Answer:

(m º n)(x) = x -2

Step-by-step explanation:

Here, in the given expression:

m(x)= x+1 and n(x) = x - 3

To find : (m º n)(x)

Now, solving for (m º n)(x)

(m º n)(x) = m (n (x)) = m (x-3)

also, m (x-3) = (x -3) + 1 = x -2

So, (m º n)(x) = x -2

Carlos and Mike earn same amount for 10 hours of part time work

Solution:

Let "x" be the number of hours worked by Carlos and mike

Given that,

Carlos earns $7.25 per hour plus a $10 bonus

Thus, total amount earned by Carlos for "x" hours is given by:

total earned = 7.25(number of hours) + $ 10

total earned = 7.25x + 10 ----- eqn 1

Mike earns $7.75 per hour plus a $5 bonus

Thus, total amount earned by Mike for "x" hours is given by:

total earned = 7.75(number of hours) + $ 5

total earned = 7.75x + 5 ------- eqn 2

To find number of hours, they earn same amount, equate eqn 1 and eqn 2

7.25x + 10 = 7.75x + 5

7.75x - 7.25x = 10 - 5

0.5x = 5

x = 10

Thus for 10 hours, they earn the same amount

If someone could please help me, I want to make sure that the steps are correct.

Your answer would be the last option, c = √(E/m).

We can see this when we rearrange the equation, as:

E = mc²
÷ m
E/m = c²
√
√(E/m) = c

So you got all the steps in rearranging correct :)

I hope this helps!
