Determine the domain of the function (f of g)(x) where f(x)=1/ x+3, g(x) =2/x.
Answers
Answer:
(-infinity, -2/3)u(-2/3,0)u(0, infinity)
Step-by-step explanation:
since it is asking for f(g(x)) we plug g into x which looks like:
f(2/x)
now we plug that into the f(x) equation for all of the x's because that is what replaced the x so:
1/(2/x)+3
we look at the denominator so we can pull the 2/x+3 out and set it equal to zero, therefore solving for x
this gives us -2/3
and we get the 0 from g(x) 's denominator
that should be correct and hope this helps!

Answer: One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part A: What is the constant of proportionality shown in the graph?
Answers
Answer:
The constant of proportionality is 3/4
Step-by-step explanation:
Here, we want to write the constant of proportionality in the given graph .
To find the constant of proportionality, we need to find the slope of the line.
We can get the slope by using two of the points on the line.
Mathematically, slope of a line m is;
m = (y2-y1)/(x2-x1)
Let (x1,y1) = (120,90) and (x2,y2) = (400,300)
slope will be ( 300-90)/(400-120) = 210/280 = 3/4

Sharon is planning a holiday for 4 people for 7 days
Here are the costs for the holiday for each person
Travel-£130 hotel-£60 for each day spending money-£350
Work out the total cost of the holiday for 4 people for 7 days
Answers
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600

HELP!!!!
Answers
The equation of a line passes through the point (10,1) and has a slope of
- 0.5 is y = - 0.5x + b.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.
Yes, A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
Now, A line is drawn on the coordinate plane that passes through the point (10, 1) and has a slope of - 0.5.
Therefore, 1 = - 0.5(10) + b.
1 = - 5 + b.
b = 6.
And hence equation of the required line is,
y = - 0.5x + 6.
