Dolbear’s law relates the number of chirps per minute made by snowy tree crickets, n, and the air temperature, t, in degrees fahrenheit t=50{n-4}{4}

to predict the number of chirps at any temperature, rewrite the formula to solve for n.

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.

r and t.

both are 64 degrees.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
