If ordered pairs (a, -2) and (4, b) belong to set {(a, b): b=2a-8, find the value of a and b Pl hel :
Will mark as BRAINLIEST :

a = 3   b = 0

Step-by-step explanation:

(a,-2)   b= -2

-2=2a -8

6=2a

3=a

(4,b)   a=4

b=2(4)-8

b=8-8

b=0

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

well what did you do it matters what you did : )
