Which line represents the direct variation equation y = 1/2x?

Mathematics

Verdich [7]3 years ago

Answer:

C.

Step-by-step explanation:

y = 1/ x must pass through the origin because when x = 0, y = 0.

So its either B or C.

A positive slope rises to the right ( 1/2  is positive), so its C.

You can also see that the slope of C is 1/2 because it passes through the points (0.0) and (2, 1).

Answer:

Line C

Step-by-step explanation:

the slope is 1/2 so change in y/ change in x which means 1 is the y and 2 is the x.

the y-intercept is 0.

So up 1 right 2 starting from the origin (0,0)

The cost to produce x units of wire is C= 55x + 450, while the revenue is R= 80x. Find all intervals where the product will at l
jek_recluse [69]

Answer:

The interval where the product will at least break even is given by x ≥ 10.

In interval notation the interval will be denoted by [10, ∞).

Step-by-step explanation:

i) the cost to produce x units of wire is C = 55x + 450

ii) the Revenue is R = 80x

iii) therefore the product will at least break even when

    the cost, C   = the Revenue, R.

 therefore 55x + 450 = 80x   \Rightarrow  (80 - 35)x  = 45x = 450    ∴x = 450 / 45 = 10.

iv) The interval where the product will at least break even is given by x ≥

    10.

   In interval notation the interval will be denoted by [10, ∞).
