Hello : 
f(x) = (2x-5)/3
<span>f−1(x) = (3x+5)/2 
because : f(x) 0 </span>f−1(x) = x and  f−1(x) 0 f(x) = x
f(x) 0 f−1(x) = f( f−1(x) ) = f ((3x+5)/2) = (2(3x+5)/2  - 5))/3 = 3x /3 =x
same cacul for :  f−1(x) 0 f(x) = x

Calculate the velocity of a car traveling in a straight path due east with a distance of 16 meters in 2 seconds. Question 1 opti
AleksAgata [21]

Answer:

  E 8 m/s

Step-by-step explanation:

The magnitude of the velocity (the speed) is the number of meters divided by the number of seconds. (That's what meters per second means.)

  |V| = (16 m)/(2 s) = (16/2) m/s = 8 m/s

Velocity is a vector quantity, so must include a <em>direction</em> along with the <em>magnitude</em>.

  V = E 8 m/s

Jamie had 4/5 of a spool of twine. He then used 1/2 of a spool of twine to make friendship knots. Over. Explain how you know whe
Ganezh [65]

Answer:

Jamie's claims are correct because 3/10 of the spool twine is left over after using 1/2 of the spool twin for friendship knot

Step-by-step explanation:

Full question: He claims to have 3/10 of the original spool of twine leftover.

First, we compare 3/10 with 4/5 - 1/2

The lowest common multiple for2 and 5 is 10.

To write 4/5 as a fraction with common denominator, multiply numerator and denominator by 2

4/5 = (4×2)/(5×2) = 8/10

To write 1/2 as a fraction with a common denominator, multiply denominator and numerator by5

1/2 =(1×5)/(2×5) = 5/0

So we have :

8/10 - 5/10

Since denominators are equal ,we go ahead and subtract

8/10 - 5/10 = (8-5)/10 = 3/10
