Answer:

\frac{7y^{2} +9x}{4} and 6y²+5x

Step-by-step explanation:

Polynomials are algebraic expressions involving one, or even more than one variables raised to any power summing each other. Generally speaking, in other words an one variable Polynomial is

a_{0}+a_{1} x+a_{2} x^{2}...a_{n} x^{n}

So a multivariate polynomial expression are \frac{7y^{2} +9x}{4} and 6y²+ 5x.

Because in the other options:

We have a Radical of an Irrational number\sqrt{3} =3^{\frac{1}{3}} times x (2nd option) what does not configure a polynomial.

And a Polynomial Quotient with a variable on the denominator, described by:

P(x)=\frac{Q(x)}{R(x)} \\ P(x)=q(x)*Q(x)+R(x)

Like the last option:

\frac{7x^{2}+8}{4x}

19) Solve the system,<br> *****<br> x + 3y - 5<br> -2x + 2y = 14
faust18 [17]

Answer:

y = 3

x = -4

Step-by-step explanation:

Hopefully the first equation is x + 3y = 5

x = 5 - 3y

Plug in:

-2(5 - 3y) + 2y = 14

-10 + 6y + 2y = 14

8y = 24

y = 3

x = -4

Tickets for a concert cost eight dollars for the main floor and six dollars for the balcony If 1125 tickets were sold and the ti
cricket20 [7]

Answer:

650 tickets for the main floor and 475 tickets for the balcony were sold.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=1125 (1)

8x+6y=8050 (2), where:

x is the number of tickets for the main floor

y is the number of tickets for the balcony

First, you can solve for x in (1):

x=1125-y (3)

Second, you can replace (3) in (2):

8(1125-y)+6y=8050

9000-8y+6y=8050

9000-2y=8050

9000-8050=2y

950=2y

y=950/2

y=475

Third, you can replace the value of y in (3) to find x:

x=1125-y

x=1125-475

x=650

According to this, the answer is that 650 tickets for the main floor and 475 tickets for the balcony were sold.
