The graph of y = 4 – is shown.
Ratling [72]
Rather than try to select the correct answer without doing work, I'd rather do the work first and the matching later.

Given y = 4 - x, or    y = 4 - 1x,

1) the y-intercept is (0,4).
2) this being a linear function, it has neither maximum nor minimum.
3) the x-intercept is found by letting y = 0 and solving for x:  0 = 4 - x; x - 4.  The x-intercept is (4,0).

Which of the given statements is true?

Henry is up for retirement after 35 long years at his pharmacy. Before retiring, he would like to know how much he would receive
satela [25.4K]

To find how much Henry can expect to receive from Social Security on a monthly basis, we first need to find how much he cant expect to receive from social security per year.

We know form our problem that Henry averaged an annual salary of $45,620, so to find how much can Henry expect to receive from Social Security per year, we just need to find the 42% of $45,620.

To find the 42% of $45,620, we are going to convert 42% to a decimal by dividing it by 100%, and then we are going to multiply the resulting decimal by $45,620:

\frac{42}{100} =0.42

Social security annual payment = (0.42)($45,620) = $19,160.40

Since there are 12 month in a year, we just need to divided the social security annual payment by 12 to find how much he can expect to receive each month.

Social security monthly payment = \frac{19,160.40}{12} = $1.596.70

We can conclude that Henry can expect to receive $1.596.70 monthly from Social Security.
