Answer:
its A
Step-by-step explanation:
15. -6b+2-5b=36+6b
-11b+2=36+6b
-17b+2=36
-17b=34
b=-2
16. 48+32h=-39+3h
48+29h=-39
29h=-87
h=-3
17. -20r+5=-20r+20
5¥20
no solution
18. a+7=7a+21+18-6a
a+7=a+39
7¥39
no solution
19. -8b+24=24-24b
16b+24=24
16b=0
b=0
20. 5a+4=5a-10
4¥-10
no solution
Basically you multiply the probabilities
So 92/100 * 92/100 = 0.8464 so around 84-85%
Refrection over the x-axis changes |x| to -|x|.
Vertical stretch by a factor of 2.5 changes the function to -2.5|x|
Shifting the function down by 3 units changes the function to -2.5|x| - 3
Therefore, f(x) = -2.5|x| - 3
