The graph of which function has an axis of symmetry at x = 3?

Mathematics
1 answer:
USPshnik [31]3 years ago

You do this by converting to vertex form a(x - b)^2 + c   where the axis of symmetry  is x = b

the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one 

x^2 - 6x - 1 =  (x - 3)^2 -9-1

the last option is the correct one

The area of a square piece of tissue paper is 25 square centimeters. How long is each side?
andrey2020 [161]
5 centimeters. The area is Width times Height, and with a square the width and height are the same so just do "x²=25" and x would be 5.

12. The $60 selling price of a camera is the cost<br> increased by twice the cost. Find the cost.
prisoha [69]

Answer: Assuming you mean that the original cost was doubled and now equals $60, the camera costed $30. Assuming the camera's price has been doubled from $60, it is $120. The wording is a bit unclear, so I'm giving you both answers.

Step-by-step explanation: To find half of the price of $60, simply divide it by 2, which gives you $30.
