Answer:
68
Step-by-step explanation:
Draw a line from(-4,3) to (4,3).
a square and triangle is shown.
find the area of the square and the triangle
FORMULA
<em>square-length*width</em>
<em>7*8=56</em>
<em>triangle-(hight*base)/2</em>
<em>(8*3)/2=12</em>
56+12=68
Given:
15 students
2 students must be chosen.
No repetition, no order
This is a combinations problem. We use this formula: n! / (n-r)!(r!)
n = 15 ; r = 2
15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105
6x – 4y = 9
4y = 6x - 9
y = 6/4 x - 9/4
y = 3/2 x - 9/4 this line has slope = 3/2
perpendicular line, slope is opposite and reciprocal so slope of this line = -2/3
answer:
A. y= - 2/3 x - 4 (only this line has slope = -2/3)
