Answer:
B) Vertex: (–9,2); minimum
Step-by-step explanation:
Answer:
A - PV/RT = n
Step-by-step explanation:
The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.
Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.
PV = nRT
Divide both sides by R
PV/R =nT
Divide both sides by T
PV/RT = n
And now, the variable n has been isolated and the new equation to solve for moles is presented.
Hope this helps!
Answer:
its A & B, x<50
Step-by-step explanation:
atmost means till 50.
atleast means more than 50.
4x+1=13
4x=12
X=3
2x+y=8x-2y
2(3)+y=8(3)-2y
6+y=24-2y
3y=18
Y=6
