Answer: option A is the correct answer.
Step-by-step explanation:
The expression that relates revenue, profit and cost is
Profit = Revenue - Cost
The revenue from selling x shirts is r(x) = 11x. The cost of buying x shirts is c(x) = 6x + 20. Therefore,
p(x) = r(x) - c(x)
p(x) = 11x - (6x + 20)
By expanding the bracket, the minus sign will alter each term in the bracket. Therefore,
p(x) = 11x - 6x - 20
p(x) = 5x - 20

Answer:
3x < 4x < 3x + 8 < 4x + 3 < x² < x² + 6
Step-by-step explanation:
This is because as x → ∞
3x → 3∞ ,
Also, as x → ∞
4x → 4∞ ,
Also, as x → ∞
3x + 8 → 3∞ + 8,
Also, as x → ∞
4x + 3 → 4∞ + 3
,
Also, as x → ∞
x² → ∞²,
Also, as x → ∞
x² + 6 → ∞² + 6
and 3∞ < 4∞ < 3∞ + 8 < 4∞ + 3 < ∞² < ∞² + 6
Thus as x → ∞
3x < 4x < 3x + 8 < 4x + 3 < x² < x² + 6 in ascending order
Answer:
y= -4/9 + 1/9
Step-by-step explanation:
We have two coordinates here: (2, 225) & (5, 480)
Now, Calculate for the Slope:
m = y2-y1 / x2-x1
m = 480-225 / 5-2
m = 255/3
m = 85
y - y1 = m(x - x1)
y - 225 = 85(x - 2)
y - 225 = 85x - 170
y = 85x + 55
8x - y = -55 [ Final Equation in the standard form ]
B.) F(x) = 85x + 55
C.) For x=1, F(x) = 85(1) + 55 = 140
For x = 2, F(x) = 85(2) + 55 = 225
For x = 3, F(x) = 85(3) + 55 = 310
In short, Your Coordinates for the Graph would be: (1, 140) (2, 225), (3, 310)...
Hope this helps!
