Given equations are

f(x)=2x+24

g(x)=5(0.5)^x

Now we have to complete the table so that we can find for what value of x, both f(x) and g(x) are equal.

values in table are not clear so i will draw a fresh table using values x=-2,-1,0,1,2,3,4

I will show you calculation for x=-2

plug x=-2 into f(x) and g(x)

f(-2)=2(-2)+24=-4+24=20

g(-2)=5(0.5)^{-2}=5(\frac{1}{2})^{-2}=5(\frac{1}{2^{-2}})=5(2^2)=5(4)=20

Similarly you can find other values to complete the table.

From table we see that f(x) and g(x) both are equal to 20 when x=-2

Hence x=-2 is the final answer.

Bethany paid $408.75 for a pair of diamond stud earrings. The sale price was $375. What is the Percent of Sales Tax she paid for
9966 [12]

Answer:

She paid 9% of sales tax

Step-by-step explanation:

The sale price of diamond = $375

Let x be percent of sales tax

So, amount of tax = x\% \times 375 = \frac{x}{100} \times 375 =3.75x

So, Amount including tax = 375+3.75x

We are given that Bethany paid $408.75 for a pair of diamond stud earrings.

So, 375+3.75x=408.75

3.75x=408.75-375

x=\frac{408.75-375}{3.75}

x=9

Hence She paid 9% of sales tax
