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;

Which is identical to the original equation
Answer:
If the radius of a circle is 5 inches, the diameter is 10.
Step-by-step explanation:
This is because to find the diameter of a circle sing the radius is to multiply it by two. 5x2=10
So the diameter is 10. If you want to find the radius just reciprocate the process, divide the diameter by 2 and yo will get the radius.
I really hope this helped you out. Make sure to give my answer brainliest. Have a radiant day or night ! :D
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
