Answer: -1410

Step-by-step explanation:

Let's start by subbing in -4 for x

$-4x^4 - 3x^3 - 29x^2 - 114\\-4(-4)^4-3(-4)^3-29(-4)^2-114$

Now we can solve

$-4(256)-3(-64)-29(16)-114\\-1024--192-464-114\\-832-464-114\\-1296-114\\-1410$

Use elimination to find the solution to the system of equations. -x+2y=9 4x+5y=3

lukranit [14]

Let's eliminate x. Mult the first eq'n by 4, obtaining

-4x + 8y = 36

Now add the 2nd equation to this result:

-4x + 8y = 36
4x + 5y = 3
--------------------
13y = 39, so y = 3.

Subst. 3 for y in the 2nd equation and solve the result for x:

4x + 5(3) = 3 => 4x = -12 => x = -3. Solution is (-3,3).
