The sum is 41.22 because first you turn all of the fractions into decimals and then it’s easier to add them all together all at once.
Answer:
answer B 
Step-by-step explanation:
f(8)=-2*8+5=-11
g(8)=9*8*8+4=580
f(8)+g(8)= -11+580=569
Answer: x < 61.63
Step-by-step explanation:
15.56x - 200 < 758.92
+200 +200
15.56x < 958.92
/15.56 /15.56
x < 61.63
GCF of 32 and 48 = 16
32 - 48
16(2 - 3) <==
Answer:
B
Step-by-step explanation:
Remark
I have to represent f(x) as plus +f(x)
I like to show this situation as +f(g(x)) which I think is much clearer.
+f(x) = 5x - 4
Solution
+f(g(x)) = 5(g(x)) - 4 What has happened is that wherever you see an x on the right you put in g(x).
Now on the right, you put whatever g(x) is equal to.
+f(g(x)) = 5(x^2 - 1) - 4
Remove the brackets.
+f(g(x)) = 5x^2 - 5 - 4
And make x = 0
+f(g(0)) = 5*0 - 5 - 4
+f(g(0)) = - 9
