I will mark you as brainliest if your answer is good :3
Answers
Answer:
416.50 pesos
Step-by-step explanation:
Given
Represent the bread with b.
Mayonnaise with m
Ham with h
[tex]Amount\ Paid = 1000[/tex]
Required
Determine the change
From the question: a loaf costs 22.50
This is represented as:
[tex]b = 22.50[/tex]
5 loaves will be:
[tex]5*b = 22.50*5[/tex]
[tex]5b = 112.50[/tex]
A bottle of Mayonnaise costs 55.50
This is represented as:
[tex]m = 55.50[/tex]
2 bottles will be:
[tex]2*m = 55.50*2[/tex]
[tex]2m = 111[/tex]
Lastly,
1kg of ham costs 240
This is represented as:
[tex]h =240[/tex]
1.5kg will be:
[tex]1.5*h =240*1.5[/tex]
[tex]1.5h =360[/tex]
The cost of the items is:
[tex]Costs = 5b + 2m + 1.5h[/tex]
This gives:
[tex]Costs = 112.50 + 111 + 360[/tex]
[tex]Costs =583.50[/tex]
Her change is calculated as:
[tex]Change = Amount\ Paid- Cost[/tex]
[tex]Change = 1000 - 583.50[/tex]
[tex]Change = 416.50[/tex]

Perform the indicated operation and state the domain. Let f(x) = 3x^1/3 and g(x) = 2x^1/2 Express as (f+g)(x)
Answers
Answer:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
[tex]x \ge 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^{\frac{1}{3}}[/tex]
[tex]g(x) = 2x^{\frac{1}{2}}[/tex]
Solving (a): (f + g)(x)
In functions:
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
Solving (b): The domain of f(x)
For (f + g)(x) to be defines, the value of x must be greater than or equal to 0.
Hence, the domain is:
[tex]x \ge 0[/tex]
Use the Graph that shows the solution to f(x) = g(x),
f(x) = 1+2x/x
g(x) = 2+x
