Go to your math tools and open the Graph tool to graph Gwen’s and Keith’s equations. Be sure to remove Tristan’s equation before adding Keith’s equation.


Do the two lines intersect? Why or why not? What does this mean in terms of the situation? If they intersect, at what point do they intersect and what does this point mean in terms of the situation?

gwen’s: y = 100 + 10x

keith's: y = 10x

Answers

The lines will never intersecting as they are parallel lines because the slope of the lines is equal.

Given that,
y = 100 + 10x and  y = 10x
To justify whether the two lines intersect each other or not,

What is a line?

A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.

Here,
y = 10 + 10x,
The slope of the equation is m1 = 10
y = 10
The slope of the above equation is m2 = 10
Since the slope of both lines is an equation, it implies that the lines are parallel to each other it will not intersect at any point.

Thus, the lines will never intersect as they are parallel lines because the slope of the lines is equal.

The value of a car decreases by 20 percent per year. Mr. Sing purchases a $22,000 automobile. What is the value of the car at the end of the second year?
A- $14,080
B- $17,600
C- $19,800
D- $26,400

Answers

Answer:A

Step-by-step explanation:cause if you know a lot about cars you would know

Answer:

A- $14,080

Step-by-step explanation:

At end of first year:

$22,000 will decrease by 20%. It means to subtract 20% of 22,000 from 22,000.

20% of 22,000 is  

0.2 x 22,000 = 4,400

Now,  

22,000 - 4,400 = 17,600

At end of second year:

$17,600 will decrease by 20%. It means to subtract 20% of 17,600 from 17,600.

20% of 17,600 is  

0.2 x 17,600 = 3520

Now,  

17,600 - 3,520 = 14,080

Hence, $14,080 is the value of the car at the end of 2 years.

Answers

Answer:

a. 6Pack of paint brushes for $12.99

b. 5 classes for $64.99

c. 12 pack of paper plates

Step-by-step explanation:

a.

I could buy a 6 pack of paint brushes for $ 12.99

or

buy 6 individual brushes for the price of $ 2.19 each.

6 x $2.19 = $13.14

first option is cheaper

b.

10 classes for s total of $150

$150 ÷ 10 = $15 (price per class)

5 classes for $64.99

$64.99 ÷ 5 = $12.998 (price per class)

c.

12 pack of paper plates for $2.29

25 pack for $4.99

$2.29 ÷ 12 = $0.1908 (price of one plate)

$4.99 ÷ 25 = $0.1996 (price for one plate)
