which graph shows the solution to the system of linear equations?
y=-1/3x+1
y=-2x-3
y = -1/3x + 1
y = -2x - 3
We can compare the equations to the graphs and see which graph represents the intersection point of the two equations.
The first equation, y = -1/3x + 1, has a negative slope (-1/3) and a y-intercept of 1.
The second equation, y = -2x - 3, also has a negative slope (-2) and a y-intercept of -3.
Based on the slopes and y-intercepts, we can identify the correct graph by finding the point where the two lines intersect.
Unfortunately, since the graphs are not provided, I am unable to determine which specific graph shows the solution to the system of linear equations. I recommend referring to the graph representation of the equations and identifying the intersection point to determine the correct graph.

To solve the equation 2x - 1 - 7 = 9,
first
DO
write each side with base 2
add 7 to each side
divide both sides by 2
To solve the equation \(2^{x-1} - 7 = 9\), we add 7 to both sides make the bases the same, and equate the exponents.
What are some rules of exponents?Some common rules of exponents are
xᵃ×xᵇ = xᵃ⁺ᵇ.
xᵃ/xᵇ = xᵃ⁻ᵇ.
Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.
Given, An exponential expression
\(2^{x-1} - 7 = 9\).
\(2^{x -1} = 9 + 7.\)
\(2^{x-1} = 16.\)

Solve for y in the two equations below using substitution.
3x - 9y = 9
-2x - 2y = 8
Answer:
C
Step-by-step explanation:
3x - 9y = 9 → (1)
- 2x +2y = 8 ( subtract 2y from both sides )
- 2x = - 2y + 8 ( divide through by - 2 )
x = y - 4
substitute x = y - 4 into (1)
3(y - 4) - 9y = 9
3y - 12 - 9y = 9
- 6y - 12 = 9 ( add 12 to both sides )
- 6y = 21 ( divide both sides by - 6 )
y = \(\frac{21}{-6}\) = - \(\frac{7}{2}\)

when given two figures or their coordinates, how do you determine which is the preimage (the original) and which is the image (the transformed one)?
A preimage (the original) is the two-dimensional shape before any transformation. The image (the transferred one) is the figure after transformation.
A transformation is a process that manipulates a polygon or other two-dimensional object an a plane or coordinate system. Mathematical transformations describe how two-dimensional figures move around a plane or coordinate system.
Following are the types of transformations:-
Dilation, Reflection, Rotation, Shear, Translation.
Preimage is the set of all elements of the domain that are mapped into a given subset of the co-domain.
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.

a and b must be on opposite sides of zero (option D)
Explanation:
if a × b = c
and c is less than zero.
c can be less than zero if a < 0 and b > 0
c can be less than zero if b < 0 and a > 0
From the above, we can say a nd b must be on opposite sides this is because the left hand side of 0 shows > 0. While the right side of 0 shows > 0.
Hence, for a × b = c where c < 0,
a and b must be on opposite sides of zero (option D)

fourth step in the process of coding the responses to survey questions involves assigning a coded value to each response. Which of the following statements is true of this step? It follows the data entry phase of data preparation It is the step where omissions are either coded or left out. It is automated and is the easiest phase of the entire process. It is almost always necessary to avoid problems in the data entry phase. It precedes the data validation phase of data preparation.
The statement that is true of the fourth step in the process of coding the responses to survey questions is that it follows the data entry phase of data preparation.
In the first paragraph, we can summarize the answer as follows: The fourth step in the process of coding survey responses involves assigning a coded value to each response, and it follows the data entry phase of data preparation.
The process of coding survey responses involves converting the qualitative information obtained from the survey into a coded format that can be analyzed and interpreted. After the data entry phase, where the survey responses are typically entered into a database or software system, the fourth step begins. During this step, each response is assigned a specific code or value that represents its meaning or category. This coding process allows for easier analysis and statistical manipulation of the data.
The reason why this step follows the data entry phase is that the data entry phase focuses on accurately capturing the survey responses without any interpretation or coding. Once the responses are entered, the fourth step takes place to assign the appropriate codes. By separating the data entry and coding phases, it ensures that the responses are captured accurately before any coding or interpretation is applied.
While the statement suggests that this step is automated and the easiest phase of the entire process, this may not always be the case. The complexity and ease of this step can vary depending on factors such as the nature of the survey questions, the coding system being used, and the clarity of the response options. Additionally, the statement that it is almost always necessary to avoid problems in the data entry phase is not accurate. The coding step is not directly related to avoiding problems in the data entry phase but rather focuses on transforming the data for subsequent analysis. Furthermore, the statement does not mention anything about omissions; therefore, it is not directly related to the process of coding the responses. Lastly, the statement correctly states that this step precedes the data validation phase, which typically involves checking the accuracy and consistency of the coded data.

How do you calculate F G and G of f?
You will be calculate the function F(G) = f(g(x)) and G(F) = g(f(x)).
What is function ?
A function is a kind of rule that, for one input, it gives you one output. Image source: by Alex Federspiel. An example of this would be y=x2. If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.
Have given ,
Two functions , f(x) and g(x)
The composition of two functions g and f is the new function we get by performing f first, and then performing g. For example, if we let f be the function given by f(x) = x2 and let g be the function given by g(x) = x + 3, then the composition of g with f is called gf and is worked out as gf(x) = g(f(x)) .
So , You will be calculate the function F(G) = f(g(x)) and G(F) = g(f(x)).

The function f(x)=x−−√ is reflected over the x-axis, translated 4 units down and 5 units to the left, then vertically stretched by a factor of 3. Which equation best represents the new function created?
Answer:
U dry aint put a answer
Step-by-step explanation:
Transformation involves changing the position of a function.
The equation of the new function is: \(\mathbf{g(x) = -3\sqrt{x + 5} - 12}\)
The function is given as:
\(\mathbf{f(x) = \sqrt x}\)
The rule of reflection across the x-axis is:
\(\mathbf{(x,y) \to (x,-y)}\)
So, we have:
\(\mathbf{f'(x) = -\sqrt x}\)
The rule of translation, 4 units down and 5 units left is:
\(\mathbf{(x,y) \to ( x + 5,y-4)}\)
So, we have:
\(\mathbf{f"(x) = -\sqrt{x + 5} - 4}\)
The rule of vertical stretch by a factor of # is:
\(\mathbf{(x,y) \to (x,3y)}\)
So, we have:
\(\mathbf{g(x) = 3(-\sqrt{x + 5} - 4)}\)
\(\mathbf{g(x) = -3\sqrt{x + 5} - 12}\)
Hence, the equation of the new function is:
\(\mathbf{g(x) = -3\sqrt{x + 5} - 12}\)

What’s the slope of this graph??
The slope of the line passing through the points (0, 30) and (8, 18) is -1.5.
Given is a graph of a line passing through the points (0, 30) and (8, 18).
To find the slope of the line passing through two points, you can use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's use the points (0, 30) and (8, 18) to calculate the slope:
x1 = 0
y1 = 30
x2 = 8
y2 = 18
slope = (18 - 30) / (8 - 0)
= -12 / 8
= -1.5
Therefore, the slope of the line passing through the points (0, 30) and (8, 18) is -1.5.
