How do I solve this 8(c-9)=6(2c-12)-4c

1 answer:

First you are going to distribute and you are going to get 8c-72=12c-72-4c. Next you are going to combine like terms you get 8c-72=8c-72. Then move the Varible to one side and solve for the Varible you should get c=0

Aleks04 [339]

Answer:

about 0.39 (inelastic)

Step-by-step explanation:

Elasticity of supply is the ratio of percentage supply change to a corresponding percentage of price change. Here, that is ...

eos = (410/380 -1)/(0.20) = 0.78947/0.2 ≈ 0.3947

Values below 1 are said to correspond to an <em>inelastic</em> supply, one not very sensitive to price.

Please help me figure out this problem

tiny-mole [99]

Answer:

$f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=x\\\\g(f(x))=g\left(-\dfrac{5}{3}x-7\right)=x$

Step-by-step explanation:

Fill in the given expressions and simplify.

$f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=-\dfrac{5}{3}\left(-\dfrac{3x+21}{5}\right)-7\\\\=\left(-\dfrac{5}{3}\right)\left(-\dfrac{3x}{5}\right)-\left(\dfrac{5}{3}\right)\left(-\dfrac{21}{5}\right)-7\\\\=\dfrac{15x}{15}+\dfrac{5\cdot 21}{3\cdot 5}-7=x+7-7=x$

Going the other way, we have ...

$g(f(x))=\displaystyle -\frac{3\left(-\frac{5}{3}x-7\right)+21}{5}=-\frac{-5x-21+21}{5}=x$
