Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
Start off by making a ratio and write down the given. From there solve and multiply. Hopefully the picture helps :)

Option C. 
Step-by-step explanation:
we know that
In the rectangle of the figure

so

The constant is equal to 
Answer:
Even Function
Solution:
For an even function:
f(x) = f(-x)
For an odd function:
f(x) = -f(x)
Since f(-x) = f(x), the given function is an even function.
Answer:
(0,0) or Infinitely many solutions.
Step-by-step explanation:
-−4x−4y=0
−4x−4y+4y=0+4y(Add 4y to both sides)
−4x=4y
−4x/-4= 4y/-4
(Divide both sides by -4)
x=−y
4x+4y=0
4(−y)+4y=0
0=0
