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? check all that apply. the graph is continuous. all values of t must be positive. a viable solution is (–2, 38). a viable solution is (0.5, 40.5). a viable solution is (10, 50).

Option a and d.

Step-by-step explanation:

Given that 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.

c, the no of cricket chips cannot be negative or in decimal/fractions.

Although the graph is linear but cannot be continuous as c takes only integral values.

Hence the correct choice are:

i) All values of t must be positive

ii) A viable soluton is (10,50)

ddd

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
