Answer: The answer is true.
Step-by-step explanation: The given statement is
'If a system of two inequalities has a solution, then their two half planes intersect'.
We are to check whether the statement is true or false.
Let a system of two inequalities be
These inequalities has a solution, for example, x = 2, y = 1.
Plotting these inequalities on a graph paper (please see the attached graph), we see that the two half planes intersect, which is represented by the double shaded region in the graph.
Thus, the given statement is TRUE.
Answer:
$3.63
Step-by-step explanation:
A 10-minute call to France cost $3.19.
A 15-minute call to France costs $4.29.
Now we will use two point slope form
Substitute the values :
y is the cost and x is the number of minutes
Now we are suppose to find cost of a 12-minute call to France
Substitute x = 12
Hence the cost of a 12-minute call to France is $3.63
