Answer:
The missing coordinate [tex]r[/tex] is 9.
Step-by-step explanation:
Given the points [tex]P(x,y) = (-3,-3)[/tex] and [tex]Q(x,y) = (5,r)[/tex], the slope of a line passing the two points ([tex]m_{PQ}[/tex]) is determined by equation of secant line:
[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)
[tex]m_{PQ} = \frac{r-(-3)}{5-(-3)}[/tex]
If we know that [tex]m_{PQ} = \frac{3}{2}[/tex], then the value of [tex]r[/tex] is:
[tex]\frac{3}{2} = \frac{r+3}{8}[/tex]
[tex]12 = r + 3[/tex]
[tex]r = 9[/tex]
The missing coordinate [tex]r[/tex] is 9.

Step-by-step explanation:
Student Council is selling tickets to the Winter
Dance. Tickets cost $5 per person or $8 per
couple. To cover expenses, at least $1200
worth of tickets must be sold. No more than 500
students can fit in the gym where the dance is
being held.
List two combinations of tickets that could be sold, so
that Student Council makes a profit, yet stays under the
room capacity.
Answer:
Two possible combinations are;
1) 200 single and 30 couples
2) 150 single and 57 couples
Step-by-step explanation:
The given parameter in the question are;
The cost of ticket per person = $5
The cost of tickets per couple = $8
The minimum worth of tickets to be sold = $1,200
The maximum number of students that can fit in the gym = 500
Let 'x' represent the number of single persons that attend the dance and let 'y' represent the number of couple that attend, we have;
5·x + 8·y ≥ 1,200
x + y ≤ 500
Making 'y' the subject of both equations gives;
y ≥ 150 - 5·x/8
y ≤ 500 - x
From the graph of the inequalities created with Microsoft Excel, we have;
When x = 200, and y = 30, we get;
5 × 200 + 8 × 30 = 1240 > 1200
200 + 30 × 2 = 460 < 500
We also have;
x = 150, and y = 57, we get
Equating both values of 'y', we get;
5 × 150 + 8 × 57 = 1206 > 1200
150 + 57 × 2 = 264 < 500
Therefore, from the acceptable region in the graph, we have the following two possible combinations
1) 200 single and 30 couples
2) 150 single and 57 couples

please help!!! - The price of an item has been reduced by $1.08. The new sale price is $98.75. What was the original price?
Answer:
my answer is 106.65 that is times
Answer:
$99.83
Step-by-step explanation:
The original price was lowered by $1.08, so the new price is $1.08 less than the original. Since the new price is $98.75, subtract $1.08 to get the original price. $98.75- 1.08= $99.83

Step-by-step explanation:
−7y+4=60
Subtract 4 from both sides.
−7y=60−4
Subtract 4 from 60 to get 56.
−7y=56
Divide both sides by −7.
y=−56/7
Divide 56 by −7 to get −8.

When would you use a pictograph? to compare change over time if the data is numerical to save space for a large set of data if the data is categorical
Answer:
to save space for a large set of data
if the data is categorical
Step-by-step explanation:
The pictograph is used if the data is categorical
What is a pictograph?A pictograph is a type of graph that uses pictures or symbols to represent data. It is best used when the data is categorical or non-numerical. For example, a pictograph can be used to show the favorite types of fruits of a group of people or the most popular colors of a group of cars.
Pictographs are useful for presenting data in a visually appealing way that is easy to understand, especially for younger or less experienced readers. They are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.
Given data ,
Let the pictograph be represented as A
Now , pictographs are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.
For example, if you want to show how the population of a city has changed over the years, a line graph or a bar graph would be a better choice than a pictograph
Hence , pictographs are useful if there is categorical data

what is the surface area
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
Answer:
748 ft²
Step-by-step explanation:
For the surface area, you need to add up the area of all sides, six in this example, but it can be simplified into three by multiplying some of them by two as its presumed a rectangle
x1 = 5*14*2 = 140
x2 = 16*14*2 = 448
x3 =16*5*2 = 160
You find the sum of these; 140 + 160 + 448 = 300 + 448 = 748

Answer:
im not sure but i think its e,c,f
Step-by-step explanation:
Answer:
55 °
Here's the way i got my answer :
Complementary angles are two angles that have a sum of 90° ,therefore 35° + X = 90°
X=55° .
to get ∠DBF
180° - 90° = 90 °
to get ∠EBF
∠CBD + ∠DBE + ∠EBF = 180°
35° + 90° + ∠EBF = 180°
∠EBF = 55°
Complete the square
to find the vertex
of this parabola.
x?+8y+2x - 23=0
Answer:
The vertex of the parabola is;
([-1], [3])
Step-by-step explanation:
The given quadratic equation is presented as follows;
x² + 8·y + 2·x - 23 = 0
The equation of the parabola in vertex form is presented as follows;
y = a·(x - h)² + k
Where;
(h, k) = The vertex of the parabola
Therefore, we have;
x² + 8·y + 2·x - 23 = 0
8·y = -x² - 2·x + 23
y = 1/8·(-x² - 2·x + 23)
y = -1/8·(x² + 2·x - 23)
y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)
y = -1/8·((x + 1)² - 24) = -1/8·(x + 1)² + 3
Therefore, the equation of the parabola in vertex form is y = -1/8·(x + 1)² + 3
Comparing with y = a·(x - h)² + k, we have;
a = -1/8, h = -1, and k = 3
Therefore, the vertex of the parabola, (h, k) = (-1, 3).
