Answer:
x=-16
Step-by-step explanation:
x+7=-9
x+7-7=-9-7
x=-16
2 tickets = $16
1 ticket = $16 ÷ 2 = $8
5 tickets = $40
1 ticket = $40 ÷ 5 = $8
Since both shows that each ticket costs $8, they are equivalent.
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.
