Answer:
The first transformation occurs when we add a constant d to the parent function \displaystyle f\left(x\right)={b}^{x}f(x)=b
x
, giving us a vertical shift d units in the same direction as the sign. For example, if we begin by graphing a parent function, \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
, we can then graph two vertical shifts alongside it, using \displaystyle d=3d=3: the upward shift, \displaystyle g\left(x\right)={2}^{x}+3g(x)=2
x
+3 and the downward shift, \displaystyle h\left(x\right)={2}^{x}-3h(x)=2
x
−3. Both vertical shifts are shown in Figure 5.
Graph of three functions, g(x) = 2^x+3 in blue with an asymptote at y=3, f(x) = 2^x in orange with an asymptote at y=0, and h(x)=2^x-3 with an asymptote at y=-3. Note that each functions’ transformations are described in the text.
Figure 5
Observe the results of shifting \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
vertically:
The domain, \displaystyle \left(-\infty ,\infty \right)(−∞,∞) remains unchanged.
When the function is shifted up 3 units to \displaystyle g\left(x\right)={2}^{x}+3g(x)=2
x
+3:
The y-intercept shifts up 3 units to \displaystyle \left(0,4\right)(0,4).
The asymptote shifts up 3 units to \displaystyle y=3y=3.
The range becomes \displaystyle \left(3,\infty \right)(3,∞).
When the function is shifted down 3 units to \displaystyle h\left(x\right)={2}^{x}-3h(x)=2
x
−3:
The y-intercept shifts down 3 units to \displaystyle \left(0,-2\right)(0,−2).
The asymptote also shifts down 3 units to \displaystyle y=-3y=−3.
The range becomes \displaystyle \left(-3,\infty \right)(−3,∞).
Graphing a Horizontal Shift
The next transformation occurs when we add a constant c to the input of the parent function \displaystyle f\left(x\right)={b}^{x}f(x)=b
x
, giving us a horizontal shift c units in the opposite direction of the sign. For example, if we begin by graphing the parent function \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
, we can then graph two horizontal shifts alongside it, using \displaystyle c=3c=3: the shift left, \displaystyle g\left(x\right)={2}^{x+3}g(x)=2
x+3
, and the shift right, \displaystyle h\left(x\right)={2}^{x - 3}h(x)=2
x−3
. Both horizontal shifts are shown in Figure 6.
Graph of three functions, g(x) = 2^(x+3) in blue, f(x) = 2^x in orange, and h(x)=2^(x-3). Each functions’ asymptotes are at y=0Note that each functions’ transformations are described in the text.
Figure 6
Observe the results of shifting \displaystyle f\left(x\right)={2}^{x}f(x)=2
x
horizontally:
The domain, \displaystyle \left(-\infty ,\infty \right)(−∞,∞), remains unchanged.
The asymptote, \displaystyle y=0y=0, remains unchanged.
The y-intercept shifts such that:
When the function is shifted left 3 units to \displaystyle g\left(x\right)={2}^{x+3}g(x)=2
x+3
, the y-intercept becomes \displaystyle \left(0,8\right)(0,8). This is because \displaystyle {2}^{x+3}=\left(8\right){2}^{x}2
x+3
=(8)2
x
, so the initial value of the function is 8.
When the function is shifted right 3 units to \displaystyle h\left(x\right)={2}^{x - 3}h(x)=2
x−3
, the y-intercept becomes \displaystyle \left(0,\frac{1}{8}\right)(0,
8
1
). Again, see that \displaystyle {2}^{x - 3}=\left(\frac{1}{8}\right){2}^{x}2
x−3
=(

x
, so the initial value of the function is \displaystyle \frac{1}{8}

A slope of -4 through the point (5,-1) anyone know this?
Answer:
y = -4x + 19
Step-by-step explanation:
We will use the linear equation y = mx + c for this
m is our slope and c is our offset (y-intercept)
We are informed that our slope is -4 so
y = -4x + c
To find the equation of a line passing through the point (5,-1) we simply plug in our values into our equation
-1 = -4(5) + c
Then we can find c
-1 = -20 + c
19 = c
Now that we have our m and c, we can form an equation of a line that passes through our point:
y = -4x + 19

supplement is
Check
Next
Answer:
The angle is 90, my friend gave the answer as 10, so he is incorrect
The complement of the angle is not 10 but 0
The measure of the supplement is 90 degrees
Step-by-step explanation:
The complement of an angle is simply the value of 90 minus the angle
The supplement of an angle is simply the value of 180 minus the angle
So let’s say the angle we are looking at is x
The complement of the angle will be 90 - x
The supplement of the angle will be 180-x
so from the question;
x = 90-x + 180-x
x = 270 - 2x
2x + x = 270
3x = 270
x = 270/3
x = 90
The measure of the angle is 90 degrees
the measure of the complement of this angle is 90-90 = 0 degrees
The measure of the complement is 180-90 = 90 degrees

