f(x)=(anything greater than 1)x+2
Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
Answer:
2/3 cup of pineapple juice for 1/3 cup of orange juice to make 1 smoothie
Let the no. Of smoothies be x
x/3 = 111
x = 333 smoothies
Cups of pineapple juice = 222
Hope this helps!
The two inequalities can be rewritten as

The solution is composed by every point below the graph of the line
, and above the horizontal line 
To draw the line
we can build a little table (only 2 points are required):

So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.
To draw the line
, simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.
Choose the above/below areas as specified above to solve the system.
