Answer:
A. a parabola that opens down.
Step-by-step explanation:
First we can eliminate two answers, b and d, since parabalas that open left or right use the y variable.
Now the equation of a standard parabola is x². This means that there are no negative y values, and therefore it cannot open down, it is up.
With a NEGATIVE coefficient, the graph is flipped over the x axis, therefore making it open down.
Graphical proof is attached for further understanding, positive a is in red, negative a is in blue.
Answer:
Step-by-step explanation:
Let the Price of TV set be x.
The price of computer = x - 5200
x + x - 5200 = 105200
2x = 105200 + 5200
2x = 110400
x = 110400/2
x = Rs. 55200
Price of TV set = Rs. 55200
Price of computer set = 55200 - 5200 = Rs. 50000
18b-15
-3x-6b=18b
-3x5=-15
hope this helps, if it doesn't don't hesitate to tell me :)
