Answer:
how many tries do you have?
I think its d because the proportion 6/4 and LM/6 cuz the smaller number is on the bottom? I dont know try it. how many tried do you have?
Its either d or b
Answer:
(4, -25)
Step-by-step explanation:
One thing I wanted to say is thank you for including the equation to find the vertex! I literally had a brain fart and was like wait it is -b over 2a, then I looked and high fived myself lol but anyways. But anyways the question is what is the vertex of x²-8x-9??
First let's label this formula. The quadratic formula has three variables to label and it labels them as a,b, and c.
a= x² b= -8 c=-9 ( and yes the negative and positive sign makes a difference, trust me. :D )
So again what is the vertex equation? It is -b over 2a. So let's look at our functiion and plug in the numbers.
b= -8 => -b= -(-8) = +8
a= 1 => 2a= 2(1) = 2
So -b/2a equals a positive 8 divided by 2. 8 divided by two equals.. 4.
Yet what would be outcome of this equation. How about we input 4 into the equation we have.
f(x)= x²-8x-9
f(4)= (4)²-8(4)-9
f(4)= 16-(32)-9
f(4)= -16-9
f(4)= -25
So in this case (4, -25) is the vertex of this equation!!
Sorry for typing so much, I know it may be alot, but it's the answer. Yet, I really do hope I gave you a very clear answer. If you have any questions or comment, don't be afraid to say ask or even message me. If you have to. But anyways I hoped I help, have a great day!! :D

Answer:
what are we supposed to solve
Answer:
(A) x=5
Step-by-step explanation:
- The length of the pool is 20 feet,
- The width is (20 minus x) feet; and
- The area of the pool is 300 square feet.
Area = Length X Width
300 =20(20-x)
Opening the bracket on the right hand side
300 =400-20x
20x=400-300
20x=100
Divide both sides by 20
x=5
The value of x=5
