Answer:heyya
Step-by-step explanation:
<h3>
coefficient means the number before the variables...the coefficient of y is 5..i dont know whether that is X or multiplication sign..if it is the variable X raise to the power 2 then the coefficient of X raise to the power 2 is 4..</h3><h3>hope it helps</h3>
Answer:
There are two possibilities:
and 
and 
Step-by-step explanation:
Mathematically speaking, the statement is equivalent to this 2-variable non-linear system:


First,
is cleared in the first equation:

Now, the variable is substituted in the second one:

And some algebra is done in order to simplify the expression:


Roots are found by means of the General Equation for Second-Order Polynomials:
and 
There are two different values for
:






There are two possibilities:
and 
and 
Answer:
18.75%
Step-by-step explanation:
720 - (209+376) =
720 - 585 = 135
135/720 = 0.1875 --> 18.75%
Again, decimals and fractions represent all the values in between integers. Decimals are simply one step more of simplification from fractions.
