Step-by-step explanation:
A graphic designer charges an hourly rate. In July, the only expense is for advertising. The function graphed models the designer's net income, y, for July for x hours of work.
Select True or False to describe each statement.
The x-intercept represents the amount the designer charges for 1 h of work.
The difference between 0 and the y-intercept represents the amount the designer spent on advertising.
The slope represents the designer's hourly rate.
Answers
The x-intercept is the value of x when y is zero, thus from the graph, the x-intercept represents the number of hours he has to work to cover for his expenses.
Therefore, the statement "The x-intercept represents the amount the designer charges for 1 h of work." is false.
The y-intercept is the value of y when x is 0, from the graph the y intercept represent the net income when he has not done any work, i.e. the y-intercept represent his expenses.
Therefore, the statement "The difference between 0 and the y-intercept represents the amount the designer spent on advertising." is true.
The slope of a straight line is given by the change in y divided by the corresponding change in x. From the graph, given that the y-axis represent the net income in dollars and the x-axis represent the time worked in hours. Change in y divided by change in x is given by dollars per hour which represent his hourly charge.
Therefore, the statement "The slope represents the designer's hourly rate." is true.

Which expressions are equivalent to ? Check all that apply.
Answers
To determine if expressions are equivalent, we simplify them or substitute variables with actual values to see if they yield the same result. We simplify by eliminating terms where possible, grouping like terms, and applying mathematical operations.
Explanation:Without the original mathematical expressions, it's difficult to provide direct answers to your question. Normally, we determine whether expressions are equivalent by simplifying them using algebraic rules or substituting variable with actual values to see if they produce the same results.
For example, the expressions 2(3 + 5) and 6 + 10 are equivalent because they both simplify to 16. We identify equivalent expressions by simplifying which includes eliminating terms where possible, grouping like terms, and applying mathematical operations.
Ultimately, the exact process may vary depending on the complexity and specific form of the expressions in question.

Which formula gives the coordinates of the midpoint of the segment connecting points (a,
b.and (c, d)?
Answers
(a,b)...x1 = a and y1 = b
(c,d)...x2 = c and y2 = d
so ur formula would be :
m = (a + c)/2 , (b + d)/2 <==
Answer:
Formula that gives coordinates of the mid point of the segment connecting is [tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]
Step-by-step explanation:
Given point are ( a , b ) and ( c , d )
To find : Coordinates of the mid point of the segment connecting given points.
We know that if point are [tex](x_1,y_1)\:\:and\:\:(x_2,y_2)[/tex]
then coordinate of the midpoints given by [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
So, Coordinates of the given points = [tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]
Therefore, Formula that gives coordinates of the mid point of the segment connecting is [tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]
A 20.0 kg sled is being pulled across a horizontal surface at constant velocity. The pulling force has a magnitude of 80.0N and is directed at an angle of 30.0º above the horizontal. Determine the coefficient of kinetic friction.
Answers
The coefficient of kinetic friction is 0.58
To determine the coefficient of kinetic friction [tex](\(\mu_k\))[/tex], we can use the following approach:
1. Identify the horizontal component of the pulling force [tex](\(F_{\text{pull, horizontal}}\))[/tex] and set it equal to the force of kinetic friction [tex](\(f_k\))[/tex].
2. The equation for the horizontal component of the pulling force is:
[tex]\[ F_{\text{pull, horizontal}} = F_{\text{pull}} \cdot \cos(30^\circ) \][/tex]
3. The equation for the force of kinetic friction is:
[tex]\[ f_k = \mu_k \cdot N \][/tex]
4. Since the sled is on a horizontal surface, the normal force [tex](\(N\))[/tex] is equal to the weight of the sled [tex](\(m \cdot g\))[/tex], where m is the mass of the sled and g is the acceleration due to gravity.
Putting these equations together and setting them equal to each other because the sled is moving at constant velocity, we get:
[tex]\[ F_{\text{pull}} \cdot \cos(30^\circ) = \mu_k \cdot m \cdot g \][/tex]
Now, substitute the given values:
[tex]\[ 80 \cdot \cos(30^\circ) = \mu_k \cdot 20 \cdot 9.8 \][/tex]
Solve for [tex]\(\mu_k\)[/tex]:
[tex]\[ \mu_k = \frac{80 \cdot \cos(30^\circ)}{20 \cdot 9.8} \][/tex]
Calculating this expression yields:
[tex]\[ \mu_k \approx 0.58 \][/tex]
So, the calculated coefficient of kinetic friction is approximately 0.58, which matches the provided answer.
Complete question:
A 20 kg sled is being pulled across a horizontal force at a constant velocity the pulling force has a magnitude of 80 N and it's directed at an angle of 30° above the horizontal determine the coefficient of kinetic friction.

Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.
Answers
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

The problem asks to solve a system of two equations by representing each condition as an equation. By simplifying and substituting, we can find the values of the two unknowns.
Explanation:The question involves solving a system of two equations. Let's denote the first number as x and the second number as y. The given conditions can be represented as follows:
x + y = 2x - 18x - y = 2y - 32To simplify, we can rewrite the equations as:
y = x - 18x = 2y + 32We can substitute equation (1) into equation (2) to get:
x = 2(x - 18) + 32
Solving the equation will give us the value of x and substituting x into equation (1), we will get the value of y.

Two benefits of following the 4 step method of problem solving
Answers
Following the 4-step method of problem-solving offers the benefits of structured decision-making and enhanced clarity in identifying and addressing core issues. These advantages significantly contribute to effective decision-making and successful implementation of solutions.
Explanation:The 4-step method, involving identification, planning, execution, and evaluation, provides a structured framework for tackling problems. In the identification phase, _Step 1_, issues are precisely pinpointed, aiding in accurate problem definition, crucial for effective decision-making. For instance, in a business scenario, if sales decline is the issue, this step helps clarify if it's due to product quality, marketing, or market changes, enabling focused decision-making.
Moving to the planning phase, _Step 2_, where strategies and solutions are devised, this structured approach ensures that all potential solutions are thoroughly explored, enhancing the quality of decisions made. This step involves a rigorous evaluation of each potential solution, ensuring a comprehensive understanding of their viability and implications.
During the execution phase, _Step 3_, the structured plan is put into action, benefiting from the earlier clarity and well-thought-out decisions. For example, if a marketing strategy was identified as a solution, this phase would involve implementing the chosen strategy with a clear roadmap, minimizing errors and optimizing resources.
Lastly, the evaluation phase, _Step 4_, allows for the assessment of the implemented solution's effectiveness. By systematically analyzing the outcomes against predefined metrics, this step ensures continuous improvement and learning from the process, contributing to more informed decision-making in the future. This structured approach, therefore, not only facilitates effective decision-making but also ensures successful implementation and ongoing refinement of solutions.
Here is complete question;
"What are two benefits of following the 4-step method of problem-solving, and how do they contribute to effective decision-making and solution implementation?"
