If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step

LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

$f(x) =3x-5$

To find f(3), replace every x with 3:

$f(3) =3(3)-5\\f(3) =9-5\\f(3) =4$

Therefore, f(3)=4.

$f(x) =3x-5$

To find f(-7), replace every x with -7:

$f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26$

Therefore, f(-7)=-26.

I hope this helps!

frez [133]

Answer: $2\dfrac13\text{ miles per hour}$

Step-by-step explanation:

Given: Distance traveled by Smith = $\dfrac23$ mile.

Time taken = $\dfrac27$ hour

Unit rate in miles per hour = ( Distance traveled by Smith) ÷ (Time taken)

$=\dfrac23\div\dfrac27$

$\\\\=\dfrac23\times\dfrac72\\\\=\dfrac73\\\\=2\dfrac13\text{ miles per hour}$

Unit rate = $2\dfrac13\text{ miles per hour}$
