Answer:
[tex]k=-8[/tex]
Step-by-step explanation:
We have the two points: (2, -3) and (k, 7).
And we want to find the value of k such that the slope between these two points is -1.
So, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (2, -3) be (x₁, y₁) and let (k, 7) be (x₂, y₂). Let's also substitute the slope m for -1. This gives us:
[tex]-1=\frac{7-(-3)}{k-2}[/tex]
So, let's solve for k. Add in the numerator:
[tex]-1=\frac{10}{k-2}[/tex]
Notice that we can rewrite the left side as:
[tex]\frac{-1}{1}=\frac{10}{k-2}[/tex]
Now, we can cross-multiply:
[tex]-(k-2)=10[/tex]
Divide both sides by -1. This removes the negative on the left:
[tex]k-2=-10[/tex]
Finally, add 2 to both sides. So, the value of k is:
[tex]k=-8[/tex]
And we're done!
The owner of a landscape company gave a survey to customers asking them to rate the quality of the
work of the crew that did their landscaping. Each respondent rated the quality as high, medium, or low.
The data were compiled and reported in the table, which shows the relative frequency of each rating
by row. A total of 70 people responded about the quality of the work of Crew B. How many of these
people gave Crew B a rating of "high"?
Answer:
35
Step-by-step explanation:
14 of these people gave Crew B a rating of high.
What is the relative frequency?A relative frequency reflects how frequently a certain type of occurrence occurs in relation to the overall number of observations. It is a frequency type that employs percentages, proportions, and fractions.
Given that, A total of 70 people responded about the quality of the work of Crew B. relative frequency of crew B getting high as the rating is 0.200.
Hence,
the number of people who gave B a rating of "high" = 0.200* 70 = 14
Therefore, from the survey owner get to know that 14 out of 70 people think that crew B does work of high quality.

diego paid $27 to have 3 pizzas delivered and $35 to have 4 pizzas delivered.
What is the price of one pizza
Answer:
9 or 8.25
Step-by-step explanation:
27/3=9
35/4=8 3/4
To find the price of one pizza, we can set up a system of equations based on the given information. Let's assume that the price of one pizza is "x" dollars.
From the first scenario, we know that Diego paid $27 to have 3 pizzas delivered. Thus, we can write the equation:[tex]3x = 27[/tex] From the second scenario, we know that Diego paid $35 to have 4 pizzas delivered. Thus, the equation becomes: [tex]4x = 35[/tex] To solve this system of equations, we can use the substitution method .
From the first equation, rearranging it to solve for "x," we find: [tex]x = 27/3 x = 9[/tex]Substituting the value of "x" into the second equation, we find:[tex]4(9) = 35 36 = 35[/tex] This means there is no solution, indicating that there might be an error in the given information.
However, if we assume an average price for each pizza, we can calculate it. The average price per pizza can be found by dividing the total amount spent by the number of pizzas. Thus, for both scenarios combined, Diego spent $62 on 7 pizzas, leading to an average price of: [tex]62/7 ≈ $8.86[/tex]Therefore, the estimated price of one pizza is approximately $8.86.

emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695. find the number of packages of erasers and pencils that were sold
Given :
Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.
To Find :
The number of packages of erasers and pencils that were sold .
Solution :
Let, number of erasers are x and pencils are y.
So, x + y = 220 ....1
Also, 2x + 5y = 695 ....2
Solving equation 1 and 2, we get :
[tex]2(220-y)+5y = 695\\\\440 - 2y + 5y = 695\\\\3y = 255\\\\y=85[/tex]
x = 220 - 85 = 135
Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.
Hence, this is the required solution.

1. Using the diagram below, answer the following question. Arthur is at the coordinate A(20,35), Cameron is at the coordinate C(65,40), and Jamie is at the coordinate J(45,20).
Arthur kicks the ball to Cameron in the soccer game. Jamie wants to intercept the ball at the midpoint of the distance between Arthur and Cameron. What is the coordinate of the midpoint that Jamie must run towards? Write your answer as a decimal, if necessary.
Answer:
(42.5, 37.5)

How might you prove your observations about the slope of a midsegment in part d using algebra and x- and y-coordinates? Briefly outline an approach using what you know about midpoints and parallel lines. Use the figure you created in GeoGebra to guide you.
Answer: I can use variables to represent the coordinates of the vertices for a general triangle ABC. then I can calculate the midpoints of the sides in terms of the same variables, and calculate the slope of each midsegment showing that the expression for the slope of a midsegment is the same as the expression for the slope of the third side of the triangle proves that the two are parallel.

V = 216 in.
Finn designs a sculpture that he wants to
display on stacked cubes. If his sculpture
is 1 foot tall, what will be the total
height of the display after he places the
sculpture on the three stacked cubes?
Explain.
V = 512 in.
V = 1,000 in.
Answer:
The total height of the display would be 36 inches tall.
Step-by-step explanation: The bottom cube would be 10 inches tall because 1,000 cubed would be 10 inches. The cube root of 512 would be 8, and the cube root of 216 would be 6. To find the height of the display you would need to add the height of each cube, plus the foot tall sculpture.

Step-by-step explanation:

The value of x using vertical angle is 20.
Thus, option (A) is correct.
Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. When two lines intersect at a point, they create four angles around that point. The two pairs of opposite angles are called vertical angles.
Each pair of vertical angles is congruent, meaning they have equal measures.
Given:
<TRS = x + 40
<VRW = 3x
From the figure, the angles <TRS and <VRW are vertical angles.
So, <TRS = <VRW
x+ 40 = 3x
To do this, subtract x from both sides of the equation:
x + 40 -x = 3x - x
40 = 2x
Dividing both sides of the equation by 2:
40 /2 = x
x= 20
So, the solution is x= 20.
Thus, option (A) is correct.
