Algebra<em> - Algebra is one of the broad areas of mathematics. Roughly speaking, algebra is the study of mathematical symbols and the rules for manipulating these symbols in formulas; it is a unifying thread of almost all mathematics</em>

Division <em>- Division, otherwise known as the inverse of multiplication separates a certain number into what it has been divided by.</em>

Despite booming new car sales with their cha-ching

Elena-2011 [213]

Answer to the 1st question: 8 years

Answer to the 2nd question: The year 2022

=======================================================

Further explanation:

x = number of years after 2008

y = average price of a new car

The prices are going up by $1250 per year on average. This is the slope because the slope is the rate of change. So m = 1250.

The y intercept is b = 30100 as this is the price in 2008.

This leads us to go from y = mx+b to y = 1250x+30100

Plug in x = 0 and you should get y = 30100.

Also, plugging x = 6 into the equation leads to y = 37600 to help confirm things.

-----------------

Next, we plug in y = 47600 and solve for x.

y = 1250x+30100

47600 = 1250x+30100

47600-30100 = 1250x

17500 = 1250x

1250x = 17500

x = 17500/1250

x = 14

This means 14 years after the year 2008 is when the average new car price will be $47,600.

2008+14 = 2022

2022-2014 = 8

Therefore, <u>8 years</u> after 2014 (aka the <u>the year 2022</u>) is when the new car average price will be $47,600.

Graph the system of inequalities. Show at least two points for each inequality. (Lesson 1.08)

rjkz [21]

The inequalities and the points are

y + 2 ≤ 5x: (5, -2) and (10, 1)
y + x > -4: (5, -2) and (10, 1)
y ≤ 1/3x: (5, -2) and (10, 1))

<h3>How to graph the system of inequalities?</h3>

The system of inequalities is given as:

y + 2 ≤ 5x

y + x > -4

y ≤ 1/3x

Next, we plot each inequality in the system of inequalities using a graphing calculator

See attachment for the graph of the system of inequalities y + 2 ≤ 5x, y + x > -4 and y ≤ 1/3x

From the attached graph, we have the following points:

y + 2 ≤ 5x: (5, -2) and (10, 1)

y + x > -4: (5, -2) and (10, 1)

y ≤ 1/3x: (5, -2) and (10, 1)
