Solve xy − 9 = k for x. I WILL MARK BRAILIEST
Answer:
x = [tex]\frac{k+9}{y}[/tex]
Step-by-step explanation:
Given
xy - 9 = k ( add 9 to both sides )
xy = k + 9 ( isolate x by dividing both sides by y )
x = [tex]\frac{k+9}{y}[/tex]

Write the equation in slope-intercept form: 6x + 2y = 10.
Answer: y=-3x+5
Step-by-step explanation:
6x+2y=10
Solve for y
2y=-6x+10
y=-3x+5
Answer: y = -3x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b so all you need to do is put the equation into that format.
6x + 2y = 10
2y = 10 - 6x
y = -3x + 5

1) Mrs.Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
Step-by-step explanation:
Given the following expression;
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
x is the number of days since the games went on sale
In order to determine after how many days the revenue for each game wil be the same, we will equate M(d) to R(d)
M(d) = R(d)
x^2-9x-10 = 2x+10
x^2-9x-10 -2x-10 = 0
x^2-11x-20 = 0
factorize
x = 11±√121-4(-20)/2
x = 11±√121+80/2
x = 11±√201/2
x = 11±37.16/2
x = 11+37.16/2
x = 48.16/2
x = 24.06
Hence the revenue for each game will be the same after 24 days
It takes about 13 days for the revenue for each game the same.
Revenue is the amount of money made from selling a particular amount of products.
Given that the revenue is given by:
Math Game: M(d)=x²-9x-10
Reading Game: R(d)=2x+10
For both games to have the same revenue, hence:
M(d) = R(d)
x² - 9x - 10 = 2x + 10
x² - 11x - 20 = 0
x = -1.6 or x = 12.6
Since the number of days cannot be negative, hence it takes about 13 days for the revenue for each game the same.

f(x) = -6x + 4
f (x) = 28
Answer:
x = - 4
Step-by-step explanation:
Given f(x) = - 6x + 4 and f(x) = 28, then equating
- 6x + 4 = 28 ( subtract 4 from both sides )
- 6x = 24 ( divide both sides by - 6 )
x = - 4

Janie is three years younger than her brother chad the sum of their ages is 27 how old is Janie
Answer:
Janie is 12
Chad is 15
Step-by-step explanation:
27 - 3 = 24
24 : 2 = 12
12 + 3 = 15 (Chad)
27 - 15 = 12 (Janie)
Janie is three years younger than her brother Chad and she is 12 years old
Janie is 3 years younger than her brother Chad.
let
Chad age = x
Janie age = x - 3
The sum of there ages is 27. Therefore,
x + x - 3 = 27
2x - 3 = 27
2x = 30
divide both sides by 2
x = 30 / 2
x = 15
Chad age = 15 years
Janie's age = 15 - 3 = 12 years

Seats by the right = fit two people
Seats by the left = fit three people
This means, 1 row of seat can contain 5 persons
The back seat = 8 people can sit comfortably.
Hence, the number of people that can ride the bus at one time =
(14 × 5 people) + 8 people (backseat) + 1 driver
= 70 + 8 + 1
= 79 people

what is the area and perimeter of this triangle
Answer:
A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)
Step-by-step explanation:
the area of a triangle is half of its base times height.
the base and the height must be perpendicular to each other; so they would be 56 and 73.
56(73)/2=2044
the perimeter is the sum of all the sides
73+56+92=221
The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.
To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.
Area of a right-angled triangle:
The area of a triangle can be found using the formula:
A = (1/2) x base x height
Plugging these values into the formula, we get:
A = (1/2) x 73 cm x 56 cm
A = 2044 cm²
Therefore, the area of the right-angled triangle is 2044 cm².
Perimeter of a right-angled triangle:
The perimeter of a triangle is the sum of all its sides.
In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.
Perimeter = 73 cm + 92 cm + 56 cm
Perimeter = 221 cm
Therefore, the perimeter of the right-angled triangle is 221 cm.
