Hmm, this is a tricky one. I'll do my best, though.

Well, we know that __ + __ = 36 and that one of the 2 numbers is double the other. We'll use x to be one number, and we'll use 2x to be double the number (because when you double x, you'll have 2x). And we know that we add them, right?
x + 2x = 36. Now this is making sense! Just solve it!

x+2x=36
3x=36
x=12 But don't forget, that's only the age of the younger sister. The older sister is double the age of x, or 12. What is 12 doubled? 24. 

<em>The age of the two sisters is</em><em> 12 </em><em>&</em><em> 24</em><em>.</em>

What is the equation in slope-intercept form of the line
kari74 [83]

Answer:

-5/2x+3

Step-by-step explanation:

you reciprocate the slope since you are trying to find a line perpendicular.

From this m=2/5 to -5/2

then use the formula y-y1 =m(x-x1)

then you put in the points

y - - 2= -5/2(x- 2)

y+2= -5/2x +5

-2            -2

y= -5/2+ 3
