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: 111 dollars
Step-by-step explanation:
7 hours on Saturday and 4 hours on Sunday
Sunday gets paid 1 1/3, or 4/3 times more which is 9 x 4/3 = 12 per hour
Saturday is 9 per hour
7x9 (Saturday) + 4x12 (Sunday) = 111 dollars
Answer:
-1/6
Step-by-step explanation:
You turn the problem into 1/2 x -1/3. Doing the equation you get -1/6
Answer:
Just substitute "x" with "3".
Step-by-step explanation:
y = 2.4x + 3.1
y = 2.4(3) +3.1
y = 7.2 + 3.1
y= 10.3
Answer: 10.3 minutes
