Answer: 16,250 units.
Step-by-step explanation:
This is a linear function which means that it takes the form of y = mx + c.
Y is the demand
X is the price
Find m.
= (Y₂ - Y₁) / (X₂ - X₁)
= (15,000 - 20,000) / (60 - 40)
= -250
Find c using substitution;
20,000 = -250 * 40 + c
20,000 = -10,000 + c
c = 20,000 + 10,000
c = 30,000
Linear function is;
y = -250x + 30,000
If selling price is $55;
y = -250 * 55 + 30,000
y = 16,250 units.
The demand is 17000 units when the selling price is $55 per unit
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let Q represent the demand and P represent the selling price.
20000 units for selling price of $40, hence (40, 20000). 16000 units for selling price of $60, hence (60, 16000).
Hence:
[tex]Q-Q_1=\frac{Q_2-Q_1}{P_2-P_1}(P-P_1)\\\\Q-20000=\frac{16000-20000}{60-40}(P-40)\\\\Q=-200P+28000[/tex]
For P = 55 unit:
W
Q = -200(55) + 28000 = 17000
The demand is 17000 units when the selling price is $55 per unit

El grafico de la ecuación lineal se puede ver en la imagen al final.
¿Como graficar la ecuación lineal?En este caso queremos graficar la ecuación lineal:
5y - 15 = -4x
Para ello debemos encontrar dos puntos en la linea, y para hacer eso podemos evaluar en dos valores de x.
Sí x = 0 obtenemos:
5y - 15 = -4*0
5y = 15
y = 15/5 = 3
Sí x= 5 obtenemos:
5y - 15 = -4*5
5y = -20 + 15
5y = -5
y = -5/-5 = -1
Entonces solo tenemos los dos puntos (0, 3) y (5, 1), ahora debemos graficar estos en un eje de coordenadas y trazar una linea que pase por ambos, como en el ejemplo de abajo.

k/3+16 algebraic expression
Answer: -48
Step-by-step explanation:
k/3 + 16
find the roots by factoring
which leads to -48
k/3 + 16
To add or subtract expressions, expand them so their denominators are the same. Multiply 16 by 3/3.
k/3 + 16 × 3/3
Since k/3 and 16 × 3/3 have the same denominator, we join their numerators to add them.
k + 16 × 3/3
We perform the multiplications in k+16×3.
k + 48/3

the equation is -5 = -8+v/3 help
Step-by-step explanation:
could it be that the equation is rather
-5 = (-8 + v)/3
?
that is a huge difference ...
to solve such an equation we keep transforming it (every change we make we have to do on both sides of the equation to keep the equality), until we have only the variable on one side, and everything else (which is then the solution) on the other side.
1st step : we get rid of the "/3" by multiplying both sides by 3.
that gives us
-5×3 = ((-8 + v)/3)×3 via the multiplication property.
2nd step : we simplify
-15 = -8 + v
3rd step : we get rid of the -8 on the side of the variable by adding 8 to both sides.
that gives us
-15 + 8 = -8 + 8 + v via the addition property.
4th step : we combine like terms (or simplify, if we can use it a second time) :
-7 = 0 + v
-7 = v
that's it.
If 1/2 cup of soup equals 120 milliliters, then how many milliliters are in 3 1/4 cups of soup?
If 1/2 cup of soup equals 120 milliliters, then there are 780 milliliters in
3 1/4 cups of soup.
A milliliter is a metric unit that is abbreviated as ml and is used to measure volumes for liquid and gas states. It is usually used to measure smaller volumes of liquids as it is equal to 1/1000 of a liter.
We can find the milliliters in 3 1/4 cups of soup as follows:
1/2 cup of soup = 120 milliliters
As 1/2 = 0.5
We can rewrite it as:
0.5 cup of soup = 120 milliliters
3 1/4 cups = 3.25 cups
Consider milliliters in 3 1/4 cups = x
Therefore,
0.5 cup = 120 ml
3.25 cups= x
Cross multiply to find x,
0.5 x = 120x3.25
0.5 x = 390
x= 390/0.5 = 780 milliliters
Hence it is found that 3 1/4 cups of soup is equal to 780 milliliters.

Yes, the moving boxes will fit in this volume.
What is volume ?The current volume of box :
Volume = height * width * depth
Volume = 12 * 9 * 2
Volume = 216 in³

Height and volume are the same
Width = 9 - 1 = 8
Depth = x
Volume = height * width * depth
216 = 12 * 8 * x
216 = 96x
x = 216 / 96

What is a geometric sequence?A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio. For instance, the geometric progression 2, 6, 18, 54, etc. has a common ratio of 3. Similar to that, the geometric series 10, 5, 2.5, 1.25,... has a common ratio of 1/2.
Powers [tex]r^{k}[/tex] of a given non-zero number r, like [tex]2^{k}[/tex] and [tex]3^{k}[/tex], are examples of a geometric sequence. A geometric sequence's basic structure is
[tex]ar,ar^{2},ar^{3}.ar^{4},-----[/tex]
where a is not equal to 0 is a scale factor that is equal to the initial value of the series and r is not equal to 0 is the common ratio.
A series is a sum, whereas a progression is a sequence. This is the difference between the two.
∑[tex]_{i=0}^{n}[/tex] [tex]ar^{i}=\frac{a(1+r^{n+1})}{1-r}[/tex]
We see that n= 99, r= -1/2, a=1
∑[tex]_{i=0}^{99}[/tex] [tex](\frac{-1}{2}) i=[/tex] [tex]\frac{1-(\frac{-1}{2})^{99+1} }{1-\frac{1}{2} }=\frac{1-(\frac{-1}{2})^{100} }{1+\frac{1}{2} }=\frac{1-\frac{1}{2}^{100} }{\frac{3}{2} }[/tex]

Blue whale is 15 times longer than otter.
To find how many times the blue whale is longer than the otter, we will perform division. We will divide the length of blue whale by length of otter, which we will give us the desired result.
Now, performing calculation as per the above statements -
Number of times longer length = [tex]\frac{3*10^{4} }{2*10^{3} }[/tex]
Performing division of numbers. Also, as we know, on division the exponents are subtracted. Hence, subtracting the exponents to get the desired result.
Number of times longer length = 1.5*[tex]10^{4-3}[/tex]
The result will be -
Number of times longer length = 1.5*10
Performing multiplication -
Number of times longer length = 15
Hence, we get that blue whale is 15 times longer than otter.

O-4x²-5x-9
Answer:
The first rectangle is 3x² - 6x + 13 more square feet then the second rectangle
Step-by-step explanation:
A rule for subtracting polynomials
Keep the first term the same Change the subtraction sign to addition Change the sign for every termSteps
Keep the polynomial 7x²- 4x + 12 the same Change the subtraction sign to addition Change the sign for every term 4x² + 2x - 1 becomes -4x² - 2x + 13At the end of the expression is (7x²- 4x + 12) + -4x² - 2x + 1
At this point you combine like terms like you do with adding polynomials so ( 7x² + (-4x²) is 3x², (-4x) + (-2x) is (-6x), and 12 + 1 is 13) so the final answer would be 3x²-6x+13
