Answer:

Domain : [0, ∞) {x | x ≥ 0} (equal to 0 all real numbers greater than or equal to 0).

Step-by-step explanation:

The given function is f(x) = √9x = 3√x

For this function f(x) is defined only if x ≥ 0 because for x < 0 the function is not defined.

f(-x) = 3√(-x) which is not defined.

Therefore domain of this function is domain: [0, ∞) {x | x ≥ 0}

Answer:

The domain is all real numbers greater than or equal to zero

Step-by-step explanation:

∵ f(x) = √9x

∴ The domain is all values of x ≥ 0

    because if x = number less than zero it will be negative

    There is no value in the real number for √-ve values

∴ The domain is all real numbers ≥ 0

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angl
nirvana33 [79]

The equation that solve for x is as follows;

70 + 60 + x = 180

<h3 /><h3>How to find an angle?</h3>

The equation that can be used to find the measure of angle x can be found as follows:

60 + 70 + y = 180

Therefore,

130 + y = 180

subtract 130 from both sides

130 - 130 + y = 180 - 130

y = 50°

70 + 60 + x = 180

130 + x = 180

x = 180 - 130

x = 50°

x and y are  vertically opposite angles.

Hey:) can you please help me posted picture of question
juin [17]
Answer:
x² - 10x + 21

Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.

This can be done as follows:
(x - 3)(x - 7)
x(x) + x(-7) -3(x) -3(-7)
x² - 7x - 3x + 21
x² - 10x + 21

Hope this helps :)
