The value of variable x that makes -4x-(-10 - 8x) = -(12x-14) true is 1/4. thus, option c is correct.

An equation's unknown numerical value is represented by a symbol (typically a letter) called a variable in algebra. X and Y, which are real-number unknowns, as well as z, which are complex-number unknowns, as well as t, r, and s are frequently used variables (arc length).

Given

-4x-(-10 - 8x) = -(12x-14)

-4x + 10 + 8x = -12x + 14

4x + 10 = 14 - 12x

4x + 12x = 14 - 10

16x = 4

x = 4/16

x = 1/4

Thus, Option C is correct, x = 1/4

Step-by-step explanation:

No there ratios are not the same Kenji's ratio is 3:5 while Lar's ratio is 4:6 you can find if a ratio is equivalent or not by multiplying each ratio together for example a ratio 3:5 would be 3 times 5 which equals 15.

On solving the system of linear equations y = -x + 2 and 3x - y = 6, the point of solution is obtained as option 3: (2,0).

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

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

3x - y = 6....(2)

Writing equation (2) in standard form y = mx + b -

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

Now solving the equation (1) and (3) by adding -

y + (-y) = -x + 2 + (-3x + 6)

0 = -4x + 8

4x = 8

x = 2

Now, substituting the value of x = 2 in equation (1) -

y = -x + 2

y = -(2) + 2

y = -2 + 2

y = 0

Therefore, the values for x and y are 0 and 2 respectively.

distance between 2 points = root (x1-x2)²+(y1-y2)²

so root (-2-2)²+(5--3)² = 8.994 ≈ 9 units

Answer:

  Emille's soccer team

Step-by-step explanation:

You want to know the higher win/loss ratio of Emille's 9/12 or Grant's 10/15.

One way to compare the fractions is to subtract one from the other:

  9/12 -10/15 = (9·15 -12·10)/(12·15) = (135 -120)/(12·15) = 1/12

This is a positive number, so the fraction 9/12 is higher.

Emille's team's win/loss ratio is higher because subtracting the win/loss ratio of Grant's team gives a positive result.

__

Additional comment

Grant's team's ratio reduces to 2/3, which can be expressed as 8/12. This is clearly lower than 9/12.

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 3 ← is in slope- intercept form

with y- intercept c = 3

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

to find the equation of the line from the table

y = mx + c

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 15) and (x₂, y₂ ) = (10, 66) ← 2 ordered pairs from the table

m = [tex]\frac{66-15}{10-4}[/tex] = [tex]\frac{51}{6}[/tex] = 8.5 , then

y = 8.5x + c ← is the partial equation

to find c substitute any ordered pair from the table into the partial equation

using (6, 32 ) , then

32 = 8.5(6) + c = 51 + c ( subtract 51 from both sides )

- 19 = c ← the y- intercept

to calculate the distance between the y- intercepts c = 3 and c = - 19

find the absolute value of the difference, that is

distance = | - 19 - 3 | = | - 22 | = | 22 | = 22

or

distance = | 3 - (- 19) | = | 3 + 19 | = | 22 | = 22

then distance between the y- intercepts is 22 units

Marcella is incorrect. A trapezoid is a quadrilateral with exactly one pair of parallel sides, while a rectangle is a quadrilateral with four right angles. Since the definition of a rectangle requires four right angles, it is not possible for a trapezoid to be a rectangle as they have only one pair of parallel sides.

A square is a special type of rectangle, where all four sides are of equal length. Therefore, it is possible for a square to be a rectangle.

The mathematical proof is given below. Then the claims are correct.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The triangle ΔABC is a right-angle triangle. And line CD is perpendicular to line AB.

In triangles ΔABC, ΔACD, and ΔCDB, we have

∠ACB = ∠ADC = ∠BDC                     (Right angle)

∠ABC = ∠ACD = ∠CBD                     (Corresponding angles)

Answer: The answer is D.369 miles

Step-by-step explanation:

To solve this problem, you can use the formula: distance = rate x time.

We know that Chris and Nikoletta start at the same point, and they drive in opposite directions, so the total distance between them is the sum of the distance that each of them travels.

If Chris travels at a rate of 54 mph, and he drives for 3 hours, then the distance he travels is:

distance = rate x time = 54 mph x 3 hours = 162 miles

Similarly, if Nikoletta travels at a rate of 69 mph, and she drives for 3 hours, then the distance she travels is:

distance = rate x time = 69 mph x 3 hours = 207 miles

So the total distance between Chris and Nikoletta is the sum of the distance that each of them travels:

distance = 162 miles + 207 miles = 369 miles.

So the answer is D.369 miles

The equation of the line that passes through the points (0, -1) and (1, 2) is y = 3x - 1.

The equation of a straight line in slope - intercept form is -

y = mx + c

{m} - slope.

{c} - intercept along the y - axis.

Given is the line passes through the y - axis at (0, -1) and through the point (1, 2).

We can write the slope of the line as -

m = (2 + 1)/(1 - 0)

m = 3

So, we can write the equation as -

y = 3x + c

For the point (0, - 1), we can write -

- 1 = 3 x 0 + c

c = - 1

Therefore, the equation of the line that passes through the points (0, -1) and (1, 2) is y = 3x - 1.

The number of tickets that she has bought is 6000-5520 = 480 tickets.

What is probability ?

Probability is a measure of the likelihood of a certain event happening. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. A probability of 0.5 represents an event that is equally likely to happen or not happen, while a probability of 0.8 represents an event that is more likely to happen than not happen.

Probability can be expressed as a decimal, fraction, or percentage. For example, a probability of 0.5 can also be expressed as 1/2 or 50%.

If the probability of her winning the prize in a lottery is 0.08, then the probability of her not winning the prize is 1-0.08 = 0.92.

If 6000 tickets are sold, and the probability of her not winning the prize is 0.92, then the number of tickets that she has not bought is 0.92*6000 = 5520.

Therefore, the number of tickets that she has bought is 6000-5520 = 480 tickets.

The equation of the vertical line that passes through (-4, 3) is x = -4.

This means that all points on the line have an x-coordinate of -4 and a y-coordinate of any value. To prove this, we can plug in -4 for x in the standard form of an equation of a line: y = mx + b. Since the line is vertical, the slope (m) is undefined, so the equation becomes 0 = 0 + b, which simplifies to b = 0.  Since m is undefined, the equation simplifies to just x1 = -4, meaning that the x-intercept of the line is -4. The equation of the line is then y = 0x - 4, which simplifies to y = -4. Therefore, the equation of the vertical line that passes through (-4, 3) is x = -4

m =-1/5 and b =5 units.

The slope of a line determines how steep it is. A characteristic of a color filter equation is a gradient overflow. The horizontal distance disparities (run) between two points are divided by the average vertical differences (rise) between the exact two points to determine the slope. The equation y = mx + b, which is known as the hill type equation, is used to express the fixed path issue. If grading is m, a = b, and the line's y-intercept is located there (0, b).

Smoothing a curve in Prism involves reducing the amount of "noise" that can be seen in a graph. This can be done by applying a low-pass filter to the data or by using a smoothing algorithm.

Low-pass filters will reduce the amount of high-frequency fluctuations in the data, while smoothing algorithms will identify patterns in the data and smooth out the irregularities. In both cases, the data points are changed in a way that reduces the amount of variability in the data while still preserving the overall shape of the curve.

Smoothing can help to make the data more readable and make it easier to identify trends in the data. Smoothing is a valuable tool for visualizing data, but should be used carefully to ensure that the true shape of the curve is not distorted.
