Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1
So a tangent of the perpendicular line is "-(1/5)".
Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).
On the other hand, this equation pass r(1, 3), so
3 = -(1/5) times 1 + a
∴ a=16 / 5
Therefore, y=-(1/5)x+16 /5 is answer.
By the way, I'm Japanese so if you find some mistakes in my English, please let me know.
Answer:
Triangle ABC has been translated 1 unit to the left and 4 units up
Step-by-step explanation:
Choose one of the points, for example B, and follow the units to B prime and see how many units vertically and horizontally the point as been translated.
The answer would be B because difference means subtracting so the answer would be x-6
Answer:
The answer is 
Step-by-step explanation:
Let,
Amount of alloy with 30% silver = x g
Given,
Amount of alloy with 10% silver = 200 g
So, Total Amount of alloy with 24% silver = (x+200) g
Now,
