Mathematics

Hi, here is the solution...

We need to find the value of f(-2).

The value of x = -2 comes under the second function f(x) = 4x, where -3≤x≤-1.

To find the value of f(-2), plug in x = -2 in f(x) = 4x

f(-2) = 4 (-2)

f(-2) = -8.

The answer is -8.


Thank you :)

Let other be x

Using angle sum property

\\ \rm\Rrightarrow x+97=180

\\ \rm\Rrightarrow x=180-97

\\ \rm\Rrightarrow x=83°

I NEED THIS ANSWER TODAY PLEASE!!!! A hotel manager found that his gross receipts for the day, including a 3% sales tax, were $2
Mekhanik [1.2K]
<h3>Answer: 80.58 dollars</h3>

==================================================

Work Shown:

x = amount of money collected before tax is added

3% = 3/100 = 0.03

3% of x = 0.03x = amount of tax

x + 0.03x = adding on tax to original amount

1.03x = amount after tax is added

1.03x = 2766.58

x = 2766.58/1.03

x = 2686 is the amount of money before the 3% sales tax is added

0.03x = 0.03*2686 = 80.58 is the amount of sales tax collected

As a check,

2686+80.58 = 2766.58

which confirms our answer
