-10 is the value of the given polynomial.
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.
First, we can simplify the polynomial by combining like terms:
[tex]2x^2y + 4x^2y + 3xy^2 - 5xy^2 - 3xy + y^2\\= (2x^2y + 4x^2y) + (3xy^2 - 5xy^2) + (-3xy + y^2)\\= 6x^2y - 2xy^2 - 3xy + y^2[/tex]
Now, to evaluate for x = 1 and y = -2, we substitute those values into the simplified expression:
[tex]6(1)^2(-2) - 2(1)(-2)^2 - 3(1)(-2) + (-2)^2\\= 6(-2) - 2(4) + 6 + 4\\= -12 - 8 + 6 + 4\\= -10[/tex]
Therefore, the value of the polynomial for x = 1 and y = -2 is -10.

If this library has 134,000 books, find how many books are in the category of reference or other?
Answer:
134,000-X=Y
Step-by-step explanation:
you'll first have to solve how many categories there are, but since we don't know we'll use X, we already know that there is 134,000 books, but we don't know how many books are reference or other, so we use Y to represent that.
so it's
134,000-X=Y

Xander and Carly have a total of $12,000 to invest. If Zander tripled his money and Carly doubled her money, then they would have $31,000 to invest. How much money do each of them currently have? SOLVE this in TWO ways. Visually without variables and using algebra.
Answer:
Zander starts with 7,000; Carly starts with 5,000
Step-by-step explanation:
1 - Visually solving
Looking at the final value (31,000) one could interpret the sums of the numbers tripled and doubled respectively would need to equate to 31,000.
Taking off the additional zeros could also prove beneficial. To get 31, one of the numbers tripled or doubled would need to either be 11 or 21. 11 is a prime number, so that can be cancelled out. 7 multiplied by 3 (triple) produces 21.
12 - 7 = 5. Solving for the leftover 5 which would be doubled, you would get 10.
10 + 21 = 31.
2 - Algebra
x - Zander; y - Carly
To begin with you should need the initial formula.
x + y = 12,000
Your second formula would then take into consideration the changes made to x and y
3x + 2y = 31,000.
Using process of elimination or substitution, (either method works), you will find x = 7,000 and y = 5,000

Calculate the distance between the points J = (- 2, - 1) and A = (3, - 7) in the coordinate plane Round your answer to the nearest hundredth
Answer:
The distance between the points is 7.81 (to the nearest hundreth)
Step-by-step explanation:
The distance formula between two points in the coordinate plane is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Put,
[tex]J(x_1,y_1)=(-2,-1)\\A(x_2,y_2)=(3,-7)[/tex]
Hence,
[tex]d=\sqrt{(3-(-2))^2+(-7-(-1))^2} \\d=\sqrt{(3+2)^2+(-7+1)^2} \\d=\sqrt{5^2+(-6)^2} \\d=\sqrt{25+36} \\d=\sqrt{61} \\d=7.810[/tex]
