The price P of a good and the quality Q of a good are linked.
Irina-Kira [14]

the equilibrium point, is when Demand = Supply, namely, when the amount of "Q"uantity demanded by customers is the same as the Quantity supplied by vendors.

That occurs when both of these equations are equal to each other.

let's do away with the denominators, by multiplying both sides by the LCD of all fractions, in this case, 12.


\bf \stackrel{\textit{Supply}}{-\cfrac{3}{4}Q+35}~~=~~\stackrel{\textit{Demand}}{\cfrac{2}{3}Q+1}\implies \stackrel{\textit{multiplying by 12}}{12\left( -\cfrac{3}{4}Q+35 \right)=12\left( \cfrac{2}{3}Q+1 \right)} \\\\\\ -9Q+420=8Q+12\implies 408=17Q\implies \cfrac{408}{17}=Q\implies \boxed{24=Q} \\\\\\ \stackrel{\textit{using the found Q in the Demand equation}}{P=\cfrac{2}{3}(24)+1}\implies P=16+1\implies \boxed{P=17} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{Equilibrium}{(24,17)}~\hfill

Surface Area Of Cylinders <br><br> Please show work<br><br> It would make my year if you helped
jeka94

Answer:

1st cylinder: 3541.9 square mm

2nd cylinder: 439.6 square cm

Step-by-step explanation:

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(12)^{2} + 2(3.14)(12)(35)\\s = 6.28(144) + 6.28(420)\\s = 904.32 + 2637.6\\s = 3541.92\\s = 3541.9

Second cylinder.

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(7)^{2} + 2(3.14)(7)(3)\\s = 6.28(49) + 6.28(21)\\s = 307.72 + 131.88\\s = 439.6
