Which of the following is equal to the expression listed above?

MA_775_DIABLO [31]

Answer:

$(14 + 7) + 12 = 14 + (7 + 12)$

Step-by-step explanation:

Given

$(14 + 7) + 12$ --- [Missing in question]

Required

Select equivalent expression

$(14 + 7) + 12$

Associative property states that:

$(a + b) + c = a + (b + c)$

In this case:

$a = 14$

$b = 7$

$c = 12$

So, we have:

$(a + b) + c = a + (b + c)$

$(14 + 7) + 12 = 14 + (7 + 12)$

B. is correct

Find the slope of the line passing through the points (-5, 3) and (7,9).

dybincka [34]

Answer:

$\huge\boxed{slope=\dfrac{1}{2}=0.5}$

Step-by-step explanation:

The formula of a slope:

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

We have the points

$(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9$

Substitute:

$m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}$
