the ratio of boys to girls on the swim team is 2:3. If there are 40 swimmers on the team, how many of them are girls?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .

x=3y-6

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.
