The slope of the line 3x - 4y = -12 is 3/4, obtained by dividing -3 by -4 after isolating y.

What is slope ?

Slope, also known as gradient, is a measure of the steepness of a line. It is the ratio of the change in the y-coordinate to the change in the x-coordinate between any two distinct points on the line. It is represented by the letter "m" in the slope-intercept form equation of a line y = mx + b, where m is the slope, x is the independent variable, y is the dependent variable and b is the y-intercept, the point where the line crosses the y-axis.

The slope of a line can be found by rearranging the equation to the slope-intercept form y = mx + b. To find the slope of the equation 3x - 4y = -12, you can divide both sides by -4 and then divide by 3.

3x - 4y = -12

-4y = -3x -12

y = (3/4)x +3

So , The slope of the line 3x - 4y = -12 is 3/4, obtained by dividing -3 by -4 after isolating y.

Particularly in statistics, there are many different mean types.Each mean is used to summarise a particular set of data, typically in order to assess the overall importance of that data set. A statistic known as the standard deviation describes the degree of variance or dispersion in a group of values.

What is percentange ?

Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%" (percent sign) and it's used to express a proportion or ratio. For example, if a student scored 80 out of 100 in an exam, the percentage score would be 80%, which means the student answered 80 out of 100 questions correctly.

A truth serum given to a subject is known to have a 91% reliability rate when the person is guilty and a 94% reliability rate when the person is innocent. This means that when the person is guilty, there is a 91% chance that the truth serum will indicate that the person is guilty, and a 9% chance of a false negative (indicating the person is innocent when they are guilty). Similarly, when the person is innocent, there is a 94% chance that the truth serum will indicate that the person is innocent, and a 6% chance of a false positive (indicating the person is guilty when they are innocent).

Since there are two complex conjugates as the roots of the quadratic equation 5x2 4x 3 0 there is no way to describe them in terms of real integers.

The roots can only be roughly calculated because they are irrational numbers.

Two complex conjugates, which are unable to be expressed in terms of real numbers, make up the roots of the quadratic equation 5x2 4x 3 0. Using the quadratic formula, the roots can be discovered. The coefficients of the equation are necessary for the formula, and in this example, they are a=5, b=4, and c=3. When the quadratic formula is used, two complex roots are produced, denoted by the expressions x1 = -1/5 + (16)/5i and x2 = -1/5 - (16)/5i. Since their roots are irrational integers, they can only be roughly calculated. When b2-4ac, the discriminant, is negative, complex roots are frequently discovered.

Before any taxes, deductions, and other adjustments, she earns $98.40 per week.

To calculate Talia's gross pay for a week, we need to know how many hours she works per day and her pay rate.

Gross pay refers to the total amount of money an employee earns before any deductions or taxes are taken out. It is the total amount of money earned by an employee for the hours worked, including any overtime or bonuses.

You've provided that information:

Talia works 6 hours per day on Fridays and Saturdays each week.

Her pay rate is $8.20 per hour.

First, we need to find out how many hours she works a week. As she works 6 hours on Friday and 6 hours on Saturday, the total hours she works in a week is 6 hours/day x 2 days/week = 12 hours/week.

Next, we need to multiply her hourly rate by the number of hours she works per week to find her gross pay. Her pay rate is $8.20/hour and she works 12 hours/week, so her gross pay is:

$8.20/hour x 12 hours/week = $98.40/week

So, Talia's gross pay for a week is $98.40.

Answer: The answer is the last one D.

Step-by-step explanation:

The value of x = 10 and y = 8.

The method of elimination is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

Equation 1
-2y = 2 - 3x
-2y + 3x = 2
3x - 2y = 2 .....(1)


Equation 2
-5y = 10 - 5x
-5y + 5x = 10
5x - 5y = 10
Taking 5 common we get,
5(x - y) = 5(2)
x - y = 2 .....(2)

On multiplying equation (2) by 3, we get

3x - 3y = 6 .....(3)

Adding equation (1) and (3),
 
       3x - 2y = 2
       3x - 3y = 6
     _____________
                y = 8
       
Putting the value of y in equation (2) we get,
x - 8 = 2
x = 2 + 8
x = 10

What is the Division?

Division is a mathematical operation used to find the number of times one number, known as the dividend, is contained within another number, known as the divisor. It is represented by the symbol "/" or the word "divided by". It is the inverse operation of multiplication.

To determine when the populations of Rock Hill and Greenville will be the same, we need to find the difference in population growth between the two cities and divide it by the difference in population growth rate. We can use the following formula:

(Population of Rock Hill - Population of Greenville) / (Population growth rate of Rock Hill - Population growth rate of Greenville) = Number of months until populations are equal

First, we will calculate the population growth rate of Rock Hill and Greenville:

Population growth rate of Rock Hill = (100 people move in) - (150 people move out) = -50 people/month

Population growth rate of Greenville = 200 people move in/month

Now we can use this information to calculate the number of months until the populations are equal:

(70,000 - 61,000) / (-50 - 200) = (9,000) / (-250) = 36

Answer:

  82°

Step-by-step explanation:

You want the unmarked remote interior angle of a triangle, given that one of them is 61°, and the exterior angle opposite is 143°.

The exterior angle is the sum of the remote interior angles:

  143° = 61° +∠B

  ∠B = 143° -61° . . . . subtract 61°

  ∠B = 82°

__

Additional comment

In case you don't remember the remote interior angles theorem, you can get the same result using angle relations you do remember:

The interior angle at A is the supplement of the exterior angle:

  ∠A = 180° -143°

When ∠A is added to the other two interior angles, the total is 180°:

  ∠A +∠B +61° = 180°

  (180° -143°) +∠B +61° = 180° . . . . . . use the above expression for ∠A

Rearranging this to give the value of angle B, we have ...

  ∠B = 180° -180° +143° -61°

  ∠B = 143° -61° = 82° . . . . . . as above

Another way to get there is to consider ...

  The sum of ∠B and 61° is supplementary to interior angle A (their total is 180°). The exterior angle 143° is supplementary to interior angle A. Two angles supplementary to the same angle are equal, so the sum of ∠B and 61° is equal to the exterior angle 143°.

As often seen on Brainly, and in poorly-edited math curriculum materials, the expression x2 is a badly-formatted version of x². It is often the result of a copy/paste operation in which the superscript text formatting is lost.

If you write this as x^a+b, it looks like b is added to the value of x^a. The expression above would be correctly written in plain text as x^(a+b), using parentheses to do the grouping that would otherwise be provided by the superscript font.
