Answer:
I would eliminate both of the -4x because they are identical.
Step-by-step explanation:
Cancel out the both of the -4x by eliminating them. Then subtract the 3y - y. Subtract the -19 - 15. You then will be left with 2y = -34. Solve for y. Then plug y back into the equation to solve for the x.

Answer:
The expression is (---- + 2x)³
Step-by-step explanation:
To represents a verbal expression as an algebraic expression, we must use mathematics symbol and variables (name the unknowns quantity by letters)
The verbal expression is:
<em>Cube of more than two times a number</em>
→ Give a name for the number, assume that it is x
→ More than means (+)
→ Two times means multiply the number by 2 (x × 2)
→ The cube means power 3 for (---- more than 2x)
∴ The expression is (---- + 2x)³
<em>If the missing is 5, the statement will be The cube of 5 more than two times a number.</em>
∴ The expression is (5 + 2x)³
→ You can choose any number of the missing part
Given:
The three points are (1,2), (2,3) and (-2,-11).
To find:
Whether the given points are collinear.
Solution:
Let as consider the three points are A(1,2), B(2,3) and C(-2,-11).
If these three points are collinear, then area of 
must be 0.
Area of ,
Therefore, the given points are not collinear.
Answer:
G
Step-by-step explanation:
Red marble probably currently: 12/32 = 3/8
Guess and check (using the multiple choice answers):
F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5
G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5
H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5
J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5
K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5
Answer:
The answer is D. Hope this helps
