The difference after the subtraction is: 2a³ + 10a² - 5a - 4
What is a polynomial equation?A polynomial is an expression which has one or more of its variables with a power of at least 2 degrees. It can be expressed in form of a term.
Therefore, a polynomial equation is a means of expressing an expression with terms and on variable with a degree of 2 or more.
To find the difference by subtracting the polynomials, we have:
4a³ + 6a² - 11a - 3 - (2a³ - 4a² - 6a + 1) = 4a³ + 6a² - 11a - 3 - 2a³ + 4a² + 6a - 1
collecting like terms,
4a³ - 2a³ + 6a² + 4a² - 11a + 6a - 3 - 1 = 2a³ + 10a² - 5a - 4
Therefore, the difference by subtracting the two polynomials is:

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 6 ) and (x₂, y₂ ) = (8, 4 )
m = [tex]\frac{4-6}{8-3}[/tex] = [tex]\frac{-2}{5}[/tex] = - [tex]\frac{2}{5}[/tex] , then
y = - [tex]\frac{2}{5}[/tex] x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (8, 4 ) , then
4 = - [tex]\frac{2}{5}[/tex] (8) + c = - [tex]\frac{16}{5}[/tex] + c ( add [tex]\frac{16}{5}[/tex] to both sides )
[tex]\frac{20}{5}[/tex] + [tex]\frac{16}{5}[/tex] = c , that is

Triangle ABC is being enlarged using a scale factor of 2 and the origin as the centre to give triangle A'B'C'. Work out the coordinates of A' and B'. -10-9-8-7-6-5- 3- RE 2+ ¹C B .... 0 1-2-3-4-5-6-7-8 11 21 -3- 4 +5+ 6- -7- -8- -9- -10+
Answer:
Triangle ABC is being enlarged using a scale factor of 2 and the origin as the center to give triangle A'B'C'. To find the coordinates of A' and B', we will have to multiply each of the x and y coordinates of A and B by the scale factor of 2.
The coordinates of A are (-5, -6) and the coordinates of B are (2, 3)
The coordinates of A' will be (-52, -62) = (-10, -12)
The coordinates of B' will be (22, 32) = (4, 6)
So the coordinates of A' are (-10, -12) and the coordinates of B' are (4, 6).
ten slips of paper, numbered 1 through 10, are placed in a bag. if three slips are chosen at random from the bag without replacement and one of the slips chosen is numbered 7, what is the sum of numbers on the three chosen slips of paper? (1) the sum of two of the numbers chosen is 16. (2) the sum of two of the numbers chosen is 14.
The sum of the numbers on the three chosen slips of paper is either 21 or 23 in both the given cases.
We are given that one of the slips chosen is numbered 7, so the only possible sums of the remaining two slips are:
16 = 7 + 9
14 = 7 + 7
In the statement (1), the sum of two of the numbers chosen is 16, which means that the remaining two slips are 7 and 9. So the sum of the numbers on the three chosen slips of paper is 7 + 9 + 7 = 23.
In the statement (2), the sum of two of the numbers chosen is 14, which means that the remaining two slips are 7 and 7. So the sum of the numbers on the three chosen slips of paper is 7 + 7 + 7 = 21.
Hence, we get that in both cases, the sum of the numbers on the three chosen slips of paper is either 21 or 23.

What is the rate of change?The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" (ROC) is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line.
Given The table shows the distance Carol traveled after various numbers of minutes,
Input Output
2 1/6
3 17/48
4 13/24
5 35/48
6 11/12
Here, the output values from 1/6 to 11/12 indicate the distance in miles whereas the input values from 2 to 6 describe the time in minutes.
by utilizing the first two sets of input-output numbers, calculating the rate of change
Relative change = change in distance/change in time
(17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles per minute
Hence the rate of change is 3/16 miles per minute.

