The functions (f.g)(x) and (g.s)(x) are illustrations of composite function
The values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10
How to determine the equation of the composite functionThe equation of the functions are given as:
f(x) = 3x - 8
g(x) = -2x + 5
s(x) = 4x^2 - 9x + 2
.
The composite functions are calculated using:
(fg)(x) = f(x) * g(x)
So, we have:
(f g)(x) = (3x - 8) * (-2x + 5)
Evaluate the product
(fg)(x) = -6x^2 + 15x + 16x - 40
Evaluate the like terms
(fg)(x) = -6x^2 + 31x - 40
Also, we have:
(gs)(x) = g(x) * s(x)
So, we have:
(gs)(x) = (-2x + 5) * (4x^2 - 9x + 2)
Expand
(gs)(x) = -8x^3 + 18x^2 -4x + 20x^2 - 45x + 10
Collect like terms
(gs)(x) = -8x^3 + 18x^2 + 20x^2-4x - 45x + 10
Evaluate the like terms
(gs)(x) = -8x^3 + 38x^2 -49x+ 10
Hence, the values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10

At the halftime show, a marching band in formation. the lead drummer started a point with coordinates (-2,-5) and move 3 steps up and 1 step right.
A. Write a rule to describe it the translation.
B. What were the coordinates of the drummer's final position?
Answers
Answer:
a) The answer is: (x + a, y + b)
b) The answer is: (-1, -2)
The initial coordinates are:
(x, y) = (-2, -5)
Let's find a and b.
a is a distance in x direction: a = 1
b is a distance in y direction: b = 3
The final position is:
(x + a, y + b) = (-2 + 1, -5 + 3) = (-1, -2)

your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (8 - 1) / (5 - (-5))
m = 7/10
y-intercept using slope above and anyone of given point. Let's use (-5, 1):
y = mx + b
1 = 7/10(-5) + b
1 = -35/10 + b
b = 45/10
b = 9/2
Equation of line:
y = mx + b
y = 7/10x + 9/2
Point slope form:
y - y₁ = m(x - x₁)

can anybody explain how to subtract mixed fractions?
Answers
Answer:
convert the mixed fractions to improper fractions (where the numerator is greater than or equal to the denominator): multiply the whole number part by the fraction's denominator, add that to the numerator, write the result on top of the denominator.if the denominators are not the same, work out the common denominator and rewrite the fractions with the same denominatorssubtract by subtracting the numerators and writing the result over the denominatorconvert back to mixed fractions by dividing the numerator by the denominator, write down the whole number answer, write down the remainder above the denominator.
Example
[tex]3\frac23-1\frac45[/tex]
convert to improper fractions:
[tex]\dfrac{3 \times 3+2}{3}-\dfrac{1 \times 5+4}{5}=\dfrac{11}{3}-\dfrac{9}{5}[/tex]
common denominator = 3 × 5 = 15, so:
[tex]\dfrac{11}{3}-\dfrac{9}{5}=\dfrac{11\times 5}{3\times 5}-\dfrac{9\times 3}{5\times 3}=\dfrac{55}{15}-\dfrac{27}{15}[/tex]
subtract:
[tex]\dfrac{55}{15}-\dfrac{27}{15}=\dfrac{55-27}{15}=\dfrac{28}{15}[/tex]
convert back to mixed fractions:
[tex]28 \div 15=1 \textsf{ remainder }13=1 \frac{13}{15}[/tex]
To subtract mixed fractions, we must follow the steps:
Convert the mixed fraction to improper fraction.2. Multiply the denominator and the numerator by the LCM of the denominators to make the denominators same. P.S: (If the denominators are the same, you can skip this step).
3. Simplify the fractions. (The denominators do not change).
4. (Optional) Convert the fractions to mixed fraction.
Solving an example:Let's take an example.
⇒ [tex]4 \frac{2}{5} - 3 \frac{3}{8}[/tex]Step-1: Convert the fractions to improper fraction:
⇒ [tex]4 \frac{2}{5} - 3 \frac{3}{8}[/tex]⇒ [tex]\frac{(4)(5) + 2}{5} - \frac{(3)(8) + 3}{8}[/tex]⇒ [tex]\frac{20 + 2}{5} - \frac{24+ 3}{8}[/tex]⇒ [tex]\frac{22}{5} - \frac{27}{8}[/tex]Step-2: Make the denominators same:
⇒ [tex]\frac{22}{5} - \frac{27}{8}[/tex]⇒ [tex]\frac{(22)(8)}{(5)(8)} - \frac{(27)(5)}{(8)(5)}[/tex]⇒ [tex]\frac{176}{40} - \frac{135}{40}[/tex]Step-3: Subtract:
⇒ [tex]\frac{176}{40} - \frac{135}{40}[/tex]⇒ [tex]\frac{41}{40}[/tex]Step-4: Convert the fraction to mixed fraction:
⇒ [tex]\frac{41}{40}[/tex]⇒ [tex]\frac{40}{40} + \frac{1}{40}[/tex]⇒ [tex]1 + \frac{1}{40}[/tex]⇒ [tex]1\frac{1}{40}[/tex]If f(x)=8x^3-6x^2+x-3 and g(x)=0, find (f o g)(x) and (g o f)(x)

This is a picture of a right angle, which is 90 degrees. We should first make an equation to represent this problem.
(x - 12) + 50 = 90
1. Subtract 50 from both sides of the equation.
(x - 12) = 40
2. Add 12 from both sides of the equation

I need to buy enough white boards for 172 students and there are 25 in a pack when the pack arrives 12 whiteboards are damaged. How many whiteboards are undamaged?
Answers
Answer:
There are 163 whiteboards undamaged.
Step-by-step explanation:
So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.
175 - 12 = 163.
There are 163 whiteboards undamaged.
