I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct

Since both 3x and 6x have the variable x in it, we can just go ahead and add 3 and 6.
3x+6x=9x
<u>Answer:</u>
3/5
<u>Step-by-step explanation:</u>
We are to find the similarity ratio of a cube with volume 
to a cube with volume 
.
We know the formula for the ratio of two cubes:
where 
is the similarity ratio of the two cubes.
Substituting the given values in the formula to find :
Therefore, the similarity ratio of the two cubes is 3/5.
Answer:
The flip flops cost $25.56 after the discount and tax.
Step-by-step explanation:
A pair of flip flops is $30. This is our starting amount.
The tax will be applied on the price the flip flops are bought for. This means we must apply the discount first.
The discount is 20%. Let's find what the flip flops were sold for.
If the discount is 20%, the flip flops were sold for 80% of their original price. Let's find 80% of 30.
80% of 30 = ?
0.80 • 30 = ?
= 24
The flip flops were sold for $24.
Now we have to apply a 6.5% tax. To find the amount of money added to the total, we need to find 6.5% of 24.
6.5% of 24 = ?
0.065 • 24 = ?
= 1.56
The tax was $1.56.
We need to add the tax to the discounted price.
1.56 + 24 = ?
= 25.56
The flip flops cost $25.56 after the discount and tax.
Hope this helps!
