Step-by-step explanation:
Plug in -3 for n in the equation:
[tex]w(n) = n^2 - n[/tex]
[tex]w(-3) = (-3)^{2} - (-3)[/tex]
Simplify. Remember to follow PEMDAS. First, solve the power:
[tex]w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)[/tex]
Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:
[tex]w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12[/tex]
Your answer: [tex]w(-3) = 12[/tex]

What is the solution to 5(2n+4)=−2(4n−1) ?
Answer: n= -1
Step-by-step explanation:
simplify by distributing:
5(2n+4)=-2(4n-1)
10n+20=-8n+2
add 8n to both sides:
10n+20=-8n+2
+8n +8n
————————
18n+20=2
subtract 20 from both sides
18n+20=2

divide both sides by 18:

HELP ILL GIVE BRAINLIEST!! Andrea is planning on taking the train to go to the beach, a train travels at a constant speed. An equation relating the distance traveled in miles, m, to the number of minutes, t is t = 3m . If Andrea arrived at the beach in an hour and 15 minutes, how much distance did she travel?
Answer:

Hello!
To solve the problem, we need to understand what it means. The distance traveled in miles is represented with t, while the number of minutes is represented with m.
Now, first we need to fill in the equation with the information we're given.
t = 3m → t = 3(1 [tex]\frac{1}{4}[/tex])
Now, we solve for t.
t = 3(1 [tex]\frac{1}{4}[/tex]) → t = 3 [tex]\frac{3}{4}[/tex]
Andrea traveled 3 [tex]\frac{3}{4}[/tex] in an hour and 15 minutes.

Solve for x.
3x/2 = 15
x = 10 1/2
x = 1/10
x=22 1/3
x = 10
Answer:
x = 10
Step-by-step explanation:
3x/2 = 15
cross multiply
3x = 15 × 2
3x = 30
divide both sides by the coefficient of x
3x/3 = 30/3

what are the solutions of 4(x+6)^2=52
ANSWER: 1.211 or 13.211
Step-by-step explanation:
STEP
1
:
1.1 Evaluate : (x-6)2 = x2-12x+36
Trying to factor by splitting the middle term
1.2 Factoring x2-12x-16
The first term is, x2 its coefficient is 1 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is -16
Step-1 : Multiply the coefficient of the first term by the constant 1 • -16 = -16
Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is -12 .
-16 + 1 = -15
-8 + 2 = -6
-4 + 4 = 0
-2 + 8 = 6
-1 + 16 = 15
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Equation at the end of step

x2 - 12x - 16 = 0

Parabola, Finding the Vertex
2.1 Find the Vertex of y = x2-12x-16
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 6.0000
Plugging into the parabola formula 6.0000 for x we can calculate the y -coordinate :
y = 1.0 * 6.00 * 6.00 - 12.0 * 6.00 - 16.0
or y = -52.000
Parabola, Graphing Vertex and X-Intercepts :
Root plot for : y = x2-12x-16
Axis of Symmetry (dashed) {x}={ 6.00}
Vertex at {x,y} = { 6.00,-52.00}
x -Intercepts (Roots) :
Root 1 at {x,y} = {-1.21, 0.00}
Root 2 at {x,y} = {13.21, 0.00}
Solve Quadratic Equation by Completing The Square
2.2 Solving x2-12x-16 = 0 by Completing The Square .
Add 16 to both side of the equation :
x2-12x = 16
Now the clever bit: Take the coefficient of x , which is 12 , divide by two, giving 6 , and finally square it giving 36
Add 36 to both sides of the equation :
On the right hand side we have :
16 + 36 or, (16/1)+(36/1)
The common denominator of the two fractions is 1 Adding (16/1)+(36/1) gives 52/1
So adding to both sides we finally get :
x2-12x+36 = 52
Adding 36 has completed the left hand side into a perfect square :
x2-12x+36 =
(x-6) • (x-6) =
(x-6)2
Things which are equal to the same thing are also equal to one another. Since
x2-12x+36 = 52 and
x2-12x+36 = (x-6)2
then, according to the law of transitivity,
(x-6)2 = 52
We'll refer to this Equation as Eq. #2.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x-6)2 is
(x-6)2/2 =
(x-6)1 =
x-6
Now, applying the Square Root Principle to Eq. #2.2.1 we get:
x-6 = √ 52
Add 6 to both sides to obtain:
x = 6 + √ 52
Since a square root has two values, one positive and the other negative
x2 - 12x - 16 = 0
has two solutions:
x = 6 + √ 52
or
x = 6 - √ 52
Solve Quadratic Equation using the Quadratic Formula
2.3 Solving x2-12x-16 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -12
C = -16
Accordingly, B2 - 4AC =
144 - (-64) =
208
Applying the quadratic formula :
12 ± √ 208
x = ——————
2
Can √ 208 be simplified ?
Yes! The prime factorization of 208 is
2•2•2•2•13
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 208 = √ 2•2•2•2•13 =2•2•√ 13 =
± 4 • √ 13
√ 13 , rounded to 4 decimal digits, is 3.6056
So now we are looking at:
x = ( 12 ± 4 • 3.606 ) / 2
Two real solutions:
x =(12+√208)/2=6+2√ 13 = 13.211
or:
x =(12-√208)/2=6-2√ 13 = -1.211
Answer: X=root of14 -6; x = -root of14 -6
