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>.

A kayaker traveled 4 5/6 miles during the first hour, and 1 1/3 miles more then the next hour. How far did he travel in 2 hours
ss7ja [257]

Answer:

11 miles

Step-by-step explanation:

Given that :

Distance traveled in first hour = 4 5/6 miles

Distance traveled in the next hour = 4 5/6 + 1 1/3

Therefore, the total distance traveled in 2 hours equals :

4 5/6 miles + (4 5/6 miles + 1 1/3 miles)

29/6 + 29/6 + 4/3

L. C. M of denominator = 6

(29 + 29 + 8) / 6

= 66 / 6 miles

= 11 miles

Distance traveled in 2 hours =. 11 miles
