Someone please help me with this!! <3

Um, your sum should be 4.

Step-by-step explanation: The sum of an infinite geometric series can be found using the formula where a is the first term and r is the ratio between the successive terms.

For , find the first term in the series by substituting in the lower bound and simplifying: a=1.

For r, find the ratio of successive terms by plugging into the formula and simplifying: .

For 1–r, substitute the values of the ratio and first term into the sum formula: ; ∴, your sum should be 4.

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.

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
