Answer:
Increment in property per year ;
Slope of a linear function
Kindly check explanation for the rest of the answers.
Step-by-step explanation:
The rate of change is the increment in property value per year ; $220
Thsi corresponds to the gradient or slope of a linear function
If 1980 = x and x = 0
Recall :
y = bx + c
Where, b = slope = 220
x = year
y = property threshold
c = intercept value
In 1980, x = 0
y - intercept.
Put x = 0 into the equation :
4190 = 220x + c
4190 = 220(0) + c
4190 = c
3.)
The linear function becomes :
y = 220x + 4190
Property threshold in 2010:
x = 2010 - 1980 = 30
y = 220(30) + 4190
y = 6600 + 4190
y = 10,790
Property threshold in 2010
Year it will exceed 15000
15000 = 220x + 4190
15000 - 4190 = 220x
10810 = 220x
x = 10810 / 220
x = 49.136
That is, property threshold will exceed 15000 after 50 years
1980 + 50 = 2030
Year 2030

Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
