The temperature, t, in degrees Fahrenheit, can be found by counting the number of cricket chirps, c, heard in 14
seconds and then adding 40. The equation t = c + 40 models the relationship between the temperature and the
number of cricket chirps.
What is true about the graph that represents this real-world scenario? Select two options,
The graph is continuous
All values of t must be positive.
O A viable solution is (-2, 38).
A viable solution is (0.5, 40.5).
A viable solution is (10, 50).

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

b

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
