One of the zookeepers solved to find bernard’s speed when he is healthy using the equation:

x – 41.5 = 13.5.

the other zookeeper said that to solve for bernard’s speed when he is healthy, they must use the equation: 41.5 + 13.5 = x.

which zookeeper is correct? explain.

Both the zoo-keepers are correct.

Step-by-step explanation:

The first zoo keeper uses the equation:

x - 41.5 = 13.5

⇒ x = 13.5 + 14. 5 = 55

Now, the second zoo- keeper uses the equation:

41.5 + 13.5 = x

⇒ x = 55

Both use x = 55.

answer: i don't understand it

step-by-step explanation: sorry

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
