Solve for variable 24a-22=-4(1-6a)
Answer:
a = undefined/no real solution
Step-by-step explanation:
Expand
24a - 22 = -4 + 24a
24a - 24a = -4 + 22
0a = 18
a = undefined/no real solution (when something is divided by 0 it becomes undefined)
The equation 24a - 22 = -4(1 - 6a) have no solution for the variable "a".
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Given:
equation 24a - 22 = -4(1 - 6a)
1. Distribute the -4 to the terms inside the parentheses:
24a - 22 = -4 + 24a
2. Simplify the equation by combining like terms:
24a - 22 = 24a - 4
3. Rearrange the equation by moving all the terms involving "a" to one side and the constant terms to the other side:
24a - 24a = -4 + 22
4. Simplify 24a - 24a = -4 + 22:
0 = 18
The equation 0 = 18 is not true, which means there is no solution.

Convert 214 pounds to kilograms. Use 1 kg = 2.2 lb.
Answer:
97.27 kg
Step-by-step explanation:
1kg = 2.2 lb
214 lb = ?kg
Make it into an equation:
1 kg/ 2.2 lb = ?kg / 214 lb
? = 1kg x 214lb ÷ 2.2 lb
?= 214lb ÷ 2.2 lb
? ≈ 97.27 kg / 214 pounds
Verify :

What is different about the solutions to an inequality (like r > -3) with that of an equation (like
= 2)?
When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.

1.1 Factoring x2-12x+20
The first term is, x2 its coefficient is 1 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is +20
Step-1 : Multiply the coefficient of the first term by the constant 1 • 20 = 20
Step-2 : Find two factors of 20 whose sum equals the coefficient of the middle term, which is -12 .
-20 + -1 = -21
-10 + -2 = -12 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and -2
x2 - 10x - 2x - 20
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-10)
Add up the last 2 terms, pulling out common factors :
2 • (x-10)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-10)
Which is the desired factorization

Theory - Roots of a product
2.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
2.2 Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
Solving a Single Variable Equation:
2.3 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
Supplement : Solving Quadratic Equation Directly
Solving x2-12x+20 = 0 directly
Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula
Parabola, Finding the Vertex:
3.1 Find the Vertex of y = x2-12x+20
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 + 20.0
or y = -16.000
Parabola, Graphing Vertex and X-Intercepts :
Root plot for : y = x2-12x+20
Axis of Symmetry (dashed) {x}={ 6.00}
Vertex at {x,y} = { 6.00,-16.00}
x -Intercepts (Roots) :
Root 1 at {x,y} = { 2.00, 0.00}
Root 2 at {x,y} = {10.00, 0.00}
Solve Quadratic Equation by Completing The Square
3.2 Solving x2-12x+20 = 0 by Completing The Square .
Subtract 20 from both side of the equation :
x2-12x = -20
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 :
-20 + 36 or, (-20/1)+(36/1)
The common denominator of the two fractions is 1 Adding (-20/1)+(36/1) gives 16/1
So adding to both sides we finally get :
x2-12x+36 = 16
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 = 16 and
x2-12x+36 = (x-6)2
then, according to the law of transitivity,
(x-6)2 = 16
We'll refer to this Equation as Eq. #3.2.1
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. #3.2.1 we get:
x-6 = √ 16
Add 6 to both sides to obtain:
x = 6 + √ 16
Accordingly, B2 - 4AC =
144 - 80 =
64
Applying the quadratic formula :
12 ± √ 64
x = —————
2
Can √ 64 be simplified ?
Yes! The prime factorization of 64 is
2•2•2•2•2•2
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).
√ 64 = √ 2•2•2•2•2•2 =2•2•2•√ 1 =
± 8 • √ 1 =
± 8
So now we are looking at:
x = ( 12 ± 8) / 2
Two real solutions:
x =(12+√64)/2=6+4= 10.000
or:
x =(12-√64)/2=6-4= 2.000
x=10
x=2

how do i find thedegree of a pollygon????
Answer:
Not sure what you mean, but I'm assuming you're referring to the sum of all the interior angles of a polygon. In that case:
Total sum of interior angles of a polygon ->
[tex]{180(n-2)[/tex]
However, if you are looking for the degrees of each interior angle, you must divide the total interior angle degrees by the amount of sides on the polygon, n
Degree of each interior angle of a polygon ->
[tex]\frac{180(n-2)}{n}[/tex]
In both cases, n represents the amount of sides the polygon has.

If f=(9/5 x c ) +32 85c =__f
Answer:
185
Step-by-step explanation:
Answer:
It entirely depends upon an individual.
It’s a known fact that humans need social interaction. Lack of which can affect their social behaviour and mindset. Whilst most would agree that e-learning is widely preferred by the younger generation, it is undeniably detaching them from social interactions.
When kids or students are engrossed in learning online, they’re missing out on social interactions that can open various doors of the mind, be it creative or observational skills. It’s understood that e-learning allows an individual to study far and beyond the subject and gives them an opportunity to explore multiple fields of their interest, one can’t ignore that it chains them to the system as well.
The deal-breaker in such a situation is an individual. If they demand social interaction, they would keep their digital device aside for once and would get indulge in social interaction. If they’re of another kind, they would prefer spending their days and nights just exploring and reading about new things online.
So, in my opinion, it’s quite subjective to narrow down the overall benefits and drawbacks of e-learning.

To find m, we can use the formula y2 - y1 / x2 - x1
x1 = 2
y1 = 50
x2 = 4
y2 = 90
Let's plug these numbers into our formula.
m = 90 - 50 / 4 - 2 = 40/2 = 20
So far our equation looks like: y = 20x + b
Now, let's plug one of the points into our equation.
50 = 20(2) + b
Simplify
50 = 40 + b
Subtract 40 from both sides.
10 = b
The final equation is: y = 20x + 10

Write the equation of the parabola in vertex form.
vertex (0,3), point (1,-4)
f(x) =
Answer:
f(x) = 7x² + 3Step-by-step explanation:
vertex form of an equation of the parabola:
f(x) = a(x - p)² + q
vertex (0, 3) ⇒ p = 0, q = 3
so:
f(x) = a(x - 0)² + 3
f(x) = ax² + 3
the parabola goes through point (1, -4) ⇒ x=1, f(x)=-4
-4 = a(1)² + 3
-4 = a + 3
a = 7
Therefore the equation of the parabola in vertex form:
f(x) = 7x² + 3

Keiko purchased a prepaid phone card for $20 . Long distance calls cost 16 cents a minute using this card. Keiko used her card only once to make a long distance call. If the remaining credit on her card is $17.28 , how many minutes did her call last?
Answer:
17 minutes
Step-by-step explanation:
To answer this question, all we have to do is subtract the original amount of money on the phone card by what is remaining after Keiko's call:
20 - 17.28 = 2.72
Now, we divide this number by 0.16:
2.72 / 0.16 = 17
So, Keiko's call lasted 17 minutes

The point shows the coordinates of (-2,1) and (4,6).
Now, When two points are given on a st.line, we use double point formula.
So, use formula;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Put all values of x and y coordinates.
[tex](y - 1) = \frac{6 - 1}{4 + 2} (x + 2)[/tex]
Simplify it.
[tex](y - 1) = \frac{5}{6} (x + 2)[/tex]
[tex]y = \frac{5}{6} x + 2 \times \frac{5}{6} + 1[/tex]
[tex]y = \frac{5}{6} x + \frac{ 8}{3} [/tex]
Therefore, the equation of a line is y= 5/6x+8/3.
