The y coord becomes the negative x coord and the x coord becomes the y coord. So (-3,7) becomes (-7,-3).
Answer:
0.508 cm
Step-by-step explanation:
Your problem statement tells you that you can find the number of centimeters by multiplying 1/5 inch by 2.54 cm/in:
1/5 × 2.54 = 0.508
1/5 inch is 0.508 centimeters
Answer:
the equation of the axis of symmetry is 
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form:
, being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form:
, is given by:

which in our case becomes:

Then, the equation of the axis of symmetry for this parabola is:

Answer:
129.99
Step-by-step explanation:
129.99 rounds to 130 because the 9 in the hundredths place causes the 9 in the tenths place to round up, making the number 130.0.
