If -1 is a root of f(x), which of the following must be true A. a factor of f(x) is (x-1)
B. a factor of f(x) is (x+1)
C. both (x-1) and (x+1) are factors of f(x)
D. neither (x-1) nor (x+1) is a factor of f(x)

B

Step-by-step explanation:

It is not certain which type of function f(x) is but what we do know is that if something is a root, then it is where the function will cross the x axis or where f(x) = 0.

If -1 is a root of f(x), f(-1) = 0.

If a factor of f(x) is (x+1), f(-1) = (-1 + 1) = 0.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
