Answer:

Step-by-step explanation:

You have to understand two things about this question.

f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2
The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.

f(-3) = 2(-3)^2

f(-3) = 2 * 9

f(-3) = 18

Remember that (-3) ^2 = -3 * - 3 = 9 a positive.

F(-3)=-12
because f(x) is y=2*2=4

X – 10y = 18<br> -6x – 10y = 32

viva [34]

Answer:

Step-by-step explanation:

$x - 10y = 18$

$-6x - 10y = 32$

Since both equations have $-10y$ , we can subtract the second equation from the first to try and solve for $x$ :

$(x - 10y) - (-6x - 10y) = 18 - 32$

$x - 10y + 6x + 10y = -14$

$7x = -14$

$x = -2$

With this, we can plug the value back into the first equation to solve for $y$ :

$(-2) - 10y = 18$

$-2 - 10y = 18$

$-10y = 20$

$y = -2$

Therefore, the solution is $x = -2, y = -2$

Classify each polynomial as a monomial, binomial, or trinomial. Combine like terms first.

brilliants [131]

Classify each polynomial as a monomial, binomial, or trinomial. Combine like terms first.

We can classify the polynomial according to the number of terms

If we have one term then it is monomial

If we have two terms then it is binomial

If we have three terms then it is trinomial

(1) $x^3 + 3x^3 + 2x$

$4x^3 + 2x$

We have two terms so it is Binomial

(2) $2x^3 + 5x + 3x^4 - x$

$2x^3 + 4x + 3x^4$

We have three terms so it is Trinomial

(3) $4x - 5x + x - 2$

$4x - 5x + x - 2$

-2

We have one term so it is monomial

(4) $6x^2 + 5 - 2x^2 - 9$

$4x^2 - 4$

We have two terms so it is Binomial