Whay is the y intercept of these two points: (-1,-5) and (6,0)?
The y-intercept of a line is the point at which the line crosses the y-axis. This means that the x-coordinate of the point is 0.
To find the equation of a line passing through two points, we use the slope-intercept form of the equation of a line: y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the y-intercept of a line passing through two points, we can use the slope-intercept form of the equation of a line and the coordinates of the two points:
(y1, y2) = m(x1, x2) + b
m = (y2-y1)/(x2-x1)
In this case, the two points are (-1,-5) and (6,0)
m = (0-(-5))/(6-(-1)) = 5/7
We can substitute the slope in the slope-intercept form of the equation of a line:
y = mx + b
so we can substitute point (-1,-5) in the equation and solve for b
-5 = (5/7)*(-1) + b
b= -5 + (5/7) = -5 + 0.7142857142857143
So, the y-intercept of the line passing through the two points (-1,-5) and (6,0) is -4.2857142857142865

A ball freely falling at 20 m/s will in the next second have a speed of ______. 30 m/s. What two units of measurement are necessary for describing speed?
Meters and seconds are the two units of measurement required to describe speed.
A ball freely falling at 20 m/s will in the next second have a speed of 30 m/s.This is because the speed of a freely falling item rises by 9.8 m/s per second owing to gravity's acceleration. The ball begins at a speed of 20 m/s and adds 9.8 m/s to its initial speed after one second, ending in a final speed of 20 + 9.8 = 29.8 m/s (approx. 30 m/s).
Meters and seconds are the two units of measurement required to describe speed. These units are used to calculate the distance travelled by an item as well as the time it takes to traverse that distance. In this scenario, the ball's speed is measured in metres per second (m/s), which is the distance the ball travels in one second.

The first company offered him a weekly salary of $ 800.00 $800.00 plus a commission of $ 0.30 $0.30 for each cupcake he sells. The second company offered him a weekly salary of $ 350.00 $350.00 plus a commission of $ 1.30 $1.30 for each cupcake he sells. How many cupcakes must John sell each week for the total pay from each company to be the same?
PLEASE ANSWER FAST WORTH 92 POINTS
Answer:
450 cupcakes
Step-by-step explanation:
Let x be the number of cupcakes sold for John's total pay to be the same for both companies
For the first company
Salary = $800/week
Commission is $0.30 per cupcake
For sales of x cupcakes, total commission = 0.30x
Total pay = Weekly salary + Total commission from sales
Total Pay = 800+ 0.3x
For the second company
Salary = 350 /week
Commission: $1.30 per cupcake
For sales of x cupcakes, total commission = 1.30x
Total Pay = Weekly salary + Total commission from sales
Total Pay = 350 + 1.3x
If both pay must be he same,
800 + 0.3x = 350 + 1.3x
800-350 = 1.3x - 0.3x
450 = 1x
x = 450 cupcakes ANSWER
Answer: 450
Step-by-step explanation:
If we let x and y represent the number of cupcakes John sells and his total weekly income, respectively, we get the following system of equations.
=0.35x+845
=1.4x+372.5
Since both equations are solved for y, any substitution for y will result in the following
211.4 x+372.5&=0.35
x+845
1.4x+372.5
=0.35x+845
Solving for x will give us the number of cupcakes John needs to sell weekly for each paycheck to be the same. Doing so, we get
1.4 x+372.5&=0.35 x+845
1.05 x&=472.5x=450
1.4x+372.5
1.05x
x
=0.35x+845
=472.5
=450
Therefore, John needs to sell 450450 cupcakes each week for both salaries to be the same.
height is an example of a variable that uses the _____ scale.
Height is an example of a variable that uses the ratio scale.
Hence, option (a) is the correct choice.
Weight, height, and distance are all ratio variables. The ratio scale allows you to add, subtract, divide, and multiply data. Ratio scales are further distinguished from interval scales by the presence of a 'true zero'.
Height is an excellent example of a measuring scale based on a ratio. It is not nominal or ordinal since each change in the height unit (inches, metres, feet, etc.) has a standard distance between them, and it is not interval because height has a genuine zero.
Height, for example, is ratio data. There is no such thing as negative height. If the height of an item is 0, there is no object. This is not the same as talking about temperature.
