3
Step-by-step explanation:
Looking at the first three values of the table- when the x increases by 1, the y increases by 3.
Answer:
(±1, -2)
Step-by-step explanation:
The co-vertices are the end points of the minor axis. The center is at (0, -2) and the minor axis is 2 units long, so the co-vertices are ...
(-1, -2) and (1, -2)
The answer to this problem is 9
( x + 5 ) ( x - 7 )
( x ) ( x ) + ( x ) ( - 7 ) + ( 5 ) ( x ) + ( 5 ) ( - 7 )
x² - 7x + 5x - 35
= x² - 2x - 35.
If the price is p and the quantity of bread sold is q = 400 - 100p, the average collection, in reais, depending on the price p, is given by R (p) = (400 - 100p). P
For this collection to be R $ 300.00, you must have:
(400 - 100p). p = 300 ⇔ 4p - p² = 3 ⇔ p² - 4p + 3 = 0 ⇔ p = 1 or p = 3
R $ 300.00
The current price is R $ 3.00, as R $ 300,000 / 100 = R $ 3
To maintain the collection, the price must be lowered to R $ 1.00 (R $ 0.50 <R $ 1.00 <R $ 1.50)
