Place the steps for finding f -1(x) f(x)=2x+5

olya-2409 [2.1K]

Answer:

$f^{-1}(x) = \frac{x-5}{2}$

Step-by-step explanation:

$f(x) = 2x+5$

Step 1) Replace y = f(x)

$y = 2x+5$

Step 2) Exchange x and y

$x =2y+5$

Step 3) Solve for y

$x =2y+5$

Subtracting both sides by -5

$x - 5= 2y$

$2y = x-5$

Dividing both sides by 2

$y = \frac{x-5}{2}$

Step 4) Replace $y = f^{-1}(x)$

$f^{-1}(x) = \frac{x-5}{2}$

What is the effective rate of a $30,000 non-interest-bearing simple discount 5%, 60-day note?

balu736 [363]

30000 due at the end of 60 years
I'll assume that the number of days in year is 360
I=30,000×0.05×(60÷360)=250

Cash in hand at the beginning of 60 days is
30,000−250=29,750

The effective rate is
R=I÷pt
R=250÷(29,750×(60÷360))
R=0.0504×100
R=5.04%

Xiao’s teacher asked him to rewrite the sum 60+90 as a product of GCF of two numbers and A sum . xiao wrote 3(20+30.what mistake

maks197457 [2]

The first thing we must do for this case is find the factors of each of the numbers.

We have then:

60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Therefore the GCF is given by:

$GFC = 30$
