Chandler, Jamal, Allison, and Qi are given the following problem. In 1982, Wayne Gretsky set a record for the greatest number of

hockey goals in one season with 92 goals. If a player has scored 60 goals this season and averages 2 goals per game, how many additional games must he play to break the record? Each student writes an inequality to represent the situation. Chandler wrote 60 + 2g ≥ 92 Jamal wrote 60 + 2g > 92 Allison wrote 60 + 2g < 92 Qi wrote 60 + 2g ≤ 92 Whose inequality is CORRECT? A. Qi B. Chandler C. Allison D. Jamal

Answer:

The correct answer is B.

Step-by-step explanation:

Since Chandler, Jamal, Allison, and Qi are given the following problem: "In 1982, Wayne Gretsky set a record for the greatest number of hockey goals in one season with 92 goals. If a player has scored 60 goals this season and averages 2 goals per game, how many additional games must he play to break the record? ", And each student writes an inequality to represent the situation:

Chandler wrote 60 + 2g ≥ 92

Jamal wrote 60 + 2g> 92

Allison wrote 60 + 2g <92

Qi wrote 60 + 2g ≤ 92

To determine whose inequality is correct, the following calculation must be performed:

92 - 60 = 32

32/2 = 16

Chandler: 60 + 2x16 ≥ 92

Thus, Chandler wrote the correct option.

Ivanshal [37]

Answer:


Step-by-step explanation:

Statement                                                                        Reason

1.∠4 is an exterior angle of ΔABC                                  Given

2.∠3 and∠4 form a linear pair                                 Linear pair theorem

3.∠3 is supplementary to ∠4                        Property of supplementary angle

4.m∠3+m∠4=180°                                        Definition of supplementary angle

5.m∠1+m∠2+m∠3=180°                               Triangle sum theorem

6.m∠1+m∠2+m∠3=m∠3+m∠4                     From step 4 and 5

Factorise 1-a^2 b^2​
DerKrebs [107]

Hi there.

Thanks for using Brainly!

First, let's rewrite to make this problem easier.

1^2 - a^2b^2

Then we must multiply the terms with equal exponents with their bases.

1^2-(ab)^2

Using the factor: a^2 - b^2=(a-b)(a+b)

We can factor using that expression.

(1-ab) x (1+ab)

After factoring, this has been our solution.

Solution: (1-ab) x (1+ab)

Thanks for using Brainly!
