,  15\%  of the usual price is the savings .

<u>Step-by-step explanation:</u>

Here we have , At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. We need to find What percentage of the usual price is the savings . Let's find out:

Initially we have cost as $80 , in sale it is $12 less i.e.

⇒ 80-12

⇒ 68

So , percentage of the usual price is the savings :

⇒ \frac{80-68}{80}(100)

⇒ \frac{12}{80}(100)

⇒ \frac{3(4)}{20(4)}(100)

⇒ \frac{3}{20}(100)

⇒ 3(5)

⇒ 15\%

Therefore ,  15\%  of the usual price is the savings .

Given function of f(x) = 2x - 1 and fg(x) = 10x + 3, find the function of g(x)​
denis-greek [22]

Answer:

The function of g(x) = 5x + 2

Step-by-step explanation:

Let us use the composite function to solve the question

∵ f(x) = 2x - 1

∵ f(g(x)) = 10x + 3

→ f(g(x)) means substitute x in f(x) by g(x)

∴ f(g(x)) = 2[g(x)] - 1

→ Equate the two right sides of f(g(x))

∴ 2[g(x)] - 1 = 10x + 3

→ Add 1 to both sides

∴ 2[g(x)] - 1 + 1 = 10x + 3 + 1

∴ 2[g(x)] = 10x + 4

→ Divide each term into both sides by 2

∵ \frac{2[g(x)]}{2} = \frac{10x}{2} + \frac{4}{2}

∴ g(x) = 5x + 2

∴ The function of g(x) = 5x + 2
