A certain car averages 15 kilometers per liter of gasoline. How many meters can the car travel on one mililiter of gasoline

Answer: x = 2, y = -3

Step-by-step explanation: From the question,

-3x -3y = 3 ---------- this becomes the first equation

Make y the subject

-3y = 3 + 3x

y = (3 + 3x)/ -3  ----------this becomes our second equation

Substitute the value of y into the first equation

-3x -3(3 + 3x) = 3

-3x -9 + 9x = 3

Collect like terms

-3x + 9x = 3 + 9

6x = 12

Divide both sides by 6

6x/ 6 = 12/ 6

x = 2

Substitute x = 2 into the second equation to find y

y = (3 + 3(2) )/ -3

y = ( 3 + 6) / -3

y = 9/ -3

y = -3

The secant segment theorem states that If two secant segments intersect outside a circle, then the product of the secant segment with its external portion equals the product of the other secant segment with its external portion.

A secant is a line on the circle that connects exactly two distinct points on the curve. Secant is not a chord but a chord is part of a secant. Two different secants can intersect each other internally or externally.

Further, the secant segment theorem defines two more theorems or properties and they are:-

Arcs are line segment that is part of the circumference of a circle. It is like a smooth curve that joins two points. If an arc is of exactly the half-length of circumference then it is called a semicircular arc.

There are many different types of inequality, but generally, they can be grouped into two main categories economic inequality and social inequality.

Economic inequality: This refers to the unequal distribution of wealth, income, and resources among individuals or groups within a society. Economic inequality can manifest in various forms, such as income inequality, wealth inequality, and poverty.

Social inequality: This refers to the unequal distribution of social status, power, and privilege among individuals or groups within a society. Social inequality can manifest in various forms, such as discrimination, prejudice, and bias, which can limit opportunities and access to resources for certain groups.

It's important to note that these two types of inequality are often interconnected and can have a significant impact on individuals and groups, leading to reduced opportunities, access to resources, and lower quality of life.

The following are the 5 steps in solving a rational inequality: simplifying the inequality, factoring the numerator and denominator of the inequality, set the numerator and denominator equal to zero.

Solving a rational inequality involves isolating the variable and determining the range of values that make the inequality true.

Simplify the inequality by clearing any fractions: This can be done by multiplying both sides of the inequality by the least common multiple (LCM) of the denominators of the fractions.

Factor the numerator and denominator of the inequality: This can be done to cancel out any common factors between the numerator and denominator.

Set the numerator and denominator equal to zero and solve for the zeros: This can be done to find the values of the variable that make the numerator and denominator equal to zero.

Test the zeros and any critical values: This can be done by substituting the zeros and critical values back into the inequality and determining if they make the inequality true or false.

Plot the solution on the number line: This can be done by plotting the zeros and critical values on a number line and shading the region that makes the inequality true.

These ratios are different because they express the number of laps for two different numbers of hours.

To better understand how these ratios compare, let's simplify the second ratio:

192 laps/ 8 hours = 24, which means the ratio would be 24 laps per hour

This means that the ratios express the same number of laps per hour.

Basically, the two ratios tell us the number of laps but using different hours. In this way, the first ratio expresses the number of laps in only one hour, while the second ratio amplifies this ratio to eight hours.

According to the table for a $150,000 mortgage, Lastri's credit score needs to improve by 62 points for her to take a mortgage for $150,000.

The credit score refers to an individual's or entity's creditworthiness rating.

The credit score predicts a person's credit behavior and ability to repay credit.

Financial institutions and lenders use the credit score to determine the amount of credit to offer a borrower, the attached credit risks, and the accompanying interest rate, including monthly payments.

Annual mortgage payments Lastri can afford = $13,900

Monthly payment = $1,158 ($13,900 ÷ 12)

Current credit score = 498

Minimum credit score for a monthly payment of $1,158 = 560

Additional credit score improvement = 62 (560 -498)

Thus, for Lastri to qualify for a $150,000 mortgage, her FICO credit score must improve by 62 points.

To determine if three points are in a straight line in 3D, you can calculate the vector between the first two points and then check if the third point is in the same direction as the vector.

Straight line is a line that extends infinitely in two opposite directions and has no curves or bends. It is the shortest distance between two points and is the basic form of geometry. A straight line is composed of two end points and all the points in between that make up the line. Straight lines are used to create shapes and constructions in mathematics, science and engineering.

If the dot product of the vector and the point is 0, then the three points are in a straight line. Alternatively, you can calculate the area of the triangle formed by the three points and if it is 0, then the points are in a straight line. Another option is to calculate the determinant of the matrix formed by the three points and if it is 0, then the points are in a straight line. Finally, you can calculate the angle between the two vectors formed by the three points and if it is 0, then the points are in a straight line.

The image point of P(x,y) = ( 6 , 5 ) after applying a horizontal reflection is P'(x,y) = (1, 5).

In geometry, a rigid transformation is a transformation applied onto a geometric object such that Euclidean distance in every point of it is conserved. Translations are examples of rigid transformations and are defined by this formula:

P'(x,y) = P(x,y) + T(x,y)                    (1)

Where:

P(x,y) - Original point

T(x,y) - Translation vector

P'(x,y) - Image point

If we know that P(x,y) = (6, 5) and T(x,y) = (5, 0), then the image point is:

P'(x,y) = (6, 5) + (5, 0)

P'(x,y) = (1, -6)

The reasonable estimate of the probability that it is sunny tomorrow is 25%.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Probability of an event is calculated by dividing the number of desirable outcomes by the total number of events possible.

From the graph, we have,

Number of days weather is sunny = 3

Total number of days = Days weather is sunny + Days weather is cloudy + Days weather is rainy + Days weather is snowy

Total number of days = 3 + 5 + 2 + 2 = 12

Probability that weather is sunny = 3 / 12 = 1/4 = 0.25 = 25%

Hence there is a 25% probability that weather is sunny.

The labour cost per hour charged by the technician for the laptop is $124.91

Here we see that it cost Sarah $54 dollars for the parts. Now, the technician charged her $585.25.

Since nothing else is mentioned, we will assume that the technician charged Sarah only for the parts and their labour hours.

Hence after deducting the charge for the computer parts, we can get the cost for the labour. We know the labour hours to be 4.25 hours. We don't know the labour cost, which is to be found.

Let the cost of labour per hour be $x

Hence the labour cost will be $4.25x

Adding the cost of parts will give us the charged amount. Hence we get

4.25x + 54 = 585

or, 4.25x = 531

or, x = 531/4.25

or, x = 124.941

Hence the cost per hour is $124.941

given d is directly proportional to t² , then the equation relating them is

d = kt² ← k is the constant of proportion

to find k use the condition , the ball falls 80 m in 4 seconds , then

80 = k × 4² = 16k  ( divide both sides by 16 )

5 = k
