Which ordered pair is a solution to the following system of inequalities?

PtichkaEL [24]

Answer: (0,-1)

Step-by-step explanation:

Let's start with the first inequality, $y < -x^{2}+x$ . To check which points satisfy this inequality, we can substitute the x- and y-coordinates and see if they satisfy the inequality.

A) $-1 < -0^{2}+0 \longrightarrow -1 < 0 \longrightarrow \text{ True}$
B) $1 < -1^{2}+1 \longrightarrow 1 < 0 \longrightarrow \text{ False}$
C) $-3 < -2^{2}+2 \longrightarrow -3 < -2 \longrightarrow \text{ True}$
D) $-6 < -3^{2}+3 \longrightarrow -6 < -6 \longrightarrow \text{ False}$

Once again, we can repeat this for the second inequality (but this time, we only need to check the points that satisfy the first inequality).

A) $-1 > 0^{2}-4 \longrightarrow -1 > -4 \longrightarrow \text{ True}$
C) $-3 > 2^{2}-4 \longrightarrow -3 > 0 \longrightarrow \text{ False}$

Therefore, the answer is <u>(A) (0, -1)</u>.

The first four terms of a sequence are shown below: 9, 5, 1, â’3 Which of the following functions best defines this sequence? f(

matrenka [14]

The function that best defines this arithmetic sequence is:

$f(n) = f(n - 1) - 4, f(1) = 9$

<h3>What is an arithmetic sequence?</h3>

In an <em>arithmetic sequence,</em> the <u>difference between consecutive terms is always the same</u>, called common difference d.

The recursive function that defines the sequence is:

$f(n) = f(n - 1) + d$

$f(1) = f_0$

In which $f_0$ is the first term.

In this problem, the sequence is: {9, 5, 1, -3}

Each term is the previous term subtracted by 4, hence $d = -4$ .

The first term is 9, hence $f_0 = 9$ .

Hence, the function is:

$f(n) = f(n - 1) - 4, f(1) = 9$
