Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.

Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Answers

Answer 1

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°

I need 3 reasons why it is important to keep gorillas from becoming extinct. I'll give brainliest. I know that this isnt math but more people answer questions that are in math so... yea

Answers

Answer:

1. gorillas are able to spread the seeds of larger fruits that other, smaller animals are incapable of consuming. When gorillas consume a fruit and later expel the seeds, they are helping to perpetuate diverse, supportive ecosystems.

2. The forest will never be same if the gorillas are gone. Illegal coltan mines (minerals used in smart phone and computer production) are controlled by militia in the gorilla habitat (DRC) and contribute to habitat destruction and poaching.

3. Many local indigenous tribes and communities living alongside the gorilla habitat consider the gorillas to be their patron gods. The Kisimba clan (Bahumba) believe they descended from the gorillas. Their traditional tale tells a story of a gorilla rescuing a man that was lost and stuck high up in a tree. To save the man, a gorilla climbed up the tree and gently placed him on his silver back before carrying him back to safety.

Step-by-step explanation:

Ultimately we cant let gorillas go for much more reasons then just these 3 and they are used for so much in all of their respected environments.
