To find the midpoint of 2 points.. we have to add x coordinates and y coordinates and halve them.
in this case, mid point would be((-6 + 6) /2, (0+5)/2) = (0, 2.5)
Let me know if the solution is clear.
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.
Answer:
Yes, it is B
Step-by-step explanation:
Plug in 4 and 3 into the equations
2(4) - 3(3) = -1
8 - 9 = -1
-1 = -1
4 = 3 + 1
4 = 4
Answer:
Step-by-step explanation:
Read this is as "x is 5 units away from _____ on a number line?" We don't have a number that x is 5 units away from, so that number is just 0. The absolute value inequality is
| x - 0 | ≤ 5
If you were to take this expression out of the absolute value symbols and put it into an inequality statement, because it is a "less than or equal to" inequality, that makes this a conjunction, and
-5 ≤ x ≤ 5
because those numbers greater than -5 and less than 5 are all less than 5 units away from 0.
