There are 18,076 books in our public library. how should this number be written in expanded form? a) 10,000 + 8,000 + 70 + 6 b) 10,000 + 8000 + 700 + 6 c) 18,000 + 700 + 60+ 0 d) 18,000 + 70 + 60 + 0

  A) 10,000 + 8,000 + 70 + 6

Step-by-step explanation:

Write one digit at a time, with the others shown as zero. The sum of those numbers is the expanded form.

___

There are other ways to write a number in expanded form. One I like uses exponents to show the place value.

  1×10⁴ +8×10³ +0×10² +7×10¹ +6×10⁰

Understanding this form can help you write the number in scientific notation.

step-by-step explanation:

dd

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.
