what is the simplified expression of the following polynomial: xy4 + 5y7 - (6xy + 7y7) - x8y2 + (-3xy4) Step by Step

Gnoma [55]

Answer:

-x^8y^2 -2y^7 -2xy^4 -6xy

Step-by-step explanation:

Eliminate parentheses.

xy^4 + 5y^7 - 6xy - 7y^7 - x^8y^2 -3xy^4

Arrange in descending degree order, group like terms.

-x^8y^2 +(5y^7 -7y^7) +(xy^4 -3xy^4) -6xy

Combine like terms.

-x^8y^2 -2y^7 -2xy^4 -6xy

Which of the following points does not lie on the line whose equation is x+ y = 7?

makkiz [27]

The answer is (-1, -6)

Let's go through all choices:
1. (x, y) = (-10, 17)
x + y = 7
-10 + 17 = 7
17 - 10 = 7
7 = 7
So, these points lie on the line.

2. (x, y) = (13/3, 8/3)
x + y = 7
13/3 + 8/3 = 7
(13 + 8)/3 = 7
21/3 = 7
7 = 7
So, these points lie on the line, too.

3. (x, y) = (-1, -6)
x + y = 7
-1 + (-6) = 7
-1 - 6 = 7
-7 ≠ 7
So, these points DO NOT lie on the line.

The map shows the location of the airport and a warehouse in a city. Though not displayed on the map, there is also a factory 10

kipiarov [429]

step 1

find the coordinates of the factory

the factory is 104 miles due north of the warehouse

the coordinates of the warehouse are (39,-52)

coordinates of the factory------> (39,-52+104)------> (39,52)

step 2

find the distance warehouse to airport

let

A coordinates of warehouse-------> A( 39,-52)

B coordinates of airport---------> B(-39,52)

C coordinates of factory-------> C(39,52)

distance AB=√[(52+52)²+(-39-39)²]------> distance AB=130 miles

step 3

find the distance airport to factory

B(-39,52)

C(39,52)

distance BC=√[(52-52)²+(39+39)²]-----> distance BC=39 miles

the total number of miles=distance AB+distance BC---> 130+39

the total number of miles=169 miles

Thus the answer is 169
