Use substitution.
anywhere you see "a" , than you would plug in b + 2 in for it so....
(b - (b + 2)^4
now take the negative sign and distribute it "+"
so b - b is 0, than 0 - (-2) is -2.
so what is (-2)^4 ????? it would become positive 16
Only A is a function because it is the only one with just one input for every output. Function B has 4 in the x position twice.
Get the unknown by itself: Divide both sides by -10: X≤10. Since you divided by a negative number the less than sign became a greater than sign. I hope that makes sense :)
Answer : i believe 100 X is 13 Z is 12
Step-by-step explanation:
sorry if im wrong
The answer would have to be -4
