Answer:
- g(x) = root(3, x-1)
- h(x) = root(3, x) -1
Step-by-step explanation:
The graph of f(x) is translated (right, up) = (h, k) to ...
g(x) = f(x -h) +k
___
Graph B is translated right 1 unit, so its function is ...
g(x) = f(x -1) = root(3, x-1)
__
Graph C is translated down 1 unit, so its function is ...
h(x) = f(x) -1 = root(3, x) -1

If one pound is 5.17 dollars
You would have to multiply the two given numbers
Let x be the number of months.
The first plan is 15 dollars sign up fee and 38 dollars per month. So the equation is 38x + 15.
The second plan is 78 dollars as sign up fee and 31 dollars per month. So the equation is 31x + 78.
We need find when x has the same value in both equations, so we do their equality:
38x + 15 = 31x + 78
Let's subtract 15 from both sides
38x + 15 = 31x + 78
38x + 15 - 15 = 31x + 78 - 15
38x = 31x + 63
Now let's subtract 31x from both sides to have the variables on a side and the numbers on side:
38x = 31x + 63
38x - 31x = 31x - 31x + 63
7x = 63
Divide both sides by 7 to have the variable x on a side and its value on the other:
(7x)/7 = 63/7
x = 9
So at month 9, the 2 plans will cost the same.
Let's check our answers, and let y be the cost:
y = 38x + 15 = 38*9 + 15 = 357
y = 31x + 78 = 31*9 + 78 = 357
Our answer has been approved.
Hope this helps! :D
Answer:
y > 24 − 3x
Step-by-step explanation:
Step 1: First, you need to factor out the common term 2.
2 (3x + y) > 48
Step 2: Then, you divide both sides by 2.
Step 3: Next, you have to simplify 
into 24.
3x + y > 24
Step 4: Lastly, subtract 3x from both sides and you're done!
y > 24 − 3x
