Answer:
It is the top left one
Step-by-step explanation:
Step-by-step explanation:
Line A : x + y = 2
The most likely equation for line B so that the set of equation has no solution is:
x + y = 4
====
x + y = 2
x = 2 - y
2-y + y = 4
0 = 4 - 2
0 ≠ 2
there is no value for x nor y. so, no solution.
The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation.:)
Answer:
The number of watches must he repair to have the lowest cost is 54.
Step-by-step explanation:
The cost of operating Bob's shop is given by
Differentiate the given function with respect to x.
... (1)
Equate C'(x) equal to 0, to find the critical point.
Divide both sides by 4.
Differentiate C'(x) with respect to x.
C''(x)>0, it means the cost of operating is minimum at x=54.
Therefore the number of watches must he repair to have the lowest cost is 54.
Ok so if the parenth function is y=x^2
to move it up c units, add c to whole function
to move it right c units, minus c from every x
looks like we have
y=(x-6)^2-5
add -5 to whole funciton
minus 6 from every x
means that it moved 5 units down and 6 to the right from original function if parenth is y=x^2
