Look at where both of the lines meet from there you can find that (-2,4) is the solution
The solution to the system of equations is (x, y) = (-2, 4).
Option B is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We can solve this system of equations by setting the expressions for y equal to each other and solving for x, then substituting the value of x into one of the equations to find the corresponding value of y.
y = x + 6 ...(1)
y = -0.5x + 3 ...(2)
Setting equations (1) and (2) equal to each other gives:
x + 6 = -0.5x + 3
Solving for x, we get:
x + 0.5x = 3 - 6
1.5x = -3
x = -2
Substituting x = -2 into equation (1), we get:
y = -2 + 6
y = 4
Therefore,
The solution to the system of equations is (x, y) = (-2, 4).

A company which uses the revaluation model for its PPE bought a building on 1 January 2014 for £50m. The building has an estimated useful life of 50 years and nil residual value. On 31 December 2018, the building was revalued at £40.5m and on 31 December 2020 it was revalued for a second time at £39m. The company uses the straight-line method of depreciation for all PPE items. There was no change to the remaining useful life after each revaluation. What is the net effect of both revaluations on the statement of comprehensive income?
Answer:
The net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.
Step-by-step explanation:
This can be determined using the following 3 steps:
Step 1: Calculation of the effect of first revaluation: from 01 January 2014 to 31 December 2018
Building cost = £50
Number of useful life = 50
Revalued amount on 31 December 2018 = £40.5m
Annual depreciation expenses from 01 January 2014 to 31 December 2018 = Building cost / Number of useful life = £50m / 50 = £1m
Number of years from 01 January 2014 to 31 December 2018 = 5
Total depreciation expenses from 01 January 2014 to 31 December 2018 = Annual depreciation expenses from 01 January 2014 to 31 December 2018 * Number of years from 01 January 2014 to 31 December 2018 = £1m * 5 = £5m
Net book value on 31 December 2018 = Building cost - Total depreciation expenses from 01 January 2014 to 31 December 2018 = £50m - £5m = £45m
Revaluation loss from the first revaluation = Net book value on 31 December 2018 - Revalued amount on 31 December 2018 = £45m - £40.5m = £4.50m
Step 2: Calculation of the effect of second revaluation: from 01 January 2019 to 31 December 2020
Revalued amount on 31 December 2020 = £39m
Number of useful life remaining after 31 December 2018 = Number of useful life - Number of years from 01 January 2014 to 31 December 2018 = 50 - 5 = 45
Annual depreciation expenses from 01 January 2019 to 31 December 2020 = Revalued amount on 31 December 2018 / Number of useful life remaining after 31 December 2018 = £40.5m / 5 = £0.90
Number of years from 01 January 2019 to 31 December 2020 = 2
Total depreciation expenses from 01 January 2019 to 31 December 2020 = Annual depreciation expenses from 01 January 2019 to 31 December 2020 * Number of years from 01 January 2019 to 31 December 2020 = £0.90 * 2 = £1.80
Net book value on 31 December 2020 = Revalued amount on 31 December 2018 - Total depreciation expenses from 01 January 2019 to 31 December 2020 = £40.5m - £1.80 = £38.70m
Revaluation surplus from the second revaluation = Revalued amount on 31 December 2020 – Net book value on 31 December 2020 = £39m - £38.70 = £0.30m
Step 3: Calculation of the net effect of both revaluations on the statement of comprehensive income
Net revaluation loss = Revaluation loss from the first revaluation - Revaluation surplus from the second revaluation = £4.50m - £0.30m = £4.20m
Therefore, the net effect of both revaluations on the statement of comprehensive income is a net revaluation loss of £4.20m that will reduce the comprehensive income by the exact amount of £4.20m.
The net effect of the revaluations on December 31, 2018 and December 31, 2020 is that the comprehensive income will reduce by £11 million.
Data and Calculations:
Cost of PPE on January 1, 2014 = £50 million
December 31, 2018:
Revaluation amount = £40.5 million
Revaluation Loss = £9.5 million (£50 million - £40.5 million)
New book value = £40.5 million
December 31, 2020:
Revaluation amount = £39 million
Revaluation Loss = £1.5 million (£40.5 million - £39 million)
New book value = £39 million
Total Revaluation Loss = £11 million (£9.5 + £1.5 million)
Thus, the net effect of both revaluations on the company's statement of comprehensive income is reduction of £11 million.

The area of a circle varies directly as the square of its radius. A circle with radius 2 in. Has area 12.568 in.^2 . What is the area of a circle with radius 6.4in.?
Answer:
[tex]A_2=128.69\ in^2[/tex]
Step-by-step explanation:
The area of a circle varies directly as the square of its radius.

Write an equation for the nth term of the arithmetic sequence.
2, 5, 8, 11, ...
Answer:
An equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]
Step-by-step explanation:
Given the sequence
2,5,8,11,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
here
a₁ = 2computing the differences of all the adjacent terms
d = 5-2 = 3, d = 8-5=3, d=11-8=3Using the nth term formula
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 2, d = 3
[tex]a_n=2+\left(n-1\right)3[/tex]
[tex]=2+3n-3[/tex]
[tex]=3n-1[/tex]
Thus, an equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]

The total price of five DVDs (all the same cost) and four movie tickets (all the same cost) is $138, whereas, the total price of two DVDs and five movie tickets is $96. What is the price of one movie ticket? Answer as a number with NO units and NO decimals. Only give the answer to the question asked.
Answer:
Step-by-step explanation:
Let the price of DVDS = x
The price of movie tickets = y
The total price of five DVDs (all the same cost) and four movie tickets (all the same cost) is $138,
= 5x + 4y = $138
The total price of two DVDs and five movie tickets is $96.
2x + 5y = $96
Hence:
5x + 4y = $138.... Equation 1
2x + 5y = $96..... Equation 2
What is the price of one movie ticket?
Elimination method
2y = 204
y = 204/2
y = 102
