When we evaluate the quotient functions, (mn)(x) for x = -3
(mn)(-3) = 9 and (m/n) (x), x ≠ 0
How did we evaluate the quotient function?To evaluate the quotient function (mn)(x) for x = -3, we substituting x = -3 into the function mn(x).
This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.
We then need to evaluate (m/n)(x), x ≠ 0.
This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

WHY must the same operation be performed on both sides of an equation?
Answers
Answer:When you are given a problem, the two sides are equal, so they are equally weighted. As long as you do the same thing on both sides, they remain the same weight. The only way that one side can become "more weight" on a side is if you make a math mistake, and thus the answer would not satisfy the original equation

Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]
Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).
[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]
Distribute:
[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]
Simplify:
[tex]2x-4x=x+24[/tex]
Combine like terms:
[tex]-2x=x+24[/tex]
Subtract [tex]x[/tex] from both sides of the equation:
[tex]-3x=24[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:
[tex]x=-\frac{24}{3}[/tex]

If the length of a rectangle in terms of x is x2 + 2x + 5, and its width is 2x + 3, what is the perimeter of this rectangle?
Answers
Answer:
6x
Step-by-step explanation:
Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].
What is perimeter of rectangle?The perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides.
Given
Length of a rectangle in terms of x = [tex]x^{2} +2x+5[/tex]
Width of a rectangle in terms of x = [tex]2x+3[/tex]
Perimeter of rectangle = 2(length + width)
P = [tex]2(x^{2} +2x+5 + 2x+3)[/tex]
P = [tex]2(x^{2} +4x+8)[/tex]
P = [tex]2(x^{2} )+2(4x)+2(8)[/tex]
P = [tex]2x^{2} +8x+16[/tex]
Hence, Perimeter of rectangle is [tex]2x^{2} +8x+16[/tex].

Naomi is buying bagels for a family gathering. Each bagel costs $1.25. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
Answers
Answer:
total cost = 1.50x
Step-by-step explanation:
Given cost of 1 bagel = $1.25
Let the number of bagels purchased by x
cost of x bagels = cost of 1 bagel *x
cost of x bagels = 1.50*x
Thus,
relationship between bagels and total cost is as shown below
total cost = 1.50x
where x is the number of bagels purchased.
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is N(x) = 1.25x.
So N(4) =5, meaning 4 bagels will cost 5 dollars.

g. If you are going 70.0 mi/hr, how many miles do you travel in 0.681 hours!
Answers
Answer:
47.67 miles (in 40.86 minutes or 40 minutes and 51.6 seconds)
Step-by-step explanation:
Simple. Multiply these values together to cancel out the quantity in the denominator (cross multiply).
0.681 * 70 = 47.67
let x be the distance in miles:
70.0/1 = x/0.681
0.681 * 70 = 1 * x
47.67 = 1 * x
47.67 = x

formula to find mindpoint is
[tex](\frac{x2 + x1}{2} \frac{y2 + y1}{2} )[/tex]
(0,9) = (x1, y1)
(4,5) = (x2,y2)
now substitute those into the formula!
[tex](\frac{4 + 0 }{2} \frac{5 + 9}{2} )[/tex]
now solve for x & y !!
[tex]x = \frac{4 + 0}{2} = \frac{4}{2 } = 2[/tex]
[tex]y = \frac{5 + 9}{2} = \frac{14}{2} = 7[/tex]

Ecuación 2:
10x + 20y = 8000
ayudaaa
Answers
Answer:
y = 300
x = 200
Step-by-step explanation:
Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:
x + y = 500
10*x + 20*y = 8000
Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.
El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:
x = 500 - y.
Ahora podemos reemplazar eso en la segunda ecuación y obtener:
10*(500 - y) + 20*y = 8000.
Ahora resolvemos esto para y.
5000 - 10*y + 20*y = 8000
10*y = 8000 - 5000 = 3000
y = 3000/10 = 300.
Y sabíamos que:
x = 500 - y = 500 - 300 = 200
Entonces la solución es:
y = 300
x = 200

What is the perimeter of this triangle ?
Answers
Answer:
36 units
Step-by-step explanation:
The two legs of this right triangle are 9 and 12. In order to find the length of the hypotenuse, you must plug in the 9 and 12 to the Pythagorean theorem:
a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse
If you plug in the values 9 and 12, you get:
9^2 + 12^2 = c^2
= 81 + 144 = c^2
= 225 = c^2
= 15 = c
This means that the hypotenuse is 15 units long. Now, you just need to add all the sides to get:
9 + 12 + 15
= 36 units
(Also as a fun fact, a Pythagorean Triple is when the three sides of a right triangle are integers. It is good to memorize a few of these, like 3-4-5, 5-12-13, 7-24-25 and 8-15-17. The largest side value is always the hypotenuse, and if you multiply all the sides by a scale factor, you can get other triples. If you knew the 3-4-5 triple, you might have noticed that 9 and 12 are 3 times each of the legs 3 and 4. From that information, you could just multiply the 5 by 3 to get 15 for the hypotenuse of this triangle, which might've made this problem a little easier)
