The endpoints of RS are R(–5, 12) and S(4, –6). What are the coordinates of point T, which divides RS into a 4:5 ratio?

Ksivusya [100]

Answer:

Option 2 is correct that is (-1,4)

Step-by-step explanation:

We will use the section formula to find the coordinates of T

Formula is $(x,y)=\frac{m_1x_2+m_2x_1}{m_1+m_2},\frac{m_1y_2+m_2y_1}{m_1+m_2}$

Here, $m_1=4,m_2=5,x_1=-5,y_1=12,x_2=4,y_2=-6$

On substituting the values in the formula we get

$(x,y)=\frac{4\cdot 4+5\cdot -5}{4+5},\frac{4\cdot -6+5\cdot 12}{4+5}$

$\Rightarrow (x,y)=\frac{4\cdot 4+5\cdot -5}{4+5},\frac{4\cdot -6+5\cdot 12}{4+5}$

$\Rightarrow (x,y)=\frac{16-25}{9},\frac{-24+60}{9}$

$\Rightarrow (x,y)=\frac{-9}{9},\frac{36}{9}$

$\Rightarrow (x,y)=(-1,4)$

Therefore, option 2 is correct that is (-1,4)

Answer:

5/24

Step-by-step explanation:

We have to divide 5/6 by 4.

So 5/6 divided by 4 is basically 5/6 times 1/4.

5/6 times 1/4 is 5/24

How do I have the quotient for 5 divided by 7/8

asambeis [7]

5 / 7/8 is the same as doing 5 times the reciprocal of 7/8, or
5 • 8/7.

And since 5 is really 5/1, we can just multiply the two fractions together as you would usually do.

5/1 • 8/7 = 5•8/1•7 = 40/7

Answer is 40/7
