Explanation: 3 x 2 + 10 x + 3 We can Split the Middle Term of this expression to factorise it. In this technique, if we have to factorise an expression like a x 2 + b x + c , we need to think of 2 numbers such that: N 1 ⋅ N 2 = a ⋅ c = 3 ⋅ 3 = 9 and, N 1 + N 2 = b = 10 After trying out a few numbers we get: N 1 = 9 and N 2 = 1 9 ⋅ 1 = 9 , and 9 + ( 1 ) = 10 3 x 2 + 10 x + 3 = 3 x 2 + 9 x + 1 x + 3 = 3 x ( x + 3 ) + 1 ( x + 3 ) ( 3 x + 1 ) ( x + 3 ) is the factorised form for the expression.

Answer:
b. – 0.4(x + 1.6) = 1.6
Step-by-step explanation:
Cost function, 
Revenue function, 
Profit function, 
Break point
.
Fixed cost
$
.
Variable cost
$
.
Price of item
$
.
Let
be the number of items produced and sold.
a) Cost function
Fixed cost
variable cost \times number of items
So, 
b) Revenue
Price of an item
number of items
So, 
c) Profit
Revenue
Cost



d) <u>Break even point</u> 



.
So, the product should be produced for
or more items.

Answer:
y+2=2/3(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=2/3(x-3)
y+2=2/3(x-3)
