For f(x)=2x+1 and g(x)=x^2-7 find (og)(2)

Step-by-step explanation:

g(2) = 2^2 - 7 = 4 - 7 = -3

f(-3)= 2(-3) + 1 = -6 + 1 = -5

the 4th choice is the correct one

step-by-step explanation:

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
