Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)

5a-2a=7+2+5
a(5-2)=14
a=14/5-2
a=14/4
a=3.5

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!

HELP ASAP PLEASE & SHOW UR WORK!! THANK YOU <3

Answer:

x^2 - 5x = 14

x^2 - 5x-14 = 0

Now, we have to find the multiples of -14 and numbers that add/subtract to -5; this helps to find the factors.

-7+2 = -5

-7*2 = -14

Based on the above info, we can find out my factors; they are:-

(x-7)(x+2)
