Answer:
The point
is not a solution of the system of inequalities
Step-by-step explanation:
we have
-----> inequality A
-----> inequality B
we know that
If a ordered pair is a solution of the system of inequalities
then
the ordered pair must be satisfy the inequalities of the system
Verify
For 
substitute the value of x and the value of y in the inequalkity A and in the inequality B
Inequality A

-------> is not true
therefore
The point
is not a solution of the system of inequalities
F(x)=2x+3. easy as that, just replace y with f(x)
B is the correct answer because 1 gallon of gas is 1.05 dollars, so 15 × 1.05 is 15.75...
Answer:
The slope is 0
Step-by-step explanation:
The slope is the change of y over the change in x. Since y doesn't change at all, it's 0 over 3. 0/3 is just 0, so the slope is 0.
5/x² = 5x⁻²
