We need to express this statement into a equation:
First of all. We will walk through the statement step by step into a mathematical language, so:
1. The sum of five and x:
x + 5
2. Twice the sum of five and x:
2(x + 5)
3. Eight less than x:
(x-8)
Finally the whole statement is:
4. <span>Twice the sum of five and x is eight less than x:
</span>
2(x + 5) = (x-8)
2x + 10 = x - 8
x = -18
215 - 44.49 (I added the two deductions mentally) = 170.51
I see the percentages 2%, 1% and 3% add up to 6%
So we want 6% of 215 or .06 x 215 = $12.90
$170.51 - 12.90 = $157.61 net income.
When you add a positive value to the argument of a function, its graph shifts to the left, the same number of units added to the argument.
This is, the graph of f(x+a) is the graph of the function f(x) shifted a units to the left.
Then, g(x) is f(x+3) = (x+3)^2
For the graph of y-5=5x only (-2,-5) is a point, (2,12) is not a point but when 2 is x it is (2,15)
