Answer:

\displaystyle y = -\frac{1}{5} x +6

Step-by-step explanation:

<u>Equation of a LIne</u>

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

y = -\frac{1}{5}+2

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )

Adding 7:

\displaystyle y = -\frac{1}{5} ( x + 5 )+7

Operating:

\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7

\displaystyle y = -\frac{1}{5} x -1+7

\boxed{\displaystyle y = -\frac{1}{5} x +6}

In which of the following cases is productive efficiency not satisfied? Assume we start at a point on the PPF between two produc
DaniilM [7]

Answer:

A. The economy switches to producing less of one product without increasing the production of the other product

Step-by-step explanation:

PPC is the graphical representation of product combinations that an economy can produce, given resources & technology. It is downward sloping because given resources & technology, production of a good can be increased  by decreasing production of other good.

It is based on assumption that resources are efficiently utilised. Points on PPC show resources efficient utilisation, Points under PPC show under utilisation, Points outside PPC are beyond country's productive capacity.

If country produces less of a good without increasing production of other goods, implying wasted resources & production below PPC. This case doesn't satisfy productive efficiency

Other cases : Producing more of a good & less of other is just re allocative movement on the PPC itself. Production point at PPF intersection with either axis implies economy is producing only the good on that axis.

In all the cases except A. satisfy the 'productive efficiency'
