The equation of the axis of symmetry is x = 6
How to find the equation of the axis of symmetry?The equation of the parabola is given as:
y = 2x^2 - 24x + 86
Differentiate the equation of the parabola
So, we have
y' = 4x - 24
Set the differentiated equation of the parabola to 0
So, we have
4x - 24 = 0
Add 24 to both sides of the differentiated equation of the parabola
4x = 24
Divide both sides of the differentiated equation of the parabola by 4
x = 6
This represents the the axis of symmetry
Hence, the equation of the axis of symmetry is x = 6

The values of the square numbers are:
a. -16
b. 16
c. 16
How to evaluate the valuesFrom the information given, we have the following expressions;
-4²(-4)²4²Let's write the squares in simpler form
-4² = - (4 × 4)
This is so because the square was only assigned to 4 and not the negative sign
(-4)² = - 4 × - 4
This is so because the square was assigned to both the negative sign and 4
4² = 4 × 4
This is so because the square was assigned to 4
Now, we have
- (4 × 4) = -16
- 4 × - 4 = 16
4 × 4 = 16
Thus, the values are - 16, 16 and 16 respectively.

The South Shore community of Bay Shore has 7,482 homes it. The Turf Tec team recently installed a new turf field at the HS football stadium. It took the team the entire summer, 12 weeks to finish the job. The team consisted of 12 laborers earning $65 per hour and 4 Supervisors earning $85 per hour. They worked 10 hours a day for 6 days a week, Monday thru Saturday. The new turf cost $15,000 per piece. The field needs 15 pieces. Find: a) Total Labor Cost b) Total Product Cost c) Total Cost d) Cost per Home e) Cost per Week
Using proportions, the costs are given as follows:
a) Total Labor Cost: $806,400.
b) Total Product Cost: $225,000.
c) Total Cost = $1,031,400.
d) Cost per home = $137.85.
e) Cost per week = $85,950.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, the labor cost is found using the earnings of the workers, as follows:
12 weeks x 6 days x 10 hours x (12 laborers x 65 per hour + 4 supervisors x 85 per hour).
Hence:
L = 12 x 6 x 10 x (12 x 65 + 4 x 85) = $806,400.
For item b, the product cost is the cost of the turf, hence:
15 pieces x $15,000 per piece
15 x 15,000 = $225,000.
For item c, the total cost is the sum of the product cost and the labor cost, hence:
Total Cost = 806,400 + 225,000 = $1,031,400.
For item d, the cost per home is found dividing the total cost by the 7,482 homes, hence:
Cost per home = 1031400/7482 = $137.85.
For item e, the cost per week is found dividing the total cost by the 12 weeks, hence:
Cost per week = 1031400/12= $85,950.

Using linear function concepts, it is found that since the two lines have the same slope, they are parallel.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.When two lines are parallel, they have the same slope.
The first road goes through points (0, 16) and (20,0), hence the slope is:
m = (0 - 16)/(20 - 0) = -0.8.
The second road goes through points (0,8) and (10,0), hence the slope is:
m = (0 - 8)/(10 - 0) = -0.8.
Since the two lines have the same slope, they are parallel.

Evaluate each series to the given term. 2+4+6+8+ . . . . . . ; 10 th term
Finding the value of any term in a given sequence is known as an arithmetic sequence if each term in the sequence is equidistant from the terms before and after. To find any term in a sequence, we first have to find the pattern of the sequence. Then we can multiply the distance between any two terms by one less than the number of terms we are looking for. Adding this to the first term gives you the term you want.
Here the first term a=2,
Common difference d=4-2=2
We know that,
f(n)=a+(n-1) d
f (10) =2+(10-1) (2)
=2+(18)

