A certain species of fish costs $3.99 each. You can spend at most $45. How many of this type of fish can you buy for your aquarium?

Since we can't buy 0.68 of a fish and our number must be less than 13.68, we can buy 13 fish.

Step-by-step explanation:

3.29f ≤ 45

3.29f/3.29 ≤ 45/3.29

f ≤ 13.68

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
