Answer:
A. 
Step-by-step explanation:
We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.
Since we know that standard form of equation is: 
, where, a, b and c are constants.
Let us multiply both sides of our given equation by 2.
Let us add 6 to both sides of our equation.
Let us subtract x from both sides of our equation.
Multiply both sides of our equation by -1.
Rearranging our equation we will get,
Therefore, the standard form of our given equation is and option A is the correct choice.
Answer:
As you have written
Z Y = 3 X Y,
It means X, Y, Z are collinear points i.e they lie in the same line or line segment.
Locating points X, Y,Z on the line
Two possibilities are possible
1. First Z, then X and then Y on the line or line segment
→ Z X + Y X= Z Y
But Z Y = 3 X Y [ Given]
→ Z X + Y X = 3 X Y
→ Z X = 3 X Y - Y X
→ Z X = 2 X Y ⇒ which is not the result.
2. 2nd Possibility
First Z, then Y and then X on the line or line segment
→ Z X = Z Y + Y X
→ Z X= 3 X Y + Y X [Z Y=3 X Y→(given)]
→ Z X= 4 X Y , Which is the result.

Answer:
241 tons
Step-by-step explanation:
312-170=142
142÷2=71
170+71=241
241+71=312
