Answer:
41ft²
Step-by-step explanation :
8ft - 2ft = 6ft
6ft - 2ft = 4ft
4ft - 1ft = 3ft
3ft * (8ft + 2ft) / 2 = 15ft²
1ft * (8ft + 2ft) = 10ft²
8ft * 2ft = 16ft²
Total : 16 + 15 + 10 = 41ft²
PART A:
Finding the slope of the function f(x)
Choose any two pairs of coordinate from the table; (-1, -15) and (0, -10)
Let (-1, -15) be (x₁, y₁) and (0, -10) be (x₂, y₂)
Slope =
Slope of f(x) = 5
The function g(x) is given in the straight line equation form
Where, is the slope and is the y-intercept
Slope of g(x) = 2
-----------------------------------------------------------------------------------------------------------
g(x) = 2x + 8
Where, the slope (m) = 2 and the y-intercept (c) = 8
The y-intercept of g(x) is 8
for f(x), we can read the y-intercept when x = 0.
From the table, when x = 0, y = -10
The y-intercept of f(x) is -10
Function g(x) has higher y-intercept
It can tell you the general pattern or that it is far from the other points in scatter plot.
Ratio is white socks / brown socks
There are 8 white and 7 brown
Ratio = 8/7
-3x + y = 1 ............. the general form is y= mx +b .................y = 1 + 3x
...........................
Y = 3x + 1
