Answer:
36w+5
Step-by-step explanation:
First you have to distribute the negative 9 within the parentheses. -4+9+36w. Then combine like terms. Therefore resulting in 36w+5.
2x + y = 1 . . . . . (1)
4x + 2y = -2 . . . .(2)
From (1), y = 1 - 2x . . . . . (3)
Putting (3) into (2) gives:
4x + 2(1 - 2x) = -2
4x + 2 - 4x = -2
2 = -2
Therefore, there is no x value as there is no solution for the set of equation.
Answer:
4th choice: I and IV only
Step-by-step explanation:
Change the form of the given equation to standard form.
y = -2/3 x + 2
3y = -2x + 6
2x + 3y = 6
Now compare this equation with the 4 choices.
Any equation that has the same x- and y-terms but a different constant term is parallel.
I. is parallel.
II. and III. are not parallel.
Look at IV.:
4x + 6y = 3
Divide both sides by 2:
2x + 3y = 3/2
IV. is also parallel.
Answer: 4th choice: I and IV only
