If they are parallel they will have the same slope , m

So in y = mx + c, if there are two equations which both have the same m value they will be parallel.
If the lines are perpendicular they'll have slopes like this: 1/2 to -2/1 - where they flip and a negative gets added.

In the equations: 10x + 5y = -5 , and y = -2x + 6
We can rearrange 10x + 5y = -5 to be in the form y = mx + c
10x + 5y = -5
5y = -5 - 10x
y = -1 - 2x
y = -2x - 1

Since y = -2x - 1 and y = -2x + 6 both have the same slope of -2 they are parallel!

Mr. Vella can build a brick wall in 4 days. His apprentice can build the same wall in 6 days. After working alone for 3 days, Mr
Vitek1552 [10]
Mr. Vella can build the wall in 4 days, however only works on it for 3 days. That means that he has completed 75% of the and is leaving 25% for his apprentice.

We need to figure out how long it takes the apprentice to build 25% of a wall. We know he can build 100% of a wall in 6 days, so dividing 6 days by 4 will give us our answer.

6/4 = 3/2 = 1.5 days

It took the apprentice 1.5 days to finish the wall.

Solve for x given two sides

Solution

x is an angle hence we are gonna use the formula Sin

Sin 0 = opp/hyp

0 represents theta.


Sin 0 = opp/hyp
Sin 0 = 27/33

Put 27/33 in decimal form

= 0.8181

Transpose to make 0 the subject


Sin 0 = 0.8181

0 = Sin-1 0.8181

When adding Sin from one side to another it becomes Sin inverse.

0 = Sin-1 08181

Now we find the answer

0 = Sin-1 0.8181

= 54.89 degrees

Therefore x is equal to 54.9 to the nearest tenth.

If a firm finds that increases in output lead to increases in long-run average total cost, then it must be experiencing ________
Luba_88 [7]

Answer:

The correct option is;

C diseconomies of scale; coordination problems

Step-by-step explanation:

Dis-economies of scale is in effect where the average cost of production of  firm increases as it increases its inputs towards producing more. That is as the production rate increases, the unit cost of production also increases

Increase in the mean cost of production as the production rate increases is an indication of diminishing returns to increasing scale of production

Dis-economies of scale can be caused by Coordination problems

Difficulties in Co-ordination and monitoring . Where there is growth, the monitoring and coordination requirements becomes more complex, there is also the tendency for increased inefficiency and increase in average cost as the firm expands
