The 130 juniors at Smithers High School are taking a class trip. Three buses will be taking the
students and chaperones to their destination, and
each bus can hold up to 45 people. The first bus
will be filled to capacity, followed by the second
and third buses. The function f(x) describes the
total number of people on the first bus, where x is
the number of minutes spent loading the bus. If
the first bus is boarded at a rate of 15 people per
minute, what is the domain of the function?

step-by-step explanation:

your mom

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
