(f+g)(x)=f(x)+g(x)
(f+g)(x)=3x+4+8x+1
(f+g)(x)=11x+5
(f+g)(0)=11(0)+5
(f+g)(0)=0+5
(f+g)(0)=5
Answer:
x>-15
Step-by-step explanation:
if:x+19>4
collect like terms
therefore:
x>4-19
(sign changes when collecting like terms)
+4-19=-15
x>-15
0.47 is the answer. Because it's in the middle of 0.43 and 0.50. I answered this on your last question =p
