Question 3

Ellen drew a graph showing the solution to an inequality. Expand Image Which inequality does Ellen’s graph show the solution to?

Revolt · Accepted Answer

B: negative 3 point 2 5 is greater than negative 2 point 5 plus r

Question 4

Which inequality represents the sentence given? The difference of negative 3 point 2 and the sum of a number and 19 point 1 is at most 14 point 2

Revolt · Accepted Answer

B: negative 3 point 2 minus open paren x plus 19 point 1 close paren is less than or equal to 14 point 2

Question 5

Allen is running a marathon. He would like to finish the race in under 5 point 5 hours. He has already run 3 hours. The inequality 3 plus t is less than 5 point 5 represents the situation. Which number line shows how much longer Allen can run and still meet his goal?

Revolt · Accepted Answer

A: Image with description A number line ranges from 0 to 3 by one halves. The number line represents the variable t. An open circle is on 2 point 5. A ray is drawn from that circle pointing to the left.

Question 6

Rico represents the inequality negative 3 times open paren the fraction with numerator 8 and denominator x minus 5 close paren is greater than negative 16 with the sentence “The product of negative 3 and the quotient of 8 and the difference of a number and 5 is at least negative 16 ” Which describes Rico’s error?

Revolt · Accepted Answer

D: The inequality symbol is translated incorrectly. The words “at least” should be represented as greater than or equal to instead of greater than.

Question 7

Which graph represents the solution set of the inequality −9>x ?

Revolt · Accepted Answer

B: Image with description A number line ranges from negative 13 to negative 7 by ones. An open circle is on negative 9. A ray is drawn from that circle pointing to the left.

Question 8

Kelly’s first four test grades of the period were 80 , 72 , 96 , and 88 Which inequality represents the grades she can earn on the fifth test to have a test average of no less than 80 ?

Revolt · Accepted Answer

C: g is greater than or equal to 64

Question 9

Michael is on page 28 of a 315 -page book. He must finish the book within the next 14 days.

What error did Michael make when he wrote this inequality to model the situation?

Revolt · Accepted Answer

C: He did not make the variable the minimum number of pages and should have solved  28 plus 14 p is greater than or equal to 315 .

Question 10

Solve the following inequality. 6.3⁢r<−45.36 Which graph shows the correct solution?

Revolt · Accepted Answer

D: Image with description A number line ranges from negative 7 point 7 to negative 6 point 8 by one tenths. An open circle is on negative 7 point 2. A ray is drawn from that circle pointing to the left.
