8 0

Answer:

B. $2+\frac{1}{3}n=8$

Step-by-step explanation:

Let n be the number.

We are asked to write an mathematical expression for the given word phrase.

One third of a number, n, would be $\frac{1}{3}n$ .

Two more than one third of a number, n, would be $2+\frac{1}{3}n$ .

We are told that Two more than one-third of a number is 8. We can represent this information in an equation as:

$2+\frac{1}{3}n=8$

Therefore, option B is the correct choice.

Two more means something + 2
One third = 1/3
Of a number is some undefined number i.e. a variable
is 8 just means mean = 8

Can you figure this out?

Graph each absolute value function. State the domain, range, and y-intercept.

SVEN [57.7K]

Answer:

The domain is $(-\infty,\infty)$ and its range is $[3,\infty).$

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function $y=|x|.$ Its domain is $x\in (-\infty,\infty)$ and its range is $y\in [0,\infty).$

The graph of the function $y=|x|+3$ is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is $(-\infty,\infty)$ and its range is $[3,\infty).$
