Answer: x=4
Step-by-step explanation: 0.75x+3=6(x−3)
0.75x+3=(6)(x)+(6)(−3)
0.75x+3=6x+−18
0.75x+3=6x−18
0.75x+3−6x=6x−18−6x
−5.25x+3−3=−18−3
−5.25x
/−5.25
=−
21
/−5.25
x=4

Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
The answer is b the median decreased and the median increased
Answer:
Step-by-step explanation:
hello :
the n-ieme term is : An=A1×r^(n-1)
A1 the first term r : the common ratio
in this exercice : A1 =15 r = 1/3 n = 4
A4=15×(1/3)^(4) =15×4^4 =3840
