F(x)⋅g(x)
The composite function f(x). g(x) is represented as 3x² - 17x + 10
How to find composite function?The composite function can be solved as follows:
f(x) = 3x - 2
g(x) = x - 5
Therefore, the composite function f(x). g(x) is as follows:
f(x). g(x) = f(x) × g(x)
Hence,
f(x) × g(x) = (3x - 2)(x - 5)
f(x) × g(x) = 3x² - 15x - 2x + 10
f(x) × g(x) = 3x² - 17x + 10

In a sale, normal prices are reduced by 10%.
David bought a pair of trainers in the sale for £36.
What was the original price of the trainers?
In a sale, if the normal prices are reduced by 10% and David bought a pair of trainers in the sale for £36 then the marked price of these trainers was £40.
What is original price?Original price is said to be as the price that was fixed by the MSRP (i.e said to be the Manufacturer’s Suggested Retail Price).
In most of the case scenario, the original price would taken to be as always lower than the current price and then also in some other cases, original price and current price can be taken as the same.
How do you calculate the original price?First you have to convert the total percent discount to a decimal by dividing by 100% . Step 2: Set up the equation P=(1−d)x P = ( 1 – d ) x to find the original price of the item where P is the sale price, d is the discount as a decimal, and x is the original price of the item.
The selling price, may be that of a product or a service, is said to be as the customer or client’s final price
How do you find the original price from a discounted price calculator?To calculate the exact original price of a selected item, you have to divide the sale price by the value of 1 minus the entire value of the percentage off and then divided by 100.

Driver A and B have two different routes. Driver A's route is 80km, and driver B's route is 100km. Driver B travels 10km/h faster than driver A and finishes 10 minutes earlier. What are the speeds of each driver?
Speed of Driver A is 30 km/h.
Speed of Driver B is 40 km/h
Define speed.The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.
Given Data
Driver A and B have two different routes. Driver A's route is 80km, and driver B's route is 100km. Driver B travels 10km/h faster than driver A and finishes 10 minutes earlier.
Distance = Speed (Time)
Distance for Driver A: 80 kilometers
Consider Driver A's speed to be A km/h.
Driver A's time was [tex]\frac{80}{A}[/tex] hours.
Distance for Driver B is 100 kilometers
Speed of Driver B: A + 10 km/h
Driver B's time was equal to 100/(A + 10) hours.
Arrived 10 minutes early, or [tex]\frac{10}{60}[/tex], or [tex]\frac{1}{6}[/tex]hour.
100/(A + 10) = [tex]\frac{80}{A}[/tex] - [tex]\frac{1}{6}[/tex]
600A = 480(A + 10) - A(A + 10)
600A = 480A + 4800 - A² - 10A
A² +130A - 4800 = 0
A² + 160A - 30A - 4800 = 0
A(A + 160) - 30(A + 160) = 0
(A - 30)(A + 160) = 0
A = 30 since speed cannot be negative.
Speed of Driver A is 30 km/h.
Speed of Driver B: 40 km/h

Answer: The answer for X' is -1,8, and the answer for X'' is 3,14
Step-by-step explanation:
When talking about reflections across the x-axis, the formula would be: (x,y)---> (x, -y) so you first start out with -1, -8 then translate it to -1,8, because you swap the y. Then you add 4 to -1 because you move 4 to the right which gives you 3, and then you add 6 to 8 because you move up 6, which gives you 14, so your final answer is 3,14

3.2 x 10⁶
Explanation:
Given the quotient:
[tex]\frac{1.232\times10^8}{3.85\times10}[/tex]We can rewrite the expression by removing the decimals as follows:
[tex]=\frac{1232\times10^{-3}\times10^8}{385\times10^{-2}\times10}[/tex]Next, we rewrite the powers of 10 so we can cancel out common terms.
[tex]\begin{gathered} =\frac{1232}{385}\times\frac{(10^{-2}\times10^{-1})\times(10\times10^7)}{10^{-2}\times10} \\ \frac{1232}{385}\times10^{-1}\times10^7 \end{gathered}[/tex]Next, express the first fraction in the lowest possible form:
[tex]\begin{gathered} =\frac{16\times77}{5\times77}\times10^{-1}\times10^7 \\ =\frac{16}{5}\times10^{-1}\times10^7 \\ =3.2\times10^{-1+7} \\ =3.2\times10^6 \end{gathered}[/tex]The quotient expressed in scientific notation is 3.2 x 10⁶.

What is the graph of 5y- 15x =30
A graph of this linear function (y = 3x + 6) is shown in the image attached below.
What is a graph?A graph can be defined as a type of chart that is commonly used for the graphical representation of data on both the horizontal line (x-axis) and vertical line (y-axis) of a cartesian coordinate.
Next, we would simplify the given linear function by dividing all through by 5 as follows:
5y - 15x = 30
5y/5 - 15x/5 = 30/5
y - 3x = 6
Rearranging the linear function, we have:
y = 3x + 6
In this context, we can reasonably and logically deduce that only the graph of a proportional relationship such as a linear function is always characterized by a straight line with all of the data points passing through the origin (0, 0).
In conclusion, a graph which represents the given linear function does not show a proportional relationship between the value of x and y.
