Karl set out to alaska on his truck the amount of fuel remaining in hi truck tank in liters as a function of distance driven in kilometers is graphed
What distance did Karl travel by the time he had 200 liters of fuel

Answers

Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Why it is and what is distance?

To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.

From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.

Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.

Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.

In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *

Answers

$24

(ignore this i don’t have enough characters )

Answer:

57 dollars

Step-by-step explanation:

1. Solving the 25% discount

25% = .25

80 x .25 = $20

80 - 20 = $60

** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.

2. Solving the 5% Tax

5% = .05

$60 x .05 = 3

$60 + 3 = $63

**Adding tax to the discounted price

Write the equation of the line that passes through the points (-1,3) and (-6, -7).

line.

Answers

Answer:

y - 3 = 2(x + 1)

Step-by-step explanation:

First, use rise over run to find the slope

(y2 - y1) / (x2 - x1)

(3 + 7) / (-1 + 6)

10 / 5

= 2

Now, plug in the slope and a point into the point slope formula:

y - y1 = m(x - x1)

y - 3 = 2(x + 1)

So, the equation in point slope form is y - 3 = 2(x + 1)

Calculate 48 x 3/8 choose the numbers to complete the equation

Answers

Answer:

1. Choose: 3

2. Choose: 144

3. Choose: 18

Step-by-step explanation:

The first thing you do is multiply 48 * 3/8= 18.  Then multiply 48 * 1/8= 6.  Then divide both answers to get 3, so 48 * 1/8 * 3.

Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).

Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

Find the value of the missing Angles:

Answers

Answer:

Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32

[tex]2x^2-20x=x^{2} -19[/tex]

Answers

Answer:

x = 1, x = 19

Step-by-step explanation:

Given

2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )

x² - 20x + 19 = 0 ← in standard form

(x - 1)(x - 19) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 19 = 0 ⇒ x = 19

x1 = 1 x2 = 19 if I’m correct

Step-by-step explanation:

Answer:

You have to write the number-line out man. However, the answer is -2

Step-by-step explanation:

When solving problems like these, knowledge or integers and whole numbers are important. First, find the absolute values of both numbers.

Absolute value of -6: 6

Absolute value of 4: 4

Subtract the values: 6 - 4 = (Positive 2)

THEN, look at the number with the Greater Absolute value. In this case, it is -6. Because -6 has the greater absolute value, your answer should be the connotation of that number. IN THIS CASE, the number with the greater absolute value, -6, has a negative sign. Therefore, your answer should be negative. Your answer is -2.

Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. Courtney is bringing a number of snacks. If Chelsea brought 16 snacks, how many did Courtney bring?​

Answers

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means 2 · (a number)

If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.

In order to find out, we have to divide.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.

Hope this helped! :)

What is Inequality?

a relationship between two expressions or values that are not equal to each other is called 'inequality.

We need to check How is a system of two linear inequalities in two variables different to a system of two linear equations in two variables

A linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality.

A system of linear equations is usually a set of two linear equations with two variables.

A system of two linear inequalities is different from a system of two linear equations. A system of two linear inequalities always has more than one solution while there can only be one solution to a system of two linear equations.

Hence, option D is correct. A system of two linear inequalities always has more than one solution while there can only be one solution to a system of two linear equations.

True or False: An asymptote is a line in which a graph gets close to but never crosses.
True
False

Answers

Answer:

True

Step-by-step explanation:

An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.

The statement is true.

What is an asymptote?

Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.

An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.
