22,000÷100= 220
1% = £220 depreciation
15 % = 220×15= 3,300
45% = 3,300×3=9,900
22,000-9,900= £12,100
final answer is £12,100 after 3 years .
An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =
I hope this helped :)
Even though you didn't bother to share the list of acceptable choices ...
that short group of inequalities that the question calls "the following" ...
we can give you the answer anyway.
The graph depicts the inequality
<em> y > -2 x + 6</em> .
