(3) 8

Step-by-step explanation:

Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.

BC/AB = DE/AD

BC/10 = 12/(10 + 5) = 12/15 = 4/5

or

BC = 10(4/5) = 8

–34 = –2(g − 70) g = _____
olganol [36]

━━━━━━━☆☆━━━━━━━

▹ Answer

<em>g = 87</em>

▹ Step-by-Step Explanation

-34 = -2(g - 70)

<u>Rearrange the terms</u>

-g + 17 = 70

<u>Calculate</u>

-g = -87

<u>Change the signs</u>

g = 87

<u>Final Answer</u>

g = 87

A line has a slope of –3 and a y-intercept of (0, –1). What is the equation of the line that is parallel to the given line and p
givi [52]
Well, the first line has a slope of -3, and runs through 0, -1.

a line parallel to that one, will have the same exact slope of -3.

now, we know about this other parallel line that it runs through -3,1, and of course, since is parallel, it has a slope of -3

\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1\\&#10;&&(~ -3 &,& 1~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies -3&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-1=-3[x-(-3)]&#10;\\\\\\&#10;y-1=-3(x+3)&#10;\implies &#10;y-1=-3x-9\implies y=-3x-8
