a__ is a rule that assigns each value of the independent variable to
exactly one value of the dependent variable.

function

Step-by-step explanation:

function

Step-by-step explanation:

Functions are relationships or rules that assign each value of the independent variable (Domain) exactly one value of the dependent variable (Range)

For example if we have the following function:

The independent variable is x.

Notice that when:

In this way the function assigns an output value to each input value.

Therefore the answer is:

A_function_ is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

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.
