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

Mathematics
1 answer:
PtichkaEL [24]2 years ago
3 0

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>.

Rewrite the expression using only positive integer exponents.
Andrews [41]

Answer:

So we got:

\left(m^{\frac{2}{3}}n^{\frac{-1}{3}}\right)^6

m^4\left(n^{\frac{-1}{3}}\right)^6\\

More attention for (n^{\frac{-1}{3}}\right))^6\\

n^{-2}

\frac{1}{n^2}

Join:

m^4\frac{1}{n^2}

\frac{1\cdot \:m^4}{n^2}\\\frac{m^4}{n^2}

Therefore, the answer is \frac{m^4}{n^2} , letter A
