The extended warranty on a garage door is $238. If the warranty costs 35% of the purchase price, how much does the garage door i

-BARSIC- [3]

Answer:

d. $680.

Step-by-step explanation:

Let x be the cost of garage door.

We have been given that the extended warranty on a garage door is $238 and the warranty costs 35% of the purchase price. This means 35% of x equals 238.

We can represent this information in an equation as:

$\frac{35}{100}x=238$

$0.35x=238$

$x=\frac{238}{0.35}$

$x=680$

Therefore, the cost of garage is $680 and option d is the correct choice.

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

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

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

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

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

$\implies \boxed{a=\dfrac12}$

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