which set of steps shows the solution to the equation 2y = −8? y = −8 − 2; y = 6 y = −8 ÷ (−2); y = 4 y = −8 ÷ 2; y = −4 y = −8

xz_007 [3.2K]

Answer: The correct option is

(C) y = −8 ÷ 2; y = −4.

Step-by-step explanation: We are given to select the correct steps that shows the solution to the following equation :

$2y=-8~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

the solution to the equation $ax=b,~~\textup{a,b are real numbers}$ is given by

$ax=b\\\\\Rightarrow x=b\div a.$

Therefore, the solution of equation (i) is as follows :

$2y=-8\\\\\Rightarrow y=-8\div 2\\\\\Rightarrow y=\dfrac{-8}{2}\\\\\Rightarrow y=-4.$

Thus, (C) is the correct option.

Fine the slope of the line through each pair of points . (-8,-20),(5,2)

kozerog [31]

The formula of a slope:

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

We have the points (-8, -20) and (5, 2). Substitute:

$m=\dfrac{2-(-20)}{5-(-8)}=\dfrac{22}{13}$

Answer: The slope is $\dfrac{22}{13}$

$\sf\huge\underline\red{SOLUTION:}$

Use formula:

$\sf{V = \pi(\frac{d}{2})^2h}$

Solving for diameter:

$\sf d = 2 \times \sqrt{ \frac{V}{\pi h} } \\ \sf = 2 \times \sqrt{ \frac{40}{\pi \times 1800} } \approx0.16821 \\ = \sf \large\boxed{\sf{\green{d = 0.17}}}$

$\sf\huge\underline\red{FINAL \: ANSWER}$

$\large\boxed{\sf{\green{d=0.17}}}$
