An airport kept track of the number of flights that left on time for two different airlines data are shown in the relative frequency table what does the 0.3 in the yellow so mean

a. 30% of all the flights were on airline b and on time
b. 30% of all the flights were on time
c. 30% of airline b's flights were on time
d. 30% of all the flights were on airline b

i think the answer is:B (if the answer is wrong im so sorry)

(- 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 )

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
