Find the values of x and y.

(2x+25)+(3x-10)=180

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)

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.

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.

The sum of the 8 terms of the series 1-1-3-5- ... -13 is -48

The given sequence is:

1,-1,-3,  . . -13

and there are 8 terms.

The related series of this sequence is:

1-1-3-5- ... -13

Notice that the series is an arithmetic series with:

first term, a(1) = 1

common difference, d = -1 - (1) = -2

last term, a(8) = -13

To find the sum of the series, use the sum formula:

S(n) = n/2 [(a(1) + a(n)]

Substitute n = 8, a(1) = 1, a(n) = a(8) = -13 into the formula:

S(8) = 8/2 [1 + (-13)]

S(9) = 4 . (-12) = -48

Answer:

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.

Using linear function concepts, it is found that since the two lines have the same slope, they are parallel.

A linear function is modeled by:

y = mx + b

In which:

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.

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

b = 2

Hence, the solution of the system of equations is (a , b) = (3 , 2).

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)

=20

We know that,

Sn=n2[2a+(n-1) d]

∴S10=102⋅ [2(2) +(10-1) (2)]

=5⋅ [4+(18)]

=5⋅ [22]

=110

Hence, the 10th term of the given series is 20, and the sum of the first 10th term is 110.

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.

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
