The difference in the given functions is 2x^3 + 6x^2 -8x + 1
Difference of functionsGiven the following function a shown
f(x)= 2x^3 + 6x^2 -5x - 3
g(x)= 3x-4
Take the difference
(f-g)(x) = f(x) - g(x)
Substitute
(f-g)(x) = 2x^3 + 6x^2 -5x - 3 - (3x - 4)
Expand
(f-g)(x) = 2x^3 + 6x^2 -5x - 3 - 3x + 4
(f-g)(x) = 2x^3 + 6x^2 -8x + 1
Hence the difference in the given functions is 2x^3 + 6x^2 -8x + 1

What is the y - cordanate of the point that divides the directed line segment from j to k into a ratio of 2:3
The coordinate of point P that divides the line segment into 2 parts and 3 parts is (-5,5).
Let's call the point that divides the line segment point P.
Point P divides the line segment into a ratio of 2:3
What is the ratio of 2:3?The ratio of 2:3 means we are dividing the line segment into 2+3=5 equal parts.
The horizontal distance between the two coordinates is 5.
The vertical distance between the two coordinates is 10.
Dividing both vertical and horizontal distance into five equal parts, we have a horizontal distance of 1 and a vertical distance of 2.
Every time we move one unit to the left from point J and two units up, we are dividing the line segment into five equal parts as shown in the picture.

The boundary of a park is shaped like a circle. The park has a rectangular playground in the center and 2 square flower beds, one on each side of the playground. The length of the playground is l and its width is w. The length of each side of the flower beds is a. Which two equivalent expressions represent the total fencing material required to surround the playground and flower beds? Assume that the playground and beds do not overlap.
The total fencing material required to surround the playground of length l and width w and 2 flower beds of side a is 2 ( l + b ) + 8a units.
What is perimeter of square or rectangle?The perimeter of a two-dimensional shape is the total length of the outline.
Perimeter of rectangle = 2 ( l + b ).
Perimeter of square = 4 × side.
Given the length of the playground is l and its width is w and the length of each side of the flower beds is a.
The total fencing material required = perimeter of playground + 2 * Perimeter of flower bed.
= 2 ( l + w ) + 2 * 4a
= 2 ( l + w ) + 8a units.
Therefore, The total fencing material required to surround the playground and flower beds is 2 ( l + w ) + 8a units.

f(x)=x^2. which of these is g(x)?
Answer:
According to the graph, g(x) is stretched by what seems to be 5, so g(x) is (x^2) / 25. (Square the stretching/compressing factor so 5^2 became 25). We also divide x^2 by this because it is being stretched. You multiply if it's being compressed.
You can check this by plugging 5 for x and trying to get 1.
g(x) = x^2 / 25
g(5) = 5^2 / 25 --> 25/25
g(5) = 1
g(x) = (x^2)/25
28.6% of city employees ride the bus to work. Last year, 29.7% of city employees rode the bus to work. What is the relative change from last year to this year?
(Express your answer rounded correctly to the nearest tenth of a percent!)
A percentage is a way to describe a part of a whole. The relative change from last year to this year is 3.7%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
28.6% of city employees ride the bus to work, therefore, the final value is 28.6. While Last year, 29.7% of city employees rode the bus to work, therefore, the initial value is 29.7.
Since relative change means change with respect to some value. Thus, the relative value with respect to last year is,
Relative value = (29.7-28.6)/29.7 = 0.037 = 3.7%
Hence, the relative change from last year to this year is 3.7%.

Because both lines have the same slope but different y-intercepts, we conclude that the lines are parallel.
What can we conclude about the two given lines?
Here we have the two lines:
6x - 2y = -2
y = 3x + 12
If we write both of these in the slope-intercept form, we get:
y = (-2 - 6x)/-2 = 3x + 1
y = 3x + 12
So, as you can see, both lines have the same slope but different y-intercepts. That means that the two lines are parallel, so they never do intercept.
