Answer:
The answer is C
Step-by-step explanation:
Z is 150.
Because you have to cross multiply so, 6*100=600 then 600 divided by 4 equals 150. Z=150
I hope this helps☺️
6-by=19
minus 6 from both sides
-by=19-6
-by=13
divide both sides by -b
y=13/-b
y=-13/b
Check the picture below, notice, after 0 goes up then down back up at 4, and then it begins repeating after that, it begins to "periodically" be the same curve, that's the period.
C/d + 2 = f/g (subtract 2 from each side)
c/d + 2 - 2 = f/g - 2
c/d = f/g - 2 (multiply d to each side)
c/d*d = d(f/g - 2)
