What is the value of the numerical expression 5/8 - 5/12 (3 -1/4) + 2/3 ?

nasty-shy [4]

$\dfrac{5}{8} - \dfrac{5}{12} ( 3 - \dfrac{1}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (2\dfrac{3}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{5}{12} (\dfrac{11}{4} )+ \dfrac{2}{3}$

$= \dfrac{5}{8} - \dfrac{55}{48}+ \dfrac{2}{3}$

$= \dfrac{30}{48} - \dfrac{55}{48}+ \dfrac{32}{48}$

$= \dfrac{7}{48}$

A line passes through the points (2,4) and (5,6) .

Alenkinab [10]

Answer:

Option B and D are correct.

Step-by-step explanation:

Given: A line passes through the points (2,4) and (5,6).

* Case 1:

If a line passes through the points (2, 4) and (5, 6)

Point slope intercept form:

for any two points $(x_1,y_1)$ and $(x_2, y_2)$

then the general form $y -y_1=m(x-x_1)$ for linear equations where m is the slope given by:

$m =\frac{y_2-y_1}{x_2-x_1}$

First calculate slope for the points (2, 4) and (5, 6);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{6-4}{5-2} = \frac{2}{3}$

then, by point slope intercept form;

$y-4=\frac{2}{3}(x-2)$

* Case 2:

If a line passes through the points (5, 6) and (2, 4)

First calculate slope for the points (5, 6) and (2, 4);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-6}{2-5} = \frac{-2}{-3}= \frac{2}{3}$

then, by point slope intercept form;

$y-6=\frac{2}{3}(x-5)$

Yes, the only equation of line from the given options which describes the given line are;

$y-4=\frac{2}{3}(x-2)$ and $y-6=\frac{2}{3}(x-5)$
