Answer:
the vertex is ( 3 , 3)
Symetric axis‘s equation: x = 3
Step-by-step explanation:
Let‘s name the function ” f ”
f(x) = y = 2x² - 12x + 21
the vertex has coordinates of ( -b/2a , f(-b/2a) )
-b/2a = 12/2(2) = 12/4 = 3
f(-b/2a) = f(3) = 2(3)² - 12(3) + 21 = 3
then the vertex is ( 3 , 3)
the symetric axis has the equation :
x = -b/2a
then
A.) Rate of change = (1350 - 750) / (2010 - 2000) = 600/10 = $60
The initial value is the amount he charged in his first year of business which is $750.
B.) Required equation is given by y - 750 = 60x
y = 60x + 750 where x represent the number of years after 2000.
<span>A) Y= -5x+3
B) -x -7y = 13 substituting equation A) into B)
B) -x -7*(-5x +3) = 13
</span>
<span>B) -x +35x -21 = 13
B) 34x = 34
x = 1
</span>
<span>A) Y= -5*1 +3
A) Y= -2
</span>
What’s the question ? do you need the slope or the y intercept ?
Answer:
The more often your interest compounds, the more interest you'll earn on your investment. It's easy to see that money grows more quickly when it's earning compound interest than when it's earning simple interest
