connor. counted twice as many zebras as clowns in the carnival.he counted a total of 36clowns and zebras in all.how many zebras
olga nikolaevna [1]
36 clowns and zebras..
if there are twice as many zebras as clowns then divide the amount by 2
36/2 = 18 so..
now there are 18 zebras and 18 clowns but we want twice as many zebras..

so by process of elimination we can figure out that
there are 24 zebras and 12 clowns which = 36 
the answer is 24 zebras Connor counted

The graph of which function is decreasing over the interval (–4, ∞)? f(x) = (x + 4)2 + 4 f(x) = –(x + 4)2 + 4 f(x) = (x – 4)2 –
kow [346]

Your post would be clearer if you'd please put each function on its own line:


f(x) = (x + 4)2 + 4

f(x) = –(x + 4)2 + 4

f(x) = (x – 4)2 – 4

f(x) = –(x – 4)2 – 4


Also, use "^2" to denote "squaring." x2 has no meaning.


f(x) = (x + 4)^2 + 4 has a parabolic graph with vertex (-4,4). It increases steadily once x is greater than -4. Reject this choice.


f(x) = –(x + 4)^2 + 4 has a parab. graph with vertex (-4,4) also. It decreases steadily once x is greaster than -4. This is the answer.


Analyze the other 2 possible answers in the same way, please.
