In an equation of the form k = ax^2 + bx + c with a > 0, the least possible value of k occurs at x = -b/(2a). In the equation k = (6x + 12)(x - 8), what is the least possible value for k?
Answer:
[tex]k= 6x^{2} -36x-96[/tex]
Is what I got in a calculator but however, if you'd try and solve for K you won't get a complete answer.

2. You town got 3.44 inches of rain in June, 5.07 inches in July, and 4.28 inches in August. What was the average rainfall over these three month? Round to the nearest tenths of an inch.
Answer:
50% chance each time
each tim
Answer:
1. 1/6
2. 4.26 inches
Step-by-step explanation:
1. Because theres a chance youll land on heads 1/2 each time. Since its out of 3 you multiply 1/2*3 and get 1/6
2. Add all of the numbers, then divide by 3

2/3x - 12, x=18 (show work)
Answer:
0
Step-by-step explanation:
Since we know x=18, we need to find 2/3 of 18.
Let's make 2/3 so that the denominator(bottom part of a fraction) is 18.
18 divided by three is six so we needs to times the top number, 2, by 6.
The fraction would now be 12/18. Now we needs to subtracts 12 which would become 0/18. This equals 0.

Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 28, the sum of the squares is 65, and the sum of the cubes of the numbers is 407.
Answer:
Step-by-step explanation:
1) f(x) = x+y , xy = 49 --> f(x) = x+49/x
f '(x) = 1-49/x2 , x = ±√49 , choose x = +7
y = 49/x = 7
smaller = 7
larger = 7
2) Vertical Distance is difference between the two functions
V(x) = x+56 - x2, V '(x) = 1 -2x --> x = 1/2 --> V(1/2) = 56.25 <---Max Vertical distance
Boundary at -7 and 8 are less
3) I googled the equation, it is really y(n) = kn/(49+n2)
y '(n) = (k(49+n2) - 2kn2)/(49+n2) , Setting to zero, k(49+n2) -2kn2 = 0 , n = 7
4) Let x and y be the sides of the rectangle. A = xy = 37.5 Million or y = 37.5/x
The length of the fences is f(x) = 2x + 3y = 2x+112.5/x
f '(x) = 2-112.5/x2 --> x = √56.5 = 7.5 and y = 37.5/7.5 = 5 then scale by √Million
smaller = 5000 ft and larger = 7500 ft
this took me ages to work out so hopefully it helped
Answer:
x + y = 11
Step-by-step explanation:
xy = 28
x² + y² = 65
x³ + y³ = 407
(x + y)(x² - xy + y²) = x³ + y³
(x + y)(x² + y² - xy) = x³ + y³
(x + y)(65 - 28) = 407
37(x + y) = 407
x + y = 407÷37
x + y = 11
Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

BRAINLIST WILL BE GIVEN . to answer just just say for example graph one goes with equation 3 and table 4 . this was just a example not the answers . only answer if you know the answer .
9514 1404 393
Answer:
(graph, table, equation) = (1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)
Step-by-step explanation:
The graphs have the following (slope, intercept), so can be easily matched with the corresponding equation.
(1/2, 1), (2, -1), (1, 2), (1/2, -1), (-2, -1)
We can look at the points in the tables to see which graph they appear on.
Table 1, (-2, 3) is on graph 5
Table 2, (-3, -1) is on graph 3
Table 3, (-1, -3) is on graph 2
Table 4, (-2, -2) is on graph 4
Table 5, (4, 3) is on graph 1
__
Then our triples of graph, table, equation are ...
(1, 5, 2), (2, 3, 1), (3, 2, 4), (4, 4, 5), (5, 1, 3)

Find the Y-Intercept
-3x + 7Y = 21
Answer:
(0, 3)
Step-by-step explanation:
To find the y-intercept of a linear equation, we simply need to put the equation into "slope-intercept" form. This will allow the y-intercept to be shown as the constant being added to the equation. To put a linear equation into slope-intercept form, we simply need to solve for Y. Let's do that.
-3x + 7Y = 21
3x + -3x + 7Y = 3x + 21
7Y = 3x = 21
(1 / 7) * 7Y = (3x + 21) * (1 / 7)
Y = (3x / 7) + (21 / 7)
Y = 3x/7 + 3
Now that we have the Y isolated, we can see the constant being added is 3. Hence, the y-intercept is (0,3) since by definition the y-intercept is the point at which the line crosses the x axis (where x = 0). If you plug x=0 into the equation, you get Y = 3.
Cheers.

If $(2x+5)(x-3)=14$, find the sum of the possible values of $x$.
Answer:
x = 1/4 ± 1/4√233
Step-by-step explanation:
(2x + 5)(x - 3) = 14
~Use FOIL on the left side
2x² - 6x + 5x - 15 = 14
~Combine like terms
2x² - x - 15 = 14
~Subtract 14 to both sides
2x² - x - 29 = 0
~Use the quadratic formula and simplify
x = 1/4 ± 1/4√233
Best of Luck!
