Let's say the point is (x,y) and it lies in 1st quadrant with both x and y as positive ,
Now let's say that the point is rotated by 270 degrees counter clockwise
It means The point will shift to the 4th quadrant , and we know that in 4th quadrant , the x is positive and y is negative ,
Also , as it is rotated by 270 degrees , the x and y values will interchange
SO there are two steps
1) Change the sign of x
2) Interchange the x and y values , i.e swap , x with y and y with x
Answer:
s to the power of 3
Step-by-step explanation:
Answer:
x = age of coin 1
7 + 2*x = age of coin 2.
Step-by-step explanation:
We have two coins, let's denote the ages as:
x = age of coin 1
y = age of coin 2.
Then, the statement is:
"one coin is seven more than twice as old as another."
let's suppose that this refers to y, then:
y = 7 + 2*x
So now we can represent the ages of both coins with only one variable, x.
x = age of coin 1
7 + 2*x = age of coin 2.
