Answer:

domain: (-∞, ∞)

range:  (-∞, ∞)

Step-by-step explanation:

Domain is all your possible x-value that your graph includes. The only possible break in your function is that jump at x=1. Even though there's a jump at x=1, the bottom line has a solid circle, so that x=1 value is included in your function. There no break in the graph anywhere else so all other values are included in the domain, hence (-∞, ∞).

Range is all your possible y-value. Again, there's an open circle at y=2, but that circle is filled in with y=2 from the line on the right side, so y=2 is included in your function. There's no other point on the graph where the function break in the y-direction, therefore the range is (-∞, ∞).

Answer:

2x\sqrt{10}-2x\sqrt 5

Step-by-step explanation:

\sqrt{5x} (\sqrt{8x^2}-2\sqrt{x})\\\mathrm{Multiply \: parentheses \: by \sqrt{5x}}\\=\sqrt{5x \times 8x^2}-2\sqrt{5x \times x}\\=x\sqrt {4\times 10 x}-2x\sqrt{5}\\=2x\sqrt{10}-2x\sqrt{5}

A total of 750 tickets were sold for the school play. They were either adult tickets or student tickets. There were 50 more stud
Vlada [557]

Answer:

350 adult tickets were sold.

Step-by-step explanation:

Let's set up some values:

x = adult tickets

x + 50 = student tickets, since there were 50 more student tickets than adult tickets.

Now, let's set up our equation. If these two values add up to 750 tickets, then we can conclude the following:

(x) + (x + 50) = 750

2x + 50 = 750

2x = 700

x = 350 adult tickets. This means there were 400 student tickets sold.

trapecia [35]

Answer:

43

Step-by-step explanation:

So if there are 5 bags which each have 8 apples in them and we need to find out how many apples there are all we have to do is multiply 8 x 5 = 40

But there are 3 more apples off to the side so we just take 40 and add 3 to it.

40 + 3 = 43
