7^16/7^12=7^-18/? what is the missing denominator

creativ13 [48]

$\bf \left.\qquad \qquad \right.\textit{negative exponents}\\\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}
\qquad \qquad
\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\qquad \qquad 
a^{{{ n}}}\implies \cfrac{1}{a^{-{{ n}}}}\\\\
-------------------------------\\\\$

$\bf \cfrac{7^{16}}{7^{12}}=\cfrac{7^{-18}}{x}\implies x\cdot 7^{16}=7^{12}\cdot 7^{-18}\implies x\cdot 7^{16}=7^{12-18}
\\\\\\
x\cdot 7^{16}=7^{-6}\implies x=\cfrac{7^{-6}}{7^{16}}\implies x=\cfrac{7^{-6}\cdot 7^{-16}}{1}\implies x=7^{-6-16}
\\\\\\
\boxed{x=7^{-22}}\implies x=\cfrac{1}{7^{22}}$

PLEASE ANSWER ASAP !! Have till 11:59pm

Bond [772]

Step-by-step explanation:

you have the formula and the numbers. just calculate !

cost of membership

y = 100 - 0.02x

for x = 2600

y = 100 - 0.02×2600 = 100 - 52 = $48

the reduction element of the cost of membership is the

"- 0.02x" part.

we want to refuse the membership costs by $41, so

0.02x = 41

x = 41/0.02 = $2,050

the same as b)

just now the membership costs need to be reduced to 0.

so, that means we need to reduce by $100 !

0.02x = 100

x = 100/0.02 = $5,000
