What binomial do you have to add to the polynomial 2x^2+3y^2-5xy+1 to get the following?
Contact [7]

Binomial -3y^{2}+5xy when added to polynomial 2x^{2} +3y^{2} -5xy+1  gives  polynomial  that does not contain the variable y .

<h3>What is binomial?</h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign .

Example: x + 2 is a binomial, where x and 2 are two separate terms.

<h3>What is polynomial?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer

According to the question

polynomial 2x^{2} +3y^{2} -5xy+1

when added with  -3y^{2}+5xy  

= 2x^{2}+1   (as 3y^{2} -5xy got cancelled )

that does not contain the variable y

Hence, Binomial -3y^{2}+5xy when added to polynomial 2x^{2} +3y^{2} -5xy+1  gives that does not contain the variable y .

Year 9 Maths - linear equations please help
jek_recluse [69]

Answer:

x=1 & y=6 or (1,6)

Step-by-step explanation:

3x-x+5=7   Substitute the 2nd equation in for y  

2x+5=7      Do 3x-x to get 2x

2x=2          Subtract 5 from both sides

x=1              Divide 2 from both sides

y=1+5          Insert 1 as x

y=6             Add 1+5 to solve for y

Hope this helped!
