How do you find the point slope form for the points (2,7) and (-1,9)?
Answers
Answer:
y = -2/3 x + 25/3
Step-by-step explanation:
The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.
Our equation needs to be in y = mx + b form.
We can plug in (2, 7) as our (x, y) and find b:
7 = -2/3 (2) + b
b = 7 + 4/3 = 25 / 3.
Therefore, our equation is y = -2/3 x + 25/3
Use the Equation(in the picture) and plug in your variables to find m(slope)
[tex]\frac{9-7}{-1-2} = \frac{-2}{3} = -0.67[/tex]

A resort hotel in Scottsdale, AZ charges $1800 to rent a reception hall, plus $58 per person for dinner and open bar. The reception hall can accommodate up to 200 people. a) Write a function, T, to represent the total cost to rent the reception hall if n people attend the reception.
Answers
Answer:
T(n) = 1800 + 58n
Step-by-step explanation:
Rent reception = $1800
Charge per person = $58
Number of person who attend reception = n
Total cost = fixed cost + variable cost
Fixed cost = 1800
Variable cost = 58n
Total cost = T(n)
Total cost = fixed cost + variable cost
T(n) = 1800 + 58n

[tex]x=67.38^\circ[/tex]
Step-by-step explanation:
Use trigonometry
Recall that cos(x)=adjacent side/hypotenuse
You can remember this with SohCahToa
Also remember that if cos(x)=y then [tex]cos^{-1}(y)=x[/tex]
In this case, we know the adjacent side and hypotonous
Adjacent side=5000
Hypotenuse=13000
Therefore
[tex]Cos(x)=\frac{5000}{13000}=\frac{5}{13}[/tex]
Now to solve for x, take the inverse cosine
[tex]cos^{-1}(\frac{5}{13})=x=67.38^\circ[/tex]

If the relationship is proportional, what is the missing value from the table? x / y 8 / 6 16 / ? 24 / 18 answers under here! 8,a 9,b 12,c 14,d ADD ANSWER
Answers
The correct option is Option C: the missing value is 12.
What is the directly propotional?In directly proportionality, if one quantity increases then the other quantity also increases. if one quantity decreases then other quantity also decreases.
x ∝ y
⇒ x= ky
where k is proportionality constant.
Here the value x1, y1 is given by
x1=8
y1=6
as x1 is directly proportional to y1.
x1 = ky1
⇒8=6k
⇒k= 8/6
⇒k =4/3
If x3= 24 then x3 =ky3
⇒24=(4/3)y3
⇒y3= 24/(4/3)= 18 which is true from the table
Then given in the question x2=16
As x2 is directly proportional to y2.
x2 ∝ y2
⇒ x2 =ky2
where k= 4/3
⇒ 16 = (4/3)y2
⇒ y2= 16/(4/3)
⇒y2= 16*3/4
⇒y2= 12
The correct option is Option C: the missing value is 12.

Against the Lady Huskies, the Lady Bears scored 65 points on 30 field goals (2- and 3-point goals). How many 2-point goals and how many 3-point goals did they make?
Answers
Answer:
The team scored 25 2-point goals and 5 3-point goals
Step-by-step explanation:
Here, we are interested in calculating the number of 3 points and 2 points goals scored by the team
let the number of two point goals be x while the number of three point goals be y
The total goal number is 30;
Hence;
x + y = 30 ••••••(i)
Also, the total point is 65
point of two points goals is 2 * x = 2x
points of three point goal is 3 * y = 3y
Adding both;
2x + 3y = 65 ••••••(ii)
So we have two equations to solve simultaneously.
From 1, x = 30 -y
Now substitute this into ii
2(30-y) + 3y = 65
60 -2y + 3y = 65
y = 65 -60
y = 5
x = 30 - y
x = 30-5 = 25

Gere has 3 times as many shirts with print patterns as he does shirts in solid colors. He has a total of 16 shirts. How many shirts in print patterns does he have ?
Answers
Answer:
He has 12 print patterns shirt
Step-by-step explanation:
Here, we are interested in calculating the number of print colored shirts owned by Gere.
From the question, we are told that he has 3 times shirts with print colors as shirts with solid colors.
This means that if the number of solid colored shirt he has is x, then he has 3x print shirts
The addition of both is 16;
hence;
x + 3x = 16
4x = 16
x = 16/4
x = 4
Since number of print shirts = 3x; this means there are 3 * 4 = 12 print shy
