ANSWER: Company C

EXPLANATION:

1) Find the least common multiple of 6, 10 and 12. This would be 60 because:

6 x 10 = 60

10 x 6 = 60

12 x 5 = 60

2) Now you can figure out how much money each company gives for every $60 worth of gift wrap by multiplying the amount they gave in the paragraph by the same as what you did in the calculations above.

<u>Company A</u>

$1 x 10 = $10 for every $60 worth of gift wrap sold

<u>Company B</u>

$2 x 6 = $12 for every $60 worth of gift wrap sold

<u>Company C </u>

$3 x 5 = $15 for every $60 worth of gift wrap sold

ARGUMENT

Company C should be selected because they give the most money per dollar ($15 per $60 worth of gift wrap sold).

F(x)=ax+b/2 then f^-1 (x-1) =2x-5/2 find a and b​
krok68 [10]

From the given inverse function, we have

f^{-1}(x-1) = 2x - \dfrac52 \\\\ \implies f^{-1}(x) = f^{-1}((x+1)-1) = 2(x+1) - \dfrac52 = 2x-\dfrac12

By definition of inverse function,

f\left(f^{-1}(x)\right) = x

so that

f\left(2x-\dfrac12\right) = x

a\left(2x-\dfrac12\right) + \dfrac b2 = x

2ax - \dfrac a2 + \dfrac b2 = x

\implies\begin{cases}2a=1 \\\\ -\dfrac a2+\dfrac b2 = 0\end{cases}

\implies \boxed{a=\dfrac12}

\implies \dfrac b2 = \dfrac a2 \implies \boxed{b=\dfrac12}

The ratio of the units digit to the tens digit in a two-digit number is one-half. the tens digit is two more than the units digi
vodomira [7]
Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2).  Write a formula for y in terms of x.

The tens digit is 2 more than the units digit.  Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.
