Answer: y = 3x - 19

Step-by-step explanation:

The equation of line in the slope intercept form is give as :

y = mx + c , where m is the slope and c is the y - intercept.

The points given : ( 4 , -7 )

slope = 3

Using the formula

y - y_{1} = m (x - x_{1} )

substituting the given values , we have

y - (-7) = 3 ( x - 4 )

y +7 = 3x - 12

y = 3x -12 - 7

y = 3x - 19

This gives the equation of the line in slope - intercept form.

Answer:

141000 * (1 - 0.016)^15 = 110699.48 = A 110700

Step-by-step explanation:

1st year depreciation = 141000 -  (141000 * 0.016) = 138744

2nd year depreciation = 138744 - (138744 * 0.016) = 136524.096

3rd year depreciation = 136524.096 - (136524.096 * 0.016) = 134339.710464

etc. unitl you reach the 15th year

Basically we calculate 1.6% of the current value of the house and subtract that from the current value for each year for 15 years.

The equation used in the answer is a faster way to approach your answer instead of calculating for each year.

You'd multiply your initial value by the difference in percentage (note well that since it is decreasing in value we subtract the decimal equivalent to 1.6% which is 0.016, from 1 where one represents 100% and then raise the difference gained to the power of the amount of years which would be 15.

Answer: 81

To get this answer, you do two things
1) Take half of the x coefficient 18 to get 9
2) Square the result from the previous step to get 9^2 = 9*9 = 81

This value is added on to get x^2+18x+81 which factors to (x+9)^2 confirming we have a perfect square trinomial
