elena55 [62]

Answer:

DOMAIN: (-\infty,1]\cup(2,\infty)

RANGE: (-\infty,\infty)

Step-by-step explanation:

The domain of a graph is the span of x-values covered by the graph, while the range of a graph is the span of y-values covered by the graph.

DOMAIN:

From the graph, we can see that the x-values covers everything to the left of x=1. Then we stop and then continue beginning at x=2 all the way until positive infinity.

However, note that at x=1, the dot is a closed circle while at x=2, the dot is an open circle. Thus, we will include x=1 into our domain but not include x=2 into our domain.

So, our domain is all values greater than or less than 1, and all values greater than 2.

In interval notation, this is:

(-\infty,1]\cup(2,\infty)

We use brackets with the 1 because we include it in our domain and we use parentheses with the 2 since we do not.

RANGE:

Looking at the graph, it seems that all y-values are covered. The part of the graph on the left covers all y-values less than or equal to 3, while the part of the graph on the right covers all y-values greater than -1. Thus, all y-values are covered.

Our range is all real numbers.

In interval notation, this is:

(-\infty,\infty)

Help me PLEASEEEEEEEEEEEEE
qwelly [4]

Answer:

D. 144

Step-by-step explanation:

find the volume of the shipping container and divide it by the volume of a box.

2\frac{2}{3} × 1 × 2 = \frac{16}{3}

\frac{1}{3} × \frac{1}{3} × \frac{1}{3} = \frac{1}{27}

\frac{16}{3} divided by \frac{1}{27} is 144.

Solve for y, 12x-20y=180​
nydimaria [60]

Answer:

y=35x−9

Step-by-step explanation:

Step 1: Add -12x to both sides.

12x−20y+−12x=180+−12x

−20y=−12x+180

Step 2: Divide both sides by -20.

−20y−20=−12x+180−20

y=35x−9
