Which equation represents a line that passes through (5, 1) and has a slope of 1/2?
lesya692 [45]

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = \frac{1}{2} and (a, b) = (5, 1), so

y - 1 = \frac{1}{2}(x - 5)

Find the solution of this system of equations. Separate the x- and y-values with a comma. x - 4y = 12 and x - y = 0
Elenna [48]
Use elimination and subtitution method to solve the problem.
First, eliminate x and you'll find the value of y
x - 4y = 12
x -  y  = 0
--------------- - (substract)
     -3y = 12
        y = 12/-3
        y = -4

Second, subtitute -4 as y and you'll find the value of x
x - y = 0
x- (-4) = 0
x + 4 = 0
x = -4

The solution
x,y = -4,-4

As the cost of the equipment is increasing the fixed efficiency and idle capacity variance would be unfavorable resulting in an  unfavorable fixed overhead flexible minus budget variance.

The expenses of the machinery are the fixed indirect costs which result in fixed overhead variances. Since it is related to the working of the machinery it would result in efficiency and idle capacity variances that in turn would give unfavorable fixed overhead of the flexible minus budget variance.
