Example Questions

Example Question #301 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(34,-28\right)\) included in the inequality\(\displaystyle y\geq- 26 x^{3}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -28\geq-26\cdot34^{3}\)\(\displaystyle -28\geq-26\cdot39304\)\(\displaystyle -28\geq-1021904\)

Since \(\displaystyle -28\)is greater than\(\displaystyle -1021904\)the point is included in the inequality.

Example Question #302 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(47,-18\right)\) included in the inequality\(\displaystyle y\geq- 7 x^{5}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -18\geq-7\cdot47^{5}\)\(\displaystyle -18\geq-7\cdot229345007\)\(\displaystyle -18\geq-1605415049\)

Since \(\displaystyle -18\)is greater than\(\displaystyle -1605415049\)the point is included in the inequality.

Example Question #303 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(35,-32\right)\) included in the inequality\(\displaystyle y\geq- 32 x^{2}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -32\geq-32\cdot35^{2}\)\(\displaystyle -32\geq-32\cdot1225\)\(\displaystyle -32\geq-39200\)

Since \(\displaystyle -32\)is greater than\(\displaystyle -39200\)the point is included in the inequality.

Example Question #304 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(32,-39\right)\) included in the inequality\(\displaystyle y\geq- 25 x^{4}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -39\geq-25\cdot32^{4}\)\(\displaystyle -39\geq-25\cdot1048576\)\(\displaystyle -39\geq-26214400\)

Since \(\displaystyle -39\)is greater than\(\displaystyle -26214400\)the point is included in the inequality.

Example Question #305 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(13,3\right)\) included in the inequality\(\displaystyle y\geq- 21 x^{2}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle 3\geq-21\cdot13^{2}\)\(\displaystyle 3\geq-21\cdot169\)\(\displaystyle 3\geq-3549\)

Since \(\displaystyle 3\)is greater than\(\displaystyle -3549\)the point is included in the inequality.

Example Question #306 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(42,-47\right)\) included in the inequality\(\displaystyle y\geq- 26 x^{4}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -47\geq-26\cdot42^{4}\)\(\displaystyle -47\geq-26\cdot3111696\)\(\displaystyle -47\geq-80904096\)

Since \(\displaystyle -47\)is greater than\(\displaystyle -80904096\)the point is included in the inequality.

Example Question #307 : Reasoning With Equations & Inequalities

Is the point \(\displaystyle \left(4,-26\right)\) included in the inequality\(\displaystyle y\geq- 4 x^{5}\) ?

Possible Answers:

No

Yes

Correct answer:

Yes

Explanation:

To see if the point is included in the inequality, we need to plug in the \(\displaystyle \uptext{x}\) value.\(\displaystyle -26\geq-4\cdot4^{5}\)\(\displaystyle -26\geq-4\cdot1024\)\(\displaystyle -26\geq-4096\)

Since \(\displaystyle -26\)is greater than\(\displaystyle -4096\)the point is included in the inequality.
