A caterer charges $275 for 15 people and $425 for 25 people. The cost, y, is a linear function of the number of x people. Write an equation in slope-intercept form for this situation. *
Answer:
The equation of the given situation is y = 15x + 50
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope b is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ A caterer charges $275 for 15 people
∵ A caterer charges $425 for 25 people
∵ x represents the number of people
∵ y represents the cost
∴ (x1, y1) = (15, 275)
∴ (x2, y2) = (25, 425)
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{425-275}{25-15}=\frac{150}{10}[/tex]
∴ m = 15
→ Substitute it in the form of the equation above
∴ y = 15x + b
→ To find b substitute x by 15 and y by 275
∵ 275 = 15(15) + b
∴ 275 = 225 + b
→ Subtract 225 from both sides
∴ 275 - 225 = 225 - 225 + b
∴ 50 = b
→ Substitute it in the equation
∴ y = 15x + 50
∴ The equation of the given situation is y = 15x + 50

Answer:
2876 books
Step-by-step explanation:
If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...
y1 = 12841 +24.25x
y2 = 48072 +12x
These costs will be equal when ...
y1 = y2
12841 +24.25x = 48072 +12x
12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x
x = 2876 . . . . . . . . . . divide by 12.25
The costs will be the same for production of 2876 books.

Find the equation of the linear function represented by the table below in slope intercept form.
Answer:
Y=1x-7
Step-by-step explanation:
First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)
y-6 = 1x -1 then get y by itself
y=1x-7
What mathematical formula do you use for the following question. A rectangle whose perimeter is 104 feet has a length that is 12 feet longer than its width what is the area of the rectangle. The answer is 640 square feet 20 feet wide by 32 feet long.
Answer:
Width = 20 inches and Length = 32 inches
Area of rectangle = 640 feet²
Step-by-step explanation:
Perimeter of rectangle = 104 feet
Let width of rectangle = x
Length of rectangle = x+12
We need to find area of rectangle.
First we need to find value of x
The formula used to calculate perimeter of rectangle is: [tex]Perimeter= 2(Length+Width)[/tex]
Putting values and finding x
[tex]Perimeter= 2(Length+Width)\\104 = 2(x+12+x)\\104=2(2x+12)\\104=4x+24\\4x=104-24\\4x=80\\x=\frac{80}{4}\\x=20[/tex]
So, Value of x= 20
So, Width x= 20 inches
Length = x+12 = 20+12 = 32 inches
So, Width = 20 inches and Length = 32 inches
Now finding Area
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding area
[tex]Area=Length\times Width\\Area=20\times 32\\Area=640 \ feet^2[/tex]
Area of rectangle = 640 feet²

Suppose you observe a star orbiting the galactic center at a speed of 1300 km/skm/s in a circular orbit with a radius of 18 light-days. Calculate the mass of the object that the star is orbiting.
Answer: 1.1818^37 kg
Step-by-step explanation:
Given that:
Orbit speed = 1300 km/s
Radius (r) = 18 light days
Mass of object the star is orbiting :
Using the relation :
M = rv² / G
Where ; r = Radius in m ; v = velocity in m/s
G = 6.67 * 10^-11 = gravitational constant
18 light days in meters = 4.662 * 10^14 m
v = 1300km/s to m/s
v = (1300 * 1000)m /s = 1300000 m/s = 1.3 * 10^6 m/s
Hence ;
M = (4.662 * 10^14 * (1.3 * 10^6)^2 / (2/3) * 10^-10
M = (4.662 * 10^14) * (1.69 * 10^12) / (2/3) *10^-10
M = (7.87878 * 10^26) / 6.67 * 10^-11
= 1.1818^37 kg

Ross wants to know what interest rate he needs to make his $800 grow to
$1000 in 4 years.
Answer:
Why?:
The interest formula is A = P(1+r/m)^mt
A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.
So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent. (I'm not super confident, so see if you have other answers)

Yes, the triangles are congruent.
SSS
Answer:
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
In each problem, angle C is a right angle. Solve each triangle rounding answers to the nearest

Answer:
c = 17.8, A = 25.7°, B = 64.3°
Step-by-step explanation:
Side c can be found from the Pythagorean theorem:
c = √(a² +b²)
c = √(7.7² +16²) = √315.29
c ≈ 17.8 . . . feet
__
The tangent relation is ...
Tan = Opposite/Adjacent
tan(A) = a/b = 7.7/16
A = arctan(7.7/16)
A ≈ 25.7°
B = 90° -25.7°
B = 64.3°

The expressions to represent the costs of each club is $10 + ($15 * m)
Let's begin by writing expressions for the costs of each club:
Multiplayer Madness:
Joining Fee: $50 (one-time payment)
Monthly Fee: $0 (since it's not mentioned, we assume there's no additional monthly fee)
The total cost for Sharleen to join Multiplayer Madness would be the joining fee only, which is $50.
Games Galore:
Joining Fee: $10 (one-time payment)
Monthly Fee: $15 (recurring monthly charge)
The total cost for Sharleen to join Games Galore would be the joining fee plus the cumulative monthly fees over time. Let's represent the total cost of Games Galore as a function of the number of months (m) Sharleen stays in the club:
Total Cost of Games Galore = Joining Fee + (Monthly Fee * Number of Months)
Total Cost of Games Galore = $10 + ($15 * m)
