Answer:
y=-3x+50
Step-by-step explanation:
y=50-3x ,where x is number of days.
The correct answer is (C)!
Since the area of the circle is 400π, 150π/400π = 135/360.
Answer:
x = 5/2,2
Step-by-step explanation:
The answer is <span>a.)(x - 4)2 = 3.
(x - a)</span>² = b can be expressed as:
x² - 2ax + a² = b ⇒ x² - 2ax + a² - b = 0
Our equation is x² - 8x + 13 = 0.
The general formula is x² - 2ax + (a² - b) = 0
Thus:
8x = 2ax and a² - b = 13
Divide both sides of the first equation (8x = 2ax) by x:
8 = 2a ⇒ a = 8 ÷ 2 = 4
Replace a in the second equation (a² - b = 13):
4² - b = 13 ⇒ b = 4² - 13 = 16 - 13 = 3
Now when we have a and b, let's just replace them in the general equation:
(x - a)² = b
(x - 4)² = 3
Answer:
15
Step-by-step explanation:
8+8 would be the doubles and that would equal 16.
Then take one away from 16 and that would equal 15
