Answer:
w = 4
Step-by-step explanation:
You have to switch the negative 7 into a positive, and then add it to the negative 3
-3 = w - 7
+7 +7
4 = w
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
Answer:
f(4) =0 because 4>0
f(-2) =-2 coz -2 lies between 0 and -3
f(-5) =2/-5
