Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3
+ 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3 + 7x - 40 = 60
⇒ 0.3 + 7x - 100 = 0
⇒ 3 + 70x - 1000 = 0
⇒ x = -70 ± 
× 
⇒ x = -70 ± 130 ×
⇒ x = 10 or -
Quantity sold cannot be negative giving us the value of x as 10 units.

Answer:
The slope should be 8 1/3 which is also 25/3
Step-by-step explanation:
Answer:
rhombus sides are equal.
7y=4y+21
7y-4y=21
3y=21
y=21/3
y=7
3x=45°(by alternate interior angle)
x=45/3
x=15
