According to the rational root theorem, the following are potential roots of f(x) = 60x2 – 57x – 18
-6/5, -1/4, 3, 6
which is an actual root of f(x)?

-6/5
-1/4
3
6

We have been given the function

Now, the given potential roots are -6/5, -1/4, 3, 6. In order to find the actual root of this function, we substitute the root in the given function and if we get zero, then that would be the actual zero.

We got zero for the value -1/4.

Hence, the actual root of f(x) is -1/4.

B is the correct option.

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
