Answer:
30×5=150
so 150+10=160
thus his payment in the 30th installment is
rs.160
Equation if the line for the graph is
y = -2x+1
Answer:
c = 2
Step-by-step explanation:
Substitute x = 1 + i into the equation
(1 + i)² - 2(1 + i) + c = 0 ← distribute left side
1 + 2i + i² - 2 - 2i + c = 0 ( note that i² = - 1 )
1 + 2i - 1 - 2 - 2i + c = 0 ← collect like terms on left
- 2 + c = 0 ( add 2 to both sides )
c = 2
Answer:
-3x^2+100x-1500
Step-by-step explanation:
Create an equation for the total cost.
1500+200x
1500 is the fixed cost, plus the additional 200 it costs to create a scooter.
Then you need to subtract that from the revenue, which is provided in a function. 300x-3x^2
[300x-3x^2] - [1500+200x]
Solve.
100x - 3x^2 -1500
Write in standard form.
-3x^2+100x-1500
