Determine the slope of the line that contains the points A(0, 2) and B(7,3). *

IgorC [24]

<h3>Given points:-</h3>

A (0,2)
B (7,3)

We know that

${\boxed{\sf Slope_{(m)}=\dfrac {y_2-y_1}{x_2-x_1}}}$

Substitute the values

$\qquad\quad {:}\longrightarrow\tt m=\dfrac {3-2}{7-0}$

$\qquad\quad {:}\longrightarrow\tt m=\dfrac {1}{7}$

$\therefore \sf Slope\:of\:the\:line\:is\:\dfrac {1}{7}$

-1/4d-2/5d=39 Solve for d Please explain I don’t understand

Papessa [141]

Given:

The equation is

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

To find:

The value of d.

Solution:

We have,

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

Taking LCM, we get

$\dfrac{-5d-8d}{20}=39$

$\dfrac{-13d}{20}=39$

Multiply both sides by 20.

$-13d=39\times 20$

Divide both sides by -13.

$d=\dfrac{39\times 20}{-13}$

$d=-3\times 20$

$d=-60$

Therefore, the value of d is -60.
