Hey there!


2x + 1 < 5

SUBTRACT 1 to BOTH SIDES

2x + 1 - 1 < 5 - 1

SIMPLIFY IT!
2x < 5 - 1

2x < 4


DIVIDE 2 to BOTH SIDES

2x/2 < 4/2

SIMPLIFY IT!
x < 4/2

x < 2


Therefore, your answer is: x < 2

(The graph is down below)


Good luck on your assignment & enjoy your day!

Please help me on my discussion topic.i'll give you 20pts 
Crazy boy [7]

Artists such as Al Held, Bridget Riley etc are known for their abstract artwork or geometric artwork. Riley is famous for her optical artwork.

This art form is present among many cultures throughout the history both as decorative motifs and as art pieces themselves. Like in Islamic art, this art depicts religious figures. The optical art gives the viewer the impression of movement, hidden images, flashing and vibrating patterns. Basically it gives a disorienting effect.

Besides optical art, other abstract art forms are also famous. These imbibe a strong imagination and a sense of creativity in its viewers. This art form puts different colors, shapes, and textures together to create a finished piece that represents something in particular.

Yes, I appreciate this kind of art form because these forms are genuine and helps us understand the art patterns. Unlike the traditional form, these forms explore the relationships of forms/shapes and colors. Moreover, art always reflects culture. Therefore, abstract art is important because it is reflecting a culture that has been moving since last 2000 years.

a marina rents party boats for large social gatherings. They charge the following amounts for a 2 hour rental. 10 people for $16
Verdich [7]

Answer:

An equation that represents the data would be y=2.75x+137.50. The y-intercept of the graph is 137.50, which represents the base cost of a boat rental.  The slope of the graph is 2.75, which represents the rate, or cost per person.  If we use this equation to solve for the cost of boat rental for 75 people, we would get a total of $343.75.  A reason the marina might charge more for 75 people could be the need for a second boat and/or additional workers to handle the additional guests.  

Step-by-step explanation:

The problem gives you four sets of ordered pairs: (10, 165); (20, 192.50); (35, 233.75) and (50, 275).  Using these ordered pairs, you can either make a table, or use slope formula with two points to determine the rate of change.  For example, (192.50-165)/(20-10)= 2.75, which represents the slope or cost per person.  To find the y-intercept, or base cost to rent the boat, subtract the cost for 10 people ($27.50) from the $165 rental charge to get $137.50.  In order to find the cost for 75 people, you would plug in 75 for the variable 'x' and solve for 'y', which gives us $343.75.  Since the actual cost is different, we have to assume that there are additional fees associated with a certain number of people.
