What is a quadratic function?A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.
We can start by completing the square of the quadratic function g(k) = -k² + 6k - 9:
g(k) = -(k² - 6k + 9 ) = -(k - 3)²
Option A can be simplified as:
g(k) = -(k - 3)²
Compared with the completed square form of g(k), we can see that option A is equivalent to g(k).
Therefore, the answer is A. g(k) = -(k - 3)²

Use the properties of equality to solve the equation 3x+2-x=11x+9. State which property justifies your first step and why you chose it. Check your solution
The first step we'll make is subtraction property of equality and we choose this property to separate the variables and contsnts.
What are the properties of equality?Facts regarding any two or more quantities connected by the equal sign are known as properties of equality.
There are four types of properties of equality.
Addition property, when two equal quantities are increased by a common value, the equality is preserved.
Transitive property of equality, entities that are equivalent to one another are also equivalent to one another.
Subtraction property, equality is maintained when a common term is subtracted from two equal terms.
Multiplying by a common term do not alter the equality, according to the multiplication property of equality.
Given, An equation 3x + 2 - x = 11x + 9.
The first step would be subraction property of equality.
We'll subtract 2 from each side of the equation.
3x + 2 - x - 2 = 11x + 9 - 2.
3x - x = 11x + 7.
We choose subraction property of equality to separate the vriables and the constants.

Answer:
x=5 y=38
Step-by-step explanation:
180 degrees total minus the right angle (90) = 90... divide that by the two angels and its 45 each so for x; 45/3 = 5 for y; 45-7= 38
Answer:
y=−3x+83
x= −1 /3 y+ 83 /3
Step-by-step explanation:
right angles=90
triangles=180 degrees
180=3x+y+7+90
solve for x
3x+y+97=180
Add -y to both sides
3x+y+97+−y=180+−y
3x+97=−y+180
Add -97 to both sides
3x+97+−97=−y+180+−97
3x=−y+83
Divide by 3
x= −1 /3 y+ 83 /3
now solve for y
180=3x+y+7+90
Add -3x to both sides
3x+y+97+−3x=180+−3x
y+97=−3x+180
Add -97 to both sides
y+97+−97=−3x+180+−97
y=−3x+83

Answer:
v=12500-2500h
Step-by-step explanation:
Ok so to create this equation all you need to do is look at what information is given. You start with 12500 gallons of water so we know our equation is going to have 12500 in it.
So far our equation would look like this v=12500
The next information we are given is that it is decreasing by 2500 every hour so we know that we are going to be subtracting 2500 based on how many hours have went by so our equation would then look like this.
v=12500-2500h
we can check this by plugging in some numbers to see if it works. So at Zero hours we should still be at 12500
v=12500-2500(0)
v=12500
Ok so we know that it works for zero, but we should check at least one more number. We know that after 3 hours we would of lost 7500 gallons of water so it should equal 12500-7500=5000 gallons. Lets check this in our equation
v=12500-2500(3)
v=12500-7500
v=5000 Gallons

Answer:
the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
Step-by-step explanation:
The computation of the amount that he makes last week and in the year 2011 is as follows:
= Sale value of the stocks × earning percentage × number of weeks in a year
= $7,000 × 11% × 52 weeks
= $40,040
hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively

Rates Lin, Diego, and Elena are competing to see who can finish their book the fastest. Lin read the first 54 pages from a 270-page book in the first 3 days. Diego read the first 100 pages from a 320-page book in the first 4 days. Elena read the first 160 pages from a 480-page book in the first 5 days. If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:
Answer:
Diego will finish first while Lin and Elena would finish reading their book at the same time
Step-by-step explanation:
Rates Lin, Diego, and Elena are competing to see who can finish their book the fastest.
Their rates is calculated as:
For Lin
Lin read the first 54 pages from a 270-page book in the first 3 days.
54 pages = 3 days
270 pages = x
Cross Multiply
54x = 270 × 3
x = 270 × 3/54
x = 15 days
For Diego
Diego read the first 100 pages from a 320-page book in the first 4 days.
100 pages = 4 days
320 pages = x days
Cross Multiply
100x = 320 × 4
x = 320 × 4/100
x = 12.8 days
For Elena
Elena read the first 160 pages from a 480-page book in the first 5 days.
160 pages = 5 days
480 pages = x days
Cross Multiply
160x = 480 × 5
x = 480 × 5/160
x = 15 days
If they continue to read every day at these rates, who will finish first, second, and third?
Diego will finish reading his book first while Lin and Elena would finish reading their book at the same time
Answer:
Diego will finish first while Lin and Elena would finish reading their book at the same time
Problem Francine uses 2 3 3 2 start fraction, 2, divided by, 3, end fraction cup of pineapple juice for every 1 3 3 1 start fraction, 1, divided by, 3, end fraction cup of orange juice to make a smoothie.
Answer:
Pineapple juice = 2 cups
Step-by-step explanation:
Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie , how many cups of pineapple juice does Francine use for 1 cup of orange juice
Pineapple juice : Orange juice
2/3 cup : 1/3 cup
how many cups of pineapple juice does Francine use for 1 cup of orange juice
Let x = cups of pineapple juice
Pineapple juice : Orange juice
x cup : 1 cup
Equate the ratios
2/3 cup : 1/3 cup = x cup : 1 cup
2/3 ÷ 1/3 = x / 1
2/3 × 3/1 = x / 1
6/3 = x / 1
Cross product
6 * 1 = 3 * x
6 = 3x
x = 6/3
x = 2
Pineapple juice = 2 cups
