Which of the following sets represents the domain of the function shown? (5 points) {(2, 73, (15, 13), (21,-4), (24, 18)}
O {-4, 2, 7, 13, 15, 18, 21, 24}
{(7, 2), (13, 15), (-4, 21), (18, 24)}
{2, 15, 21, 24}
O {-4, 7, 13, 18)

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

combine all like terms then its just a 2 step equation
