours.

So, time taken by slower maid ,

$x_{2} = 4x_{1}$ ( 4 time faster maid )

Now, time taken by both of the made together is given by ,

$( \frac{x_{1}x_{2} }{x_{1} + x_{2} } )$

$\frac{x_{1}(4x_{1} ) }{x_{1} + 4x_{1} } = 4 hours$

$\frac{4x_{1} }{5} = 4 hours$

$x_{1} = 5 hours$ which is the time required by faster maid.
