Answer:
y=4x-3
Step-by-step explanation:
Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.
y=4x+?
Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get
1=4(1)+b
reduce
1=4+b
subtract 4 from both sides
-3=b
and now we can add b=-3 into the original answer, and we get y=4x-3!

Answer:
The price after the discount but before the tax is $21
Step-by-step explanation:
Here, we are told there is a price off of 40% on an item that costs $35.
What we want to calculate is the value of what the price would be before the tax
We proceed by finding 40% of $35
Mathematically, that would be;
40/100 * 35 = $14
The price of the item before the tax is thus;
35-14 = $21
Answer:
I think the answer is 2n-5
(-3n + 2)+(5n - 7)
-3n+5n=2n
2+(-7)=-5
