Answer: (-5, -5)
Step-by-step explanation: Reflection is a transformation in which there is a flip of the figure, object or point.
In our case, the point is reflected over the x-axis. When this happens, the y-coordinate of the point "flips", turning negative. So, thepoint reflected over the x-axis is (-5, -3).
Translation is also a transformation. In this transformation, the object figure or point moves a fixed distance, without changing the shape. When it is translated horizontally, the x-coordinate changes: if it is to the right, we add units; if it is to the left, we subtract units.
When the translation is vertical, the y-coordinate changes: if it is up, add units; If it's down, subtract units.
After the reflection, the now point (-5, -3) is translated down 2 units. Then, the change will be:
(-5, -3) = (-5, -3-2) = (-5, -5)
The final coordinates for the point, after reflection and translation, is (-5,-5).

Solve the system of linear equations by substitution. 2x=y−10 x+7=y
Answer:
(-3, 4)
Step-by-step explanation:
2x = y - 10 (y = x +7) so
2x = x +7 - 10
2x = x -3
x = -3
-3 + 7 = y
4 = y
Step-by-step explanation:
2x = y - 10 and x + 7 = y.
By Substitution,
2x = (x + 7) - 10.
=> 2x = x - 3, x = -3.
Therefore y = (-3) + 7 = 4.
The pair of solutions are x = -3, y = 4.
What is the standard form of 2x2x2x2x2?
Answer:
The standard enthalpy of formation is the energy that would be involved if one mole of the substance were to be formed from its elements that were at standard conditions of temperature and pressure which are 25 degrees C and one atm pressure.
Step-by-step explanation:
The standard form of the given expression 2 × 2 × 2 × 2 × 2 is 2⁵.
The expression is given as follows:
2 × 2 × 2 × 2 × 2
When simplifying repeated multiplication of the same number, we use exponents as a concise representation.
The exponent denotes how many times the base is multiplied by itself. In this case, 2 is multiplied five times (2 × 2 × 2 × 2 × 2).
So, it is equal to 2⁵.
In this form, the base (2) is raised to the power of the number of times it is multiplied (5).
Thus, the standard form of 2 × 2 × 2 × 2 × 2 is 2⁵.

Can someone help me please in thank you
Answer:
Hint: f(x) = y
Step-by-step explanation:
The best way to approach these type of questions is to first substitute the x in the equation with one of the numbers from the table that contains x and y. For example, number 5, f(x) = 8x - 5. One of the numbers states x as 0, meaning I can substitute 0 into the equation as x => f(x) = 8(0) - 5. After that I solve to find f(x), and fill out the slot next to 0. This can be repeated for all blank slots of y. Hope it helped. :)

Are 2(x + 1) and 2x + 1 equivalent expressions? explain.
I’m not in a hurry, take your time.
Answer:
Yes
Step-by-step explanation:
When you simplify 2(x+1). [MULTIPLY]
It comes 2x+1 so it is equivalent to 2x+1
Yes, 2(x + 1) and 2x + 1 are equivalent algebraic expression.
Given that,
To determine whether the 2(x + 1) and 2x + 1 are equivalent expressions.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let
y = 2 (x + 1) - - - - - -(1)
z = (2x + 1) - - - - - (2)
from equation1
y = 2 (x + 1)
using the PEMDAS rule, applying operation on the parenthesis 1st as distributive property,
now,
y = 2x + 1
Since the outcome of the equation is equal to equation 2.
Thus, 2(x + 1) and 2x + 1 are equivalent algebraic expression.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 9 inches. The height of the cone is 18 inches.
Use pi = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.
Answer:
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).
Step-by-step explanation:
Diameter of cylinder = 8 inches
Diameter of cone = 8 inches
Height of cylinder = 9 inches
Height of cone = 18 inches
We need to find the relationship between the volume of this cylinder and this cone.
First we will find volume of the cylinder
The formula used is: [tex]Volume=\pi r^2h[/tex]
We have
Diameter of cylinder = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cylinder = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2h\\Volume=3.14\times (4)^2 \times 9\\Volume=452.16[/tex]
So, Volume of cylinder = 452.16 inches³
Now, we will find volume of the cone
The formula used is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
We have
Diameter of cone = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cone = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14 \times (4)^2 \times \frac{18}{3}\\Volume=3.14 \times (4)^2 \times 6\\Volume=301.44[/tex]
So, Volume of cone = 301.44 inches³
Now, comparing volume of both cylinder and cone.
Volume of cylinder = 452.16 inches³
Volume of cone = 301.44 inches³
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).

One equation in a system of equations is y=4x-5 write a second equation to complete the system if the solution to the system is (3,7) PLSSS BE QUICK :))
Answer:
4y = -x + 31
Step-by-step explanation:
Given that one equation in a system of equations is y = 4x - 5 write a second equation to complete the system if the solution to the system is (3,7)
Since the solution of the system is (3, 7), that means the two lines of equations meet or intersect at point X = 3 and Y = 7
Let assume that the two equations are perpendicular to each other. Then, there slope can be expressed as
M1M2 = -1
Where M1 = 4
Find M2
4M2 = -1
M2 = -1 / 4
Using general linear equation
Y = MX + C
Let's find C by substituting Y, X and M2
7 = -1 /4( 3 ) + C
7 = -3/4 + C
C = 7 + 3/4
C = 31/4
Substitute C back into the equation
Y = -1/4X + 31/4
4y = -x + 31
Therefore, the second equation is
4y = -x + 31

which is the graph of f(x) = 3 square root x/4
Answer:
Given function
[tex]f(x)=\dfrac{3}{4}\sqrt{x}[/tex]
Parent function
[tex]f(x)=\sqrt{x}[/tex]
The square root of a negative number cannot be taken, therefore the domain and range of the parent function are restricted:
Domain: [0, ∞)Range: [0, ∞)This means the parent function begins at the origin (0, 0) and is restricted to Quadrant I.
The only transformation the parent function has undergone is it has been multiplied by 3/4, which means it has been stretched vertically by a factor of 3/4. Therefore, the domain and range will not change.
The points shown on the given graphs are all where x = 4.
[tex]\textsf{Graphed function}: \quad f(4)=\dfrac{3}{4}\sqrt{4}=1.5 \implies (4,1.5)[/tex]

The population of a city is modeled by the exponential function ƒ (x) = 689,254 · 2.40.014x, where x is the number of years after 2000. In what year will the city's population exceed one million?
Answer:
2036Step-by-step explanation:
Given the population of a city is modeled by the exponential function
ƒ (x) = 689,254 · 2.4e^0.014x, where x is the number of years after 2000
In order to determine the year that the city's population will exceed one million, we will substitute f(x) = 1,000,000 and find x first as shown:
1,000,000 = 689,254 2.4e^0.014x,
1000000/689,254 = 2.4e^0.014x,
1.4508 = 2.4e^0.014x,
1.4508 /2.4 = e^0.014x,
0.6045 = e^0.014x,
Apply ln to both sides
ln 0.6045 = lne^0.014x,
-0.5033 = 0.014x
x = -35.95
Since x cannot be negative, lets say x ≈ 36years
This means that the population will exceed one million after about 36 years. The year it will exceed this amount will be 2000+36 = 2036
Note that the exponential equation used was not correctly written but the same calculation can be employed for any exponential functions you might have.
