The associative property states that you can add or multiply regardless
of how the numbers are grouped. By 'grouped' we mean 'how you use
parenthesis'. In other words, if you are adding or multiplying it does
not matter where you put the parenthesis. Add some parenthesis any where
you like!.
The given line (in blue) is a vertical line, so it is in the form
Ax=C (i.e. with the y-term missing).
Since we know that the line passes through (-2,2), and (-2,-3), this means that all points on the line has the x-coordinate equal to -2 (characteristic of vertical lines).
The equation is therefore
x=-2, or alternatively
x+2=0
Answer: 60%

Answer:
alright, let's talk
Step-by-step explanation:
how are you doing?
hope you are good?
have a great day!!
When a quantity grows (gets bigger), then we can compute its PERCENT INCREASE:
[beautiful math coming... please be patient] <span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span></span>
Some people write this formula with <span><span>100%</span><span>100%</span></span>
at the end,
to emphasize that since it is percent increase, it should be reported as a percent.
So, here's an alternate way to give the formula:
<span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span></span>
Recall that <span><span>100%=100⋅<span>1100</span>=1</span><span>100%=100⋅<span>1100</span>=1</span></span>
.
So, <span><span>100%</span><span>100%</span></span>
is just the number <span>11</span>
!
Multiplying by <span>11</span>
doesn't change anything except the name of the number!
Hope this helps
