Answer:
just plug in
g(x)=7x
g(-7)=7*(-7)
7*(-7)=-49
Step-by-step explanation:
4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
Absolute value because for any number given the y or answer will be no less than 0 it will.always be positive
