Answer:
y = -3x+4
Step-by-step explanation:
y = -3x+b
7=-3(-1)+b
7=3+b
4=b
Answer:
y⁷/x⁵ , I hope this helps
|-3|=3 right?
Then it is
3*-6=-18
Ok, to solve this first you have to set up your proportion:
9/150=x/230
/ is a fraction
x= the number of vials it will take to treat 230 patients
in order to solve this, you have to cross multiply:
9 x 230= 2070
150 · x= 150x
so you get 150x=2070
then divide 2070 by 150
2070/150= 13.8
so it would take 13.8 vials of medicine to treat 230 patients
