Answer:
x = 3 - 3/10y
Step-by-step explanation:
2/3x + 1/5y = 2
Subtract 1/5y from each side
2/3x + 1/5y -1/5 y= 2-1/5 y
2/3x = 2-1/5y
Multiply by 3/2 to isolate x
3/2 * 2/3x = 3/2 (2-1/5y)
x = 3/2 (2-1/5y)
Distribute the 3/2
x = 3 - 3/10y
Answer: The percent of the estimated time is the actual time is about 14%.

As per given,
Actual time of completing the job = 
Estimated time for completing the job = 
The percentage error is given by:-
The percent of the estimated time is the actual time is about 14%.
A consistent system of equations has at least one solution.
A consistent system is considered to be an independent system if it has a single solution, such as the example we just explored. The two lines have different slopes and intersect at one point in the plane.
A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line. Every point on the line represents a coordinate pair that satisfies the system. Thus, there are an infinite number of solutions.
Another type of system of linear equations is an inconsistent system, which is one in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no points common to both lines; hence, there is no solution to the system.

Answer:
The equation of the blue graph is g(x)=(x-3)^{2} +1g(x)=(x−3)
2
+1 . Below is the explanation
Step-by-step explanation:
Given:
The graph of f(x)=x^{2}x
2
To find:
The equation of the transformed graph g(x).
The red graph f(x) is moved right 3 units and up 1 unit to get g(x).
When graph is moved right 3 units , 3 should be subtracted with x.
When graph is moved up 1 unit, 1 is added at the end.
So, our g(x)=(x-3)^{2} +1(x−3)
2
+1
The equation of the blue graph is g(x)=(x-3)^{2} +1g(x)=(x−3)

Answer:
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The perimeter of a triangle is the sum of the length of their three sides
so
where
a,b,c are the length sides of the triangle
In this problem we have
substitute and solve for the missing length