You are considering a certain telephone company. They charge $0.19 per minute of talking, plus a fixed base monthly fee of $70. If M represents the number of minutes you talk in a month, and C is the total monthly charge, which of these is the correct relationship between M and C?
Answer:
.19m+70=c
Step-by-step explanation:
.19m represents $0.19 per minute
+70 represents the fixed monthly fee
so you'd multiply the minutes by 19cents and add the $70 to find cost per month

C) Interpretamos la oración paso a paso conforme al lenguaje matemático conocido:
(i) Si una pista de baile tiene un área de 5625 m²:
[tex]A = 5625\,m^{2}[/tex]
(ii) Si una pista de baile tiene un área de 5625 m² y se sabe que su ancho mide lo mismo que su ancho:
Lo que se infiere de la afirmación es que la pista de baile sería un cuadrilátero y más precisamente, un cuadrado:
[tex]A = 5625\,m^{2}[/tex]
[tex]A = w\cdot l[/tex] ([tex]l[/tex] - Largo, [tex]w[/tex] - Ancho)
[tex]w = l[/tex]
Entonces la ecuación algebraica sería:
[tex]l^{2} = 5625\,m^{2}[/tex]
(iii) Si una pista de baile tiene un área de 5625 m² y se sabe que su ancho mide lo mismo que su ancho, cuanto medirán las dimensiones de la pista de baile:
Lo que se infiere de la afirmación es que la pista de baile sería un cuadrilátero y más precisamente, un cuadrado:
[tex]A = 5625\,m^{2}[/tex]
[tex]A = w\cdot l[/tex] ([tex]l[/tex] - Largo, [tex]w[/tex] - Ancho)
[tex]w = l[/tex]
Entonces la ecuación algebraica sería:
[tex]l^{2} = 5625\,m^{2}[/tex]
Y obtenemos la longitud por despeje:
[tex]l = \sqrt{5625\,m^{2}}[/tex]
[tex]l = 75\,m[/tex]
[tex]w = 75\,m[/tex]
Ese problema se traduce bajo esta forma lógica como [tex]w\cdot l = 5625\,m^{2}[/tex] [tex]\land[/tex] [tex]w = l[/tex] [tex]\implies[/tex] [tex]w = 75\,m[/tex] [tex]\land[/tex] [tex]l = 75\,m[/tex].

Answer:
if you need to find the value of x then I can help
First the equation looks like this:
2x + 3 = -7
first find the value of "x" which will be -5 then the equation will look like this:
2(-5) then multiply 2 and -5 which is equal to -10
this will make the equation look like this:
-10 + 3 = -7
then evaluate
-10 + 3 = -7
-7 = -7
Therefore the value of "x" is -5

A piece of machinery depreciates $8000 the first year,
$7500 the second year, and $7000 the third year. If the
rate of depreciation is constant, what is the amount of
depreciation of the piece of machinery in the sixth year?
Answer:
6,500 = 4th year
6,000 = 5th year
5,500 = 6th year.
The amount of depreciation of the piece of machinery in the sixth year is $5000.
What is depreciation?A reduction in the value of an asset over time, due in particular to wear and tear.
Given that, a piece of machinery depreciates $8000 the first year, $7500 the second year, and $7000 the third year
The rate of depreciation is $500 per year
For 6 years the reduction is = 6*500 = $3000
Therefore, after 6 years = $8000 - $3000 = $5000
Hence, The amount of depreciation of the piece of machinery in the sixth year is $5000

A stage designer paid $4 per square foot for flooring to be used in a square room. If the designer spent $600 on the flooring, about how long is a side of the room? Round to the nearest foot.
• How is the area of a square related to its side length? Explain
• How can you estimate the length of a side of a square? Explain
Answer:
A square has equal width and length. To find the area, you have to multiply the width by length but because they are the same length, you may some time see the formula written as L*L or [tex]L^{2}[/tex].
The area of used up by the squares is 150sq feet. I found this by dividing 600 by 4. You can find an estimate by equating 150 the L*L. This gives you an approximate value of 12.

the length of the rectrangular field is twice its breadth ifvthe are of the field is 3200 square meters what is the cost of fencing the field at rs 40 per meter
Answer:
Step-by-step explanation:
Area of a rectangle = Length x Breadth.
Area= L x B
We are told the length is twice the breadth.
You can write this as :
Length = 2 x Breadth
L = 2B
If you put that into the area formula at the beginning, we get:
Area = L x B
Area = 2B x B = [tex]2B^2[/tex]
They also told us that the area of the field is 3200 square meters. So,
Area = [tex]2B^2[/tex] = 3200
Divide both sides by 2
[tex]B^2[/tex]= [tex]\frac{3200}{2} = 1600[/tex]
Now to solve for B we need to square root both sides.
[tex]B = \sqrt{1600}[/tex] = 40
So now we know the Breadth is 40meters
Remember earlier we said Length = 2 x Breadth
[tex]L = 80[/tex]
Cost of fencing the field = 2L + 2B
Cost of fencing the field = 2 x 80 + 2 x 40 = $240
