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
4(x - 3) - r + 2x = 5(3x - 7) - 9x
4x - 12 - r + 2x = 15x - 35 - 9x
6x - 12 - r = 6x - 35
6x - 6x - 12 + 35 = r
23 = r <==
with ur answer : -r = -23....u would multiply both sides by -1 to make r positive....resulting in : r = 23....so u basically got the same thing I did...just didn't quite finish
Answer:
the answer is 77
Step-by-step explanation:
A measures 32 and B measures 109 so you subtract 109 and 32 and your answer will be 77
15x^2 + 12x +10x + 8= 0 reduced 15x^2 +22x+ 8 = 0
