function below?
f (n) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5)
Answer:
Ste = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5)vp-by-step explanation:
To find the zeros of function, write in factors form,
[tex]f(n)=(-4n+3)(3n+5)[/tex]
Quadratic function :Given function is,
[tex]f(n)=-12n^{2} -11n+15[/tex]
We have to break into factor form to find the zeros of function.
[tex]f(n)=-12n^{2} -11n+15\\\\f(n)=-12n^{2}-20n+9n+15\\ \\f(n)=-4n(3n+5)+3(3n+5)\\\\f(n)=(-4n+3)(3n+5)[/tex]

Answer:
see explanation
Step-by-step explanation:
Evaluate u for each value of n by substituting value of n into u, that is
n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9
n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0
n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1
n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12
Thus

Which of the following equations is equivalent to 3x + 4y = 15?
The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4 so option (A) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
Given the expression,
3x + 4y = 15
4y = 15 -3x
y = 15/4 - 3x/4
Hence "The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4".

PLSSS HELP!! For the given ordered pairs, write a function rule relating x and y. (1,4), (2,9), (3,16), (4,25)
Answer:
y=(x+1)^2
Step-by-step explanation:
we have the following
[tex]x=1;y=4\\\\x=2;y=9\\\\x=3;y=16\\\\x=4;y=25[/tex]
the values of y are squares so we can write
[tex]x=1;y=2^{2} \\\\x=2;y=3^2\\\\x=3;y=4^2\\\\x=4;y=5^2[/tex]
so as you can see when
[tex]x=n;y=(n+1)^2[/tex]
so our relation is
[tex]y=(x+1)^2[/tex]
If sin Ѳ = cos 40, find the value Ѳ
Answer:
Θ = 50°
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x)
Given

Answer:
Ѳ = 50
Step-by-step explanation:
Sin Ѳ = cos 40
[tex]Ѳ = \sin ^{ - 1} ( \cos(40) ) [/tex]
Simplify
[tex]Ѳ = sin^{ - 1} (0.7660444431) \\Ѳ = 50[/tex]
What is 7x-6=9x+6? PLEASE HELP ME!!!!!!!!!!!!!
Answer:
x=-6
Step-by-step explanation:
7x-9x=6+6
-2x=12
x=-6
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
7x - 6 = 9x + 6
Step 2: Subtract 7x on both sides
-6 = 2x + 6
Step 3: Subtract 6 on both sides
-12 = 2x
Step 4: Divide both sides by 2
-6 = x
Step 5: Rewrite

What is the equation of the line that passes through the point (2,-6)and has a slope of −1?
Step-by-step explanation:
Hey there!!
Just simply work with it.
We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.
So, just do accordingly.
The point is (2,-6) and slope is -1.
[tex](y - y1) = m(x - x1)[/tex]
Where, "m" is a slope.
Put all values.
[tex](y + 6) = - 1(x - 2)[/tex]
Simplify them to get answer.
[tex](y + 6) = - x + 2[/tex]
[tex]y = - x - 4[/tex]
Therefore the equation is y= -x-4 OR can be written as x+y+4=0.

Given: -7(x+2)+4x=6(2x-4); Prove x=2/3
Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x

Which of the Following is the solution to 4|x+3| greater than equal to 8? Options are as followed: A.x less then equal to -5 or x greater than equal to -1 B. x greater than equal to -1 C.x less then equal to -5 and x greater than equal to -1 D. x greater then equal to -5 and x greater then equal to -1
Answer:
A
Step-by-step explanation:
4|x+3| >= 8
Divide both sides by 4
4|x+3| / 4 >= 8/4
|x+3| >= 2
Rewritten as
-2 >= x + 3 >= 2
Subtract 3 from all sides
-2 - 3 >= x + 3 - 3 >= 2 - 3
-5 >= x >= -1
Or
-1 <= x <= -5
x less then equal to -5 or x greater than equal to -1
In a small business, 40 of the employees are men and 30 of the employees are women. What is the ratio of women to men?
Answer:
3 : 4
Step-by-step explanation:
Men = 40, Women = 30
Ratio of women to men
[tex] = \frac{30}{40} = \frac{3}{4} = 3 : 4 \\ [/tex]
The Ratio of the women to men is 3/4.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, In a small business, 40 of the employees are men and 30 of the employees are women.
Since There are 30 women on 40 men in the company
Thus, ratio of the women to men = 30/40
The ratio of the women to men = 3/4
Therefore, the ratio of women to men is 3/4 in the organization.

Answer:
So the value of s = 7 cm
Step-by-step explanation:
We know that, Area of a triangle = 1/2 * b * h
So, base = 24 cm
height = s
Area = 1/2 * b * h
=>84 = 1/2 * 24 * h
=>84 = 12 * h
=>84 / 12 = h
=> 7 = h (in cm)

One of the most common algebraic symbols is the use of x, y or another letter of the alphabet to indicate a variable or unknown quantity. Common symbols used in algebra also include those related to equality, inequality, factorials and organization, like braces, brackets and parentheses.
Give brainiest please ;-;
Answer:
different variables represent unknown numbers.
Step-by-step explanation:
For example the equation 5x = 15
X is a variable that represents an unknown number. To get the unknown number in the example you need to divide 15 by 5 and 5 by 5 to get X alone and then X will equal 3.
So 5×3=15

Find NQ if NP = 13 cm and line l is a segment bisector.
Answer:
NQ = 26 cm
Step-by-step explanation:
A line bisector divides a line into two equal segments.
Given that line l is the bisector of segment NQ, it then means it divides NQ into two equal segments, namely, segment NP and segment PQ.
Thus, NP = ½ of segment NQ
Therefore, if NP = 13 cm,
13 = ½*NQ
multiply both sides by 2
2*13 = NQ
26 = NQ
NQ = 26 cm
