Answer:
y = - 1/2x + 5
Step-by-step explanation:
y = 2x – 6 slope = 2
Perpendicular line slope = -1/2
for (4 , 3) y = mx + b y = 3, x = 4, m = -1/2
b = y - mx = 3 - (-1/2) x 4 = 5
equation: y = - 1/2x + 5
Answer:
B. No the ordered pair does not satisfy the equation
Step-by-step explanation:
y = -9x - 2
Substitute the point in and see if it is true
-37 = -9(4) -2
-37 = -36 -2
-37 = -38
This is not true so the point is not a solution
I suppose a DJ wants to select 4 different songs, then there are: 12*11*10*9 = 11880 ways to choose them.
If the order of the songs he plays doesn't matter, there are: 
ways to choose them.
C. 6,9,12 I hope this helps! :)
The answer is 290. First calculate the area of the rectangle part on the bottom. area=20*9=180 square yards. Then calculate the area of the triangle on the top. Base length is 20, while the height is 20-9=11, so the area is 20*11/2=110. 180+110=290 square yards in total.
