-24
-66+42
=-24 since it is negative
y= mx+b
(16, -7) = (x,y)
2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y
2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2
Insert the values into y = mx + b
solve for m and then solve for b
The answer would be Find 40% of 20 because you would round 43% down and 18 up. Hope this helps :)
Angle b will be 34 degrees because angle b and the other angle that is 34 degrees are vertical angles!
