Answer:

$1,197.71

Step-by-step explanation:

The 6.2% Social Security tax applied to the first $90,000 of earnings in 2005, so Jackson is due to be refunded the tax he paid on more than that amount.

6.2% × (74,007 +35,311 -90,000) = 6.2% × 19,318 = $1,197.71

Jackson should receive a Social Security tax refund of $1,197.71.

_____

<em>Comment on rounding</em>

The tax on 74,007 will be rounded down, as will the tax on 35,311. So, the overpayment value calculated here needs to be rounded down to correspond to the actual to-the-penny amount of overpayment.

Write the slope-intercept equation of the function f whose graph satisifies the given conditions.

viva [34]

The general form for a straight line is y = mx + c where m is slope and c is y-intercept.

Two lines are perpendicular when the product of their slopes = -1

Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2

So a line perpendicular to the given and has the same y-intercept is

y = (-7/3) x - 2
