WILL MARK BRAINLIEST IF THAT MATTERS Let’s take our function from before: f(x) = x + 2. Plug in some values for x. f(2) = 4. f(3) = 5. f(4) = 6.

Now we have a set of inputs and outputs for this function. You can write them as a set of ordered pairs, like this: (2, 4), (3, 5), (4, 6).

Like all sets of ordered pairs, these points can be plotted on a graph. If you plot

f(x) = x + 2 and connect the points, you will see that the graph is a straight line. This means that f(x) = x + 2 is a linear function.

Which of these is a set of inputs and outputs for the function f(x) = 2x + 4?

A

(1, 2), (2, 5), (3, 8)

B

(1, 4), (2, 6), (3, 7)

C

(1, 5), (1, 8), (1, 10)

D

(1, 6), (2, 8), (3, 10)

Will used 20 colored tiles to make a design in art class. 5/20 of his tiles were red. what is an equivalent fraction for the red tiles?

In a singing competition, there are 150 participants. at the end of each round, 40% of the participants are eliminated. how many participants are left after n rounds?

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
