Add the following polynomials then place the answer in the proper location 2x^3+4x-6 3x^3-8x+7

5x^3 - 4x + 1

Step-by-step explanation:

To add the polynomials, combine like terms which ha the same variable and exponent.

2x^3 + 3x^3 = 5x^3

4x - 8x = -4x

-6 + 7 = 1

So it adds to 5x^3 - 4x + 1

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
