Answer:

f(x - 1) = 3x - 8

Step-by-step explanation:

To find f(x - 1) substitute x = x - 1 into f(x), that is

f(x - 1) = 3(x - 1) - 5 = 3x - 3 - 5 = 3x - 8

F(x)=5(x-2) find x if f(x)=-20

Lapatulllka [165]

Answer:

x = -2

Step-by-step explanation:

f(x)= 5(x-2)

since, f(x)= -20

-20 = 5(x-2)

x-2 = -20/5

x = - 4 + 2

x = -2

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

creativ13 [48]

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

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

Jayden sells snow cones for $3.75 each. He started the day with a total of 300 snow cones to sell. If he made a total of $843.75

Leni [432]

Number of cone left is 75 cone

Given that;

Cost of each cone = $3.75 each

Starting number of cone = 300

Total amount earn = $843.75

Find:

Number of cone left

Computation:

Number of cone sale = Total amount earn / Cost of each cone

Number of cone sale = 843.75 / 3.75

Number of cone sale = 225 cone

Number of cone left = Starting number of cone - Number of cone sale

Number of cone left = 300 - 225

Number of cone left = 75 cone
