Rolex worked 40 hours last week. He had 74 deducted from his earnings for taxes. If he had 286 left after the deduction how much does Rolex earn per hour?

Answers

Answer 1
Answer:

Answer:

Rolex earns $9 per hour.

Step-by-step explanation:

Let the number of dollars he earns each hour be x.

To create our equation we need to find the total number of dollars he earned before his deduction which is 40x.

Then we know that he got 74 dollars deducted from his total earnings leaving him with 286 which gives us an equation. 40x + 74 = 286

40x - 74 = 286          (Equation)

40x = 360                  (Add 74 from both sides)

x = 9                           (Divide both sides by 40)

Answers

okay so you have 1750 tickets and 7100 dollars so you gotta do
 7100 divided by 5 wich gives you the amount of adult tickets which is 1420 you then have to take 1420 away from 1750 which leaves you with 330
Label adults ticket x and child's ticket y

How do I find the vertex of the equation y= (x+7)^2 - 5 ?

Answers

Follow through with the function (x+7)²
(x+7)² is the same as (x+7)(x+7).
You get x² + 14x + 49
Plug it back into the equation to get 
y=x² + 14x + 49 - 5, which equals y=x² + 14x + 44
The formula for the x point in the vertex is -b/2a. (a is x² and b is x)
So -14/2 = -7 = x
Plug this into the equation.
y=-7² + 14(-7) + 44
y=49 - 98 + 44
y=-5

(-7, -5)

I apologize for the error beforehand--I typed 49 instead of 44 and ended up with 0 instead of -5. 
If you have an equation in the vertex form y=(x-h)^2+k the vertex is (h,k)

In your case h=-7,k=-5 so the vertex is (-7,-5)

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x +1?A.right 1 unit
B.left 1 unit
C.right 2 units
D.left 2 units

Answers

The vertex of f(x) = x^2 is (0,0)

The vertex of g(x) = x^2 + 2x + 1 = 0 is (-1,0)

Then, translating the f(x) one unit to the left will map (0,0) onto (-1,0).

Answer B: left 1 unit.

Answer: left 1 unit
