Which is the solution to the system of equations?

Mathematics
1 answer:
Simora [160]3 years ago
7 0

Answer:

D. (2, -3/4)

Step-by-step explanation:

Using the substitution method:

-5x+4(1/8x-1)=-13

-5x+0.5x-4=-13

-4.5x/4.5=-9/4.5

-x=-2

x=2

You are supposed to replace 2 in the first equation now but as there is no other option with x value of 2 D is the answer.

If continued:

-5(2)+4y=-13

-10+4y=-13

4y=-3

y=-3/4

umka2103 [35]

Answer:

1.000

Step-by-step explanation:

Given that,

Total output from a production system in one day = 900 units

Total labor necessary to produce the 900 units = 900 hours

Productivity refers to the measure of efficiency of the inputs or labors for accomplishing a particular task. Productivity ratio is calculated by dividing the total output of a particular product to the total inputs employed in the production of that product.

Productivity ratio:

= Total output ÷ Total input

= 900 units ÷ 900 hours

= 1.000
