Answer:
9 3/4 . . . . (for the numbers shown)
Step-by-step explanation:
Each number in the table is the product of the number in the left margin and the number in the top margin:
9 = 3·3
3/4 = 3·1/4
The total of these numbers in the table is the Area value being asked for.
9 + 3/4 = 9 3/4
_____
If there is more to the question that isn't shown, you will need to add those partial products to the total, too. We presume you know how to add fractions and mixed numbers.
Answer: 1200!
Hope this helps :)
we have
Find the roots
Equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore
the answer is
5x = y + 7.4
What is the solution to the system of linear equations? Round to the nearest tenth as needed.
Taking into account the definition of a system of linear equations, the solution to the system of linear equations is x=2.3 and y=4.1
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
In this case, the system of equations to be solved is
There are several methods to solve a system of equations, and it is decided to solve it using the graphical method, which consists of representing the equations on a graph, in the same coordinate system. The intersection of the lines representing the equations is the solution of the system.
In this case, the graph is observed in the attached figure, where it can be seen that the intersection of both lines is the point (x,y)= (2.3,4.1).
Finally, the solution to the system of linear equations is x=2.3 and y=4.1
