what is the sum of the rational expressions below? x/x-2 + 7x/x+5
a. 8x/2x+3
b. 8x/x^2+3x-10
c. 8x^2-9x/x^2+3x-10
d. 8x^2-9x/2x+3
Final answer:
The sum of the rational expressions is found by obtaining a common denominator, combining the numerators, and simplifying the resulting expression. The correct answer is [tex](8x^2-9x)/(x^2+3x-10).[/tex]
Explanation:
The sum of the rational expressions [tex]x/(x-2) + 7x/(x+5)[/tex] requires finding a common denominator before the sum can be calculated.
The common denominator for these two fractions is the product of the individual denominators (x-2) and (x+5), which is [tex]x^2+3x-10.[/tex]
Once we have a common denominator, we can combine the numerators and simplify the expression as follows:
Multiply the first term by (x+5)/(x+5) and the second term by (x-2)/(x-2) to create a common denominator.
Combine the numerators: [tex]x*(x+5) + 7x*(x-2)[/tex]
[tex]= x^2+5x + 7x^2-14x[/tex]
[tex]= 8x^2-9x.[/tex]
Place the combined numerator over the common denominator: [tex](8x2-9x)/(x^2+3x-10).[/tex]
Therefore, the correct sum of the given rational expressions is option c. [tex](8x2-9x)/(x^2+3x-10).[/tex]
How many solutions are there to the system of equations graphed below if the lines are parallel
Answer:
Zero
C is the correct option.
Step-by-step explanation:
In the given graph, the given lines are parallel to each other and hence never intersect.
Now, we know that the intersection point (s) of two curves gives us the solution.
Here the lines are parallel to each other and hence do not intersect each other.
Thus, there would not be any intersection point.
Hence, the system of equations has no solution.
C is the correct option.

The x-values in the table for f(x) were multiplied by -1 to create the table for g(x). What is the relationship between the graphs of the two function.
As g(x) is a function that is multiplied by - 1 with f(x) D. They are reflections of each other over x = y.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, g(x) is a function that is multiplied by - 1 with f(x).
∴ f(x) = - g(x).
So, They are reflections of each other over x = y.

Find the orbital period (in years) of an asteroid whose average distance from the sun is 10 au.
The orbital period (in years) of an asteroid whose average distance from the sun is 10 AU is 212314723 years.
What is Orbital period ?
Orbital period of a body is the the time taken by a body to cover one circular path around the central object under whose influence it is following circular path.
Given is a asteroid moving around the sun.
Mean distance from the Sun [x] = 10 AU = 1.496 x 10¹² m.
Assume that the time period of the asteroid is T.
The formula to calculate the orbital period around the sun is -
T²/ R³ = 4π²/GM[s]
Where -
R is the mean distance from sun.
G is the universal Gravitation constant.
M[s] is the mass of Sun.
Substituting the values, we get -
T² = (1.496 x 10¹² x 4 x 3.14 x 3.14)/(6.673 x 10⁻¹¹ x 1.98 x 10³⁰)
T² = (59 x 10¹²)/(13.2 x 10⁻¹⁹)
T² = 4.45 x 10 x 10³⁰
T² = 44.5 x 10³⁰
T = √44.5 x √10³⁰
T = 6.7 x 10¹⁵ seconds
In years, the time period will be -
T = 212314723 years (approx.)
Therefore, the orbital period (in years) of an asteroid whose average distance from the sun is 10 AU is 212314723 years.

what is the mad for 9,7,6,2,2,1
Answer:
9 + 7 + 6 + 2 + 2 + 1 = 27 ÷ 6 = 4.5
4.5 - 9 = 4.5
4.5 - 7 = 2.5
4.5 - 6 = 1.5
4.5 - 2 = 2.5
4.5 - 2 = 2.5
4.5 - 1 = 3.5
4.5 + 2.5 + 1.5 + 2.5 + 2.5 + 3.5 = 17 ÷ 6 = 2.83 or 2.8
so our MAD is 2.83 or 2.8!
Messi kicks a soccer ball from a position that is 3 meters from a sideline and 4 meters from a goal line. the ball lands at a position that is somwhere ... After watching the replay, the ratio between the distance of Messi and the ball is 3/2 meters to the distance between Suarez and the ball.
The actual answer to this problem is (4.8,7.6)
Using the internal division formula the coordinates of the ball are (4.8,7.6).
Let us assume the x-axis as the goal line and the y-axis as the sideline
So, coordinates Messi≡(3,4)
Similarly, coordinates Suarez≡(6,10)
Let us suppose the ball is somewhere in between Messi and Suarez
Suppose coordinates of the ball ≡(a,b)
Since the ratio between the distance between Messi and the ball to the distance between Suarez and the ball is 3/2.
This means ball is internally dividing Messi and Suarez in 3:2
So, applying the internal division formula for a straight line.
What is the internal division formula for a straight line?If a point (a,b) is internally dividing a line segment with coordinates of endpoints as (x₁,y₁) and (x₂,y₂) in the ratio m:n then
[tex]a= \frac{m_{1}x_2+m_2x_1 }{m+n}[/tex]
[tex]a= \frac{m_{1}y_2+m_2y_1 }{m+n}[/tex]
So, [tex]a = \frac{3*6 + 2*3}{3+2}[/tex]
[tex]a=4.8[/tex]
[tex]b= \frac{3*10+2*4}{3+2}[/tex]
[tex]b=7.6[/tex]
So, the coordinates of the ball≡(4.8,7.6)
Therefore, Using the internal division formula the coordinates of the ball are (4.8,7.6).

Andrew is given a weekly allowance of $17.50 he uses $4.50 for lunch on Monday what amount at the most can he spend each day if he wants to spend the same amount each of the remaining 4 days write an inequality and solve
The inequality representing Andrew's spending limit is d <= $3.25, where d is the daily spending amount for the remainder of the week. Solving this, Andrew can spend at most $3.25 per day for the next 4 days.
Andrew received a weekly allowance of $17.50. He spent $4.50 on lunch on Monday. The question is how much at most can he spend each day for the remaining 4 days if he spends the same amount each day. To answer this, we subtract the amount spent on Monday from the total weekly allowance to find the remaining balance. Then, we divide this remaining balance by the number of days left in the week to find the daily spending limit:
Total allowance = $17.50
Spent on Monday = $4.50
Remaining balance = Total allowance - Spent on Monday
= $17.50 - $4.50
= $13.00
Days left in the week = 4
Daily spending limit = Remaining balance \/ Days left
= $13.00 / 4
= $3.25
