substitute this equation y=2/3x-1 if y=3
Answer:
I believe what your asking me to do is put the y value back into the equation and solve for x. If so x=6 or x=(5/9) SEE BELOW
Step-by-step explanation:
y=(2/3)x-1 , y=3
3=(2/3)x-1
4=(2/3)x
x=6
OR
y=2/(3x-1)
x=(5/9)

1/4 divided by 2/9. Input your answer as a reduced fraction.
Answer:
9/8
Step-by-step explanation:
The solution of the expression '1/4 divided by 2/9' in a reduced fraction is 9/8.
Used the concept of division which states that,
The division method is used to distribute a group of things into equal parts. The division is just the opposite of multiplications.
Given that,
1/4 divided by 2/9.
Now, divide the numbers and find the reduced fraction as,
1/4 divided by 2/9
It can be written as,
[tex]\dfrac{1}{4} \div \dfrac{2}{9}[/tex]
[tex]\dfrac{1}{4} \times \dfrac{9}{2}[/tex]

you look down at an object on the ground. If your eyes are
55 feet above the ground, and the angle of depression is 50º, how far is the object
from you?
i believe it’s 2,750 feet?
Answer:
We can think of this as a triangle rectangle.
We know that you eyes are 55ft above the ground, this can be one cathetus.
We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.
Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.
So we only know one angle and the opposite cathetus to this angle, then we can use the relation:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Then if we use this equation, we will get:
Sin(50°) = 55ft/hypotenuse
hypotenuse = 55ft/sin(50°) = 71.8 ft
This means that the distance between you and the object is 71.8 ft.
Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)
Answer:
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)
Step-by-step explanation:
Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are
(x - 3) and (x + 5)
The equation is the the product of the factors, that is
y = a(x - 3)(x + 5) ← a is a multiplier
To find a substitute (- 1, 8) into the equation
8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )
- [tex]\frac{1}{2}[/tex] = a
Then
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

Ben's Game World is having a sale on video games. The store is offering a sale pack of 4 video games for $43.80. What is the unit price of a video game in the sale pack?
Answer:
Answer:
a) 10.95
b) 76.65
Step-by-step explanation:
To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.
Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.

Which function has a removable discontinuity at x = 7?
9514 1404 393
Answer:
(b) see below
Step-by-step explanation:
A removable discontinuity exists when the function is undefined at a point where the limit exists.
Choices A, C, D have no limit at x=7 (does not exist).
__
Choice B can be simplified to ...
f(x) = (x -3)(x -7)/(x -7)
f(x) = (x -3) . . . . . . . x ≠ 7 (domain restriction; undefined at x = 7)
The discontinuity in this function can be removed by defining the function to be f(x) = x-3 everywhere.

george has opened a new store and he is monitoring its success closely. He has found that this store’s revenue each month can be modeled by r(x)=x2+5x+14 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars. He has also found that his expenses each month can be modeled by c(x)=x^2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.
the new store will sell 900 items in its fifth month in business
the store will have a profit of $900 after its fifth month in business
the store will have a profit of $5400 after its fifth month in business
the new store will sell 5400 items in its fifth month in business
Answer:
Step-by-step explanation:
The correct answer is that the new store will have a profit of $5400 after its fifth month.
Profit is given by subtracting revenue minus cost:
(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9
Using 5 for x,
(R-C)(5) = 9(5) + 9 = 45+9 = 54
This is in hundreds of dollars, so it represents $5400.
