Answer:

Yes, because it passes the vertical line test. If we were to draw a vertical line anywhere on the graph, it would only go through one point, so the relation is a function.

Step-by-step explanation:

1. This graph is a function because it passes the vertical line test. The vertical line test is a simple method that is used to determine if a relation is a function or not. A function can one output (y) for every unique input (x). If we were to draw a vertical line anywhere on the graph, and it would only go through one point, then the relation is a function. If it went through multiple points in some areas, it's not a function.

2. Since we can draw a vertical line anywhere and have it pass through one point, this relation is a function.

Answer:

C. (–4, 0), (–2, 0), (1, 0), and (3, 0).

Step-by-step explanation:

The points where the graph intersects the x axis have y coordinates of zero and the given x coordinates.

(–4, 0), (–2, 0), (1, 0), and (3, 0) is the answer.

What coordinates for point c would make pqt simular to abc

Dafna1 [17]

Answer:

A. (7, -5)

Step-by-step explanation:

The given coordinates of the vertices of ΔPQT are;

P(-2, 5), Q(-2, 1) and T(-5, 1)

The length of the side TQ = 3 units

The length of the side PQ = 4 units

Therefore, the length of the side PT = √(3² + 4²) = 5

The coordinates of the line segment AB = A(1, 3), B(1, -5)

Therefore, using a scale factor of 2, where the sides PQ and AB are corresponding sides, we have;

Where BC is the corresponding side to the TQ on ΔPQT, we have;

The length of BC = 2 × The length of TQ = 2 × 3 units = 6 units (distant from <em>B</em> along the x-axis)

Therefore, the possible points for the point <em>C</em> are;

C(1 - 6, -5) or C(1 + 6, -5)

C(-5, -5) or C(7, -5)

Therefore, the correct option is option A. C(7, -5).

Enter the equation of the circle with the given center and radius. Center: (−2, −5); radius= 1

statuscvo [17]

Answer:

$(x + 2)^2 + (y + 5)^2 = 1$

Step-by-step explanation:

Equation of a circle:

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

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

Center: (−2, −5); radius= 1

This means that $x_0 = -2, y_0 = -5, r = 1$ . So

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

$(x - (-2))^2 + (y - (-5))^2 = 1^2$

$(x + 2)^2 + (y + 5)^2 = 1$

This is the equation of the circle.
