The graph of y2+3x=0 is symmetric with respect to which axis?
natta225 [31]

Answer:

The graph of y2+3x=0 is symmetric with respect to the x-axis

Step-by-step explanation:

To establish symmetry with respect to the x-axis we simply substitute -y in place of y in the original equation. If the resulting equation is identical to the original one then the function is said to be symmetric with respect to the x-axis.

In this case we have;

y^{2} +3x=0\\(-y)^{2} +3x=0\\y^{2} +3x=0

Which is identical to the original equation

Anvisha [2.4K]

Answer:

P(black) = 2/3

Step-by-step explanation:

We need to find the total number of marbles

2 red marbles+ 3 white marbles+ 10 black marbles = 15 marbles


To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles

P(black) = black marbles/total marbles

            = 10/15

Divide the top and bottom by 5

            = 2/3
