All coordinates on the coordinate plane take the form (a, b), where a is the x value and b is the y value.

In order for a resulting graph to be a function, the graph must pass the vertical line test, which means that there cannot be more than one y value for one x value.

Thus, there cannot be any additional y values on the following values of x:

-3, -2, 1, and 2

Don't know where these numbers came from? I looked at the graph and listed every taken x value.

If any of the choices has any of the listed numbers as an x value, then it can be eliminated since it cannot be the answer.

After going through the process of elimination, we are left with the first choice, (-1, 2). This is your answer.

Have an awesome day!

The ordered pairs already plotted have x-coordinates: -3, -2, 1, and 2.

A function cannot have two ordered pairs with the same x-coordinate.

The answer cannot have -3, -2, 1, or 2 as the x-coordinate.

Answer: First choice (-1, 2)

Tamika has a hard rubber ball whose circumference measures 13 inches. she wants to box it for a gift but can only find cube-shap

Ostrovityanka [42]

The rubber ball, in this case, can be considered a circle with a circumference of 13 inches. So, we can find the diameter of the rubber ball using the formula $C=\pi d$ or $d=\frac{C}{\pi }$ . That is
$d=\frac{C}{\pi }=\frac{13\:inches}{\pi }=\frac{13}{\pi }=4.14\:inches$

Therefore, the diameter is greater than 4 inches and less than 5 inches. That means the smallest box that the ball will fit into with the top on is the 5 inches box.

What is the next term of the geometric sequence? 4/9, -4/3, 4

andreev551 [17]

Answer:

-12

Step-by-step explanation:

To find the ration, take the second term and divide by the first term

-4/3 ÷ 4/9

Copy dot flip

-4/3 * 9/4

-3

Multiply each term by -3

4*-3 =-12

A certain 5-digit combination lock can be reset with a new combination. The lock uses numbers from 1 to 6. After a friend accide

daser333 [38]

The probability is (1/6)^5 power. Since the locks are independent of each other, you can multiply the probabilities together. There are 6 possible numbers for each lock and there are 5 locks. So the probability is (1/6)^5 power.<span />

Work out the nth of this sequence:

Gekata [30.6K]

Answer:

$a_n = -11 +3(n -1)$

Explanation:

The $n$ th term of an arithmetic sequence is explicitly defined as $a_n = a_1 +d(n -1)$ where $a_1$ is the first term of the sequence and $d$ is the the common difference.
