To simplify this expression we need, at first, to find like terms.
<span>-3x+5y-2+7x-8y</span><span>-3x+5 = (</span>-3x+7x)+ (5y-8y) -2+5 = 4x + 3y +3
4x + 3y +3 is the answer.
Answer:
Equity of taxation means each citizen pays an amount of tax equal to their income and ability to pay the tax.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• 1 + cot² x = csc²x and csc x = 
• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Consider the left side
sin²Θ( 1 + cot²Θ )
= sin²Θ × csc²Θ
= sin²Θ × 1 / sin²Θ = 1 = right side ⇔ verified
-----------------------------------------------------------------
Consider the left side
cos²Θ - sin²Θ
= cos²Θ - (1 - cos²Θ)
= cos²Θ - 1 + cos²Θ
= 2cos²Θ - 1 = right side ⇒ verified
