Answer:
A.
Gradient: 4
x-intercept: (1,0)
y-intercept: (0,-4)
B.
Gradient: - 3
x-intercept: (-1,0)
y-intercept: (0,-3)
Line y=5x=40
x-intercept: 8
y-intercept: 40
Step-by-step explanation:
y -5x = 40
x-intercept: 0-5x=40
-5x = 40. x = 40/-5
x = -8
y-intercept: y -0 = 40
y = 40
Answer:
Whole numbers include 0 while natural numbers do not.
Step-by-step explanation:
Natural numbers are 1, 2, 3, 4, etc.
Whole numbers are 0, 1, 2, 3, 4, etc.

P(1) = 37,100
P(4) = 58,400
The linear equation (for x ≥ 1)
P(x) = 37,100 + a(x-1)
For x = 4
58,400 = 37,100 + a(4-1)
58,400 - 37,100 = 3a
21300 = 3a
a = 7100
So, the linear equation:
P(x) = 37100 + 7100*(x-1)
P(x) = 37100 + 7100x - 7,100
P(x) = 7100x + 30000
To find when the profit should reach 108100, we can substitute P(x) by 108100.
108100 = 7100x + 30000
108100 - 30000 = 7100x
78100 = 7100x
x = 78100/7100
x = 11
