10x2 -y + x2 =

11x²- y

Step-by-step explanation:

Simplifying an algebraic expression means to reduce said expression by grouping terms.

You can only group like terms, in other words, terms whose variables and exponents are the same ( y² and 5y² are like terms because they both have the variable y and the exponent 2. On the other hand y² and 3y³ are not like terms because they have different exponents and therefore you cannot group them).

You have the equation 10x² - y + x².

The like terms in this expression are 10x² and x², to group them we need to sum them up:

10x² + x² = 11x²

The other term is -y but there aren't any other like terms for it so it will remain the same.

Therefore, the expression 10x² - y + x² = 11x² - y

this answer is !

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
