Answer:

x ≤ -27

Step-by-step explanation:

$\frac{x}{-9}$ ≥ 3

to isolate the 'x' we need to multiply each side by -9

whenever you multiply or divide an inequality by a negative you must reverse the inequality symbol, therefore:

x ≤ -27

Using the equation of the circle, it is found that since it reaches an identity, the point (√5, 12) is on the circle.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

In this problem, the circle is centered at the origin, hence $(x_0, y_0) = (0,0)$ .

The circle contains the point (-13,0), hence the radius is found as follows:

$x^2 + y^2 = r^2$

$(-13)^2 + 0^2 = t^2$

$r^2 = 169$

Hence the equation is:

$x^2 + y^2 = 169$

Then, we test if point (√5, 12) is on the circle:

$x^2 + y^2 = 169$

$(\sqrt{5})^2 + 12^2 = 169$

25 + 144 = 169

Which is an identity, hence point (√5, 12) is on the circle.

I think it’s 8/55=4/x
So it’s 8x=4(55)
8x=220
x=220/8
x=27.5

What is the range and domain of the relation?<br><br> {(-3, 4), (-2, 0), (0, -1), (1, 2), (-3, 2)}?

Rus_ich [418]

Answer:

Range: {-1, 0, 2, 4}

Domain: {-3, -2, 0, 1}

Step-by-step explanation:

The range is the set containing all y-coordinates.

The domain is the set containing all x-coordinates.

A coordinate appears only once in each set.

Range: {-1, 0, 2, 4}

Domain: {-3, -2, 0, 1}
