Just add to find X
20 + 60 = 80
-------------------------------------
X = 80
To make sure plug it in
80 - 60 = 20
The equation is true
-----------------------------------------------
x = 80 is your answer
Answer:
-2x + 5
Step-by-step explanation:
When you set this problem up:
It's easy to see that you can't really divide them due to their differing variables. So, we need to factor the numerator to give us equivalent variables:
WAIT! Look at the longer factor:
It is equivalent to our denominator! Now, that has made the job incredibly easier. Simply cancel out the like terms in the problem and we have our answer:
(-2x + 5)
A) Minimum at (5,3) because the 4 (a) and the b (in front of the x is 1) are positive, the relation will be positive. When looking at the h (-5) you must always consider it as if it was the opposite sign. So here it's negative so in reality it's positive.
Answer:

Answer:
76.50
Step-by-step explanation:
We are given the fact that you bought an object for 90 dollars, and in which you sold said object for a loss of 15%, we are then asked how much would that object be sold for.
To find the answer, we need to subtract the original amount by the percent loss, so :
90 - 15%
15% of 90 is 13.5, therefore :
90 - 13.5
76.5
