What is the domain for each function below? Choose the correct inequality symbol from the drop down menu and fill in the blank w

erik [133]

Answer:

$x \le 3$

$x \ge 0$

Step-by-step explanation:

The functions, missing from the question are:

$f(x) = \sqrt{3 - x$

$f(x) = \sqrt{3 x$

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

$f(x) = \sqrt{3 - x$

Equate 3 - x to 0

$3 - x = 0$

Solve for x

$-x = -3$

$x = 3$

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

$x \le 3$

(b)

$f(x) = \sqrt{3x$

Equate 3x to 0

$3x = 0$

Solve for x

$x = 0$

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

$x \ge 0$

Elden [556K]

x = number of chicken wings

y = number of sliders

60x + 225y = 1380

Solve Each Equation PLS SHOW WORK<br><br> |8m + 7| - 5 = 60

diamong [38]

Answer:

m = 7.25

Step-by-step explanation:

8m + 7 - 5 = 60

Evaluate like terms.

8m + 2 = 60

Isolate 8m.

8m = 60 - 2

Evaluate.

8m = 58

Find m.

m = 58 ÷ 8

m = 7.25
