Why you think individuals should receive a credit or deduction for this expense?
max2010maxim [7]

A deduction can only lower your taxable income and the tax rate that is used to calculate your tax. This can result in a larger refund of your withholding. A credit reduces your tax giving you a larger refund of your withholding, but certain tax credits can give you a refund even if you have no withholding.

Answer:

  B. 5x−(−4x−6)=10

The first equation gives an expression for y:

  y = -4x -6

When that is used in the second equation, the result is ...

  5x -y = 10

Burka [1]
Answer:
question (1)
height of building = 308 ft
question (2)
cos 67.11 = 7/18

Explanation:
question (1)
Taking a look at the triangle, we can see that it is a right-angled triangle. This means that we can apply the special trigonometric identities.
The one we will use here is:
tan Θ = opposite / adjacent 
where:
Θ = 72
the opposite side is the height of the building
the adjacent side = 100 ft
Substitute to get the height as follows:
tan(72) = height / 100
height = tan(72)*100 = 307.76 which is approximately 308 ft

question (2):
We are given that:
cos Θ = 7/18
therefore:
Θ = cos^-1(7/18)
Θ = 67.114 
approximating to the nearest tenth, we would find that:
Θ = 67.11°

Hope this helps :)
