Answer: Casey bought 4 1/2 pounds of apples
The equation is 0.88x - $1.50 = 2.46
x is the unknown number of pounds of apples.
0.88 is the cost per pound, 0.88x is the total cost of the apples before the discount .The discount is $1.50 $2.46 is the cost after the discount.
Part b Step-by-step explanation:
0.88x - $1.50 = 2.46 . Add $1.50 to both sides
0.88x - $1.50 + $1.50 = 2.46 + 1.50
On left, 1.50-1.50=0 so "cancels' on the right, add $2.46 + 1.50 = 3.96
0.88x = 3.96 is the cost before discount . Divide both sides by .88
.88x/.88 = 3.96/.88 . .88/.88 = 1 so 1 'cancels' leaving x. 3.96/.88 = 4.5
x = 4.5
part c
4.5 is 4 1/2, the (previously unknown) number of pounds of apples.
Casey bought 4 1/2 pounds of apples.
Answer:
The answer to your question is letter A
Step-by-step explanation:
Data
x² - 6x + y² - 6y = -9
Process
1.- Find the center
x² - 6x + ( )² + y² - 6y + ( )² = -9
x² - 6x + (3)² + y² - 6y + (3)² = -9 + 9 + 9
(x - 3)² + (y - 3)² = 9
Center = (3, 3)
radius = 3
See the graph below
2.- From the previous information and the graph, we conclude that the equation intercepts the y-axis in (0,3)
