Bert earns $35,000 gross annual salary. in bert's jurisdiction there is a progressive tax system with rules as follows: any amounts earned up to $20,000 are taxed at x%. any amounts earned beyond $20,000 are taxed at 20%. given that bert pays $4,500 per annum in income tax, calculate x. give your answer to the nearest tenth of a percent. do not include the percent symbol in your answer.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
