What is 2/9 = 4/x+8 i dont get this fraction solving

Dmitriy789 [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{2}{9} = \frac{4}{x + 8} \\$

$\frac{4}{x + 8} = \frac{2}{9} \\$

Inverse both sides

$\frac{x + 8}{4} = \frac{9}{2} \\$

Multiply sides by 4

$4 \times \frac{x + 8}{4} = 4 \times \frac{9}{2} \\$

$x + 8 = 2 \times 9$

$x + 8 = 18$

Subtract sides 8

$x + 8 - 8 = 18 - 8$

$x = 10$

Done...

The estimated monthly sales of Mona Lisa paint-by-number sets is given by the formula q = 104e−3p2 + p, where q is the demand in

Alona [7]

Answer:

The price elasticity of demand is 0

Step-by-step explanation:

The demand function for monthly sales is given as:

q = 104e^-3p^2 + p

The price elasticity of demand E is obtained by differentiating q with respect to p

E = dq/dp = (-6p + 1) × 104e^-3p^2 +p =

When p = ¥200

E = (-6×200 + 1) × 104e^-3(200)^2 + 200 = -1199 × 104(0) = -1199 × 0 = 0
