Answer:
1,3 2,2 3,4 4,1
Step-by-step explanation:
Xy + yx+ x - 3x - 3y
xy + yx + -2x + 3y
In a rectangle, the diagonals are equal. You need to set the two equal to each other. The line BE would be doubled to equal AC. Then solve:
2(2x-3)=3x+1
4x-6=3x+1
x=7
Now that you have x, you can find AC. Just plug it in.
3(7)+1
21+1
22
There you have it! AC=22
f(x) = 2x + 1
To find the inverse, f^-1(x), of the function:
Put the function as an equation:
y = 2x + 1
Then move x to the left and y to the right;
x = 2y + 1
Then solve for y;
y = x/2 - 1/2
f^-1(x) = y
f^-1(x) = x/2 - 1/2
