Tony rounded each of the numbers 1,183 and 1, 145 to the nearest hundred. Which choice correctly compares the rounded

nydimaria [60]

Answer:

1,200 > 1,100

Step-by-step explanation:

This is because 1,183 is rounded up to the nearest hundred which is 1200 (since 8 which is the tens digit is greater than 5) and 1,145 is rounded down to the nearest hundred which is 1,100 (since 4 which is the tens digit is less than 5).

So, 1,200 > 1,100

-4x^4 - 3x^3 - 29x^2 - 114 where x= -4

tatiyna

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

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