Step-by-step explanation:
The x intercept of -5y=4-2x equals (2,0)
Correct answer is C there are no solutions since the X gets cancelled out and 7 does not equal 8, so the answer is C
Answer:approximately 65.6
Step-by-step explanation:
Use equation C1M1+C2M2=CM
C1=15%, M1=10000 mg (starting ointment)
C2=0% M2=to be found (diluent)
C=12% M=M1+M2 (product)
Solve for M2
0.15*10000+0*M2 = 0.12(10000+M2)
M2=(0.15-0.12)*10000/0.12=2500 mg
Answer: 2500 mg of diluent is required.
