<span>Cost of material =$84
Selling Price of each bracelet=$3.50
Let b be the number of bracelets to be sold.
Let P be the profit.
To get a profit Selling price should be greater than cost price.
Profit = Selling Price - Cost price
$3.50 * b would give the total selling price.
Therefore,
P=3.50b - 84</span>
No, quadrilaterals have to have 4 right angles
The area of the circle with a diameter of 3 inches is 7.07 in2
The answer is B because n can be greater than or equal to
Answer:
Step-by-step explanation:
y = 2x - 3 --------------(i)
y = x² - 2x - 8 -----------(ii)
Substitute y = x² - 2x - 8 in equation (i)
x² - 2x - 8 = 2x - 3
x² - 2x - 8 - 2x + 3 = 0
x² - 2x -2x - 8 + 3 = 0
x² - 4x - 5 = 0
x² + 1x - 5x -5 = 0
x(x + 1) - 5(x + 1) = 0
(x + 1)(x - 5) = 0
x + 1 =0 ; x -5 = 0
x = -1 ; x = 5
When x = -1; y =2*(-1) - 3 = -2 -3 = -5
When x = 5; y = 2*5 - 3 = 10-3 = 7