We know that,

Solve the following:
-(6x + 6) +2=-6x-3
Answer:
no solution
Step-by-step explanation:
- (6x + 6) + 2 = - 6x - 3 ← distribute parenthesis on left side and simplify
- 6x - 6 + 2 = - 6x - 3
- 6x - 4 = - 6x - 3 ( add 4 to both sides )
- 6x = - 6x + 1 ( add 6x to both sides )
0 = 1 ← not possible
this indicates the equation has no solution
Answer:
No Solution, 0 = 1
Step-by-step explanation:
a) Simplify both sides of the equation.
−(6x + 6) + 2 = −6x − 3
−6x+ −6 + 2 = −6x + −3
(−6x) + (−6 + 2) = −6x − 3
−6x + −4 = −6x − 3
−6x − 4 = −6x − 3
b) Add 6x to both sides.
−6x − 4 + 6x = −6x − 3 + 6x
−4 = −3
c) Add 4 to both sides.
−4 + 4 = −3 + 4

Describe the similarities and differences between a common difference and a common ratio.
The similarity between common difference and common ratio is that both are used to find the next term, but common difference is added while common ratio is multiplied.
Common difference (d) is defined as the difference between consecutive terms in an arithmetic sequence. It is determined by subtracting the term from the preceding term. For example, in an arithmetic sequence 2, 5, 8, 11,…, the common difference is 5-2=3 or 8-5=3.
The sequence will be: a, a+d, a+2d, a+3d,… a+nd.
In the general form:
d=an -an-1, where an is the nth term and an-1 is the preceding term.
Common ratio (r) is defined as the quotient between consecutive terms in a geometric sequence. It is determined by dividing the term by the preceding term. For example, in an geometric sequence 2, 4, 8, 16,…, the common ratio is 4/2=2 or 8/4=2.
The sequence will be: a, ar, ar^2, ar^3,…ar^n.
In the general form:
r=an/an-1, where an is the nth term and an-1 is the preceding term.
Hence, both common difference and common ratio shows relationship between consecutive terms in a sequence. Common difference is added to the term to find the next term while common ratio is multiplied to the term to find the next term.

By elimination, the solution of the system of equations, 2a + 3b = 12 and 5a - b = 13, is (a , b) = (3 , 2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in a and b, a variable should be eliminated by adding/subtracting the two equations.
Multiply first equation 2 by 3.
5a - b = 13 (equation 2)
15a - 3b = 39
Adding the two equations will eliminate the variable b.
2a + 3b = 12 (equation 1)
15a - 3b = 39 (equation 2)
17a = 51
a = 3
Substitute the value of a to any of the two equations and solve for b.
2a + 3b = 12 (equation 1)
2(3) + 3b = 12
3b = 12 - 6
3b = 6

What are rational and irrational numbers?Rational numbers are numbers that can be represented by fractions, such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.Irrational numbers are numbers that cannot be represented by fractions, being non-terminating and non-repeating decimals, such as non-exact square roots.To order numbers on the number line, we have that:
For negative numbers, the smaller the integer part is, the greater is the number, for example -2 > -3.For positive numbers, the greater the integer part is, the greater is the number, for example 3 > 2.If the integer parts are equal, we look at the decimal part, following the same logic as above.

Suppose you want to determine exactly where the lines y=2x-7/4 and y = 3 - 3x intersect. Use algebra to determine the point of intersection and be
prepared to explain your method.
The point of intersection of the lines would be (19/20, 3/20) which are the lines y=2x-7/4 and y = 3 - 3x intersect each other.
To determine exactly where the lines y = 2x-7/4 and y = 3 - 3x intersect.
We need to find where both lines are intersect,
Thus, we would be required to equate them
⇒ 2x - 7/4 = 3 - 3x
Rearrange the likewise terms in the above equation,
⇒ 2x + 3x = 3 + 7/4
Apply the addition operation, and we get
⇒ 5x = 19/4
⇒ x = 19/(4)(5)
⇒ x = 19/20
Substitute the value of x = 19/20 in the equation y = 3 - 3x, we get
⇒ y = 3 - 3(19/20)
⇒ y = 3 - 57/20
⇒ y = 3/20
Therefore, the point of intersection of the lines would be (19/20, 3/20)
