6x=7-4y
Move 'y' to one side
6x-7=-4y
6x-7
------- = y
-4
Let P be the last point in the triangle you have drawn from AB.. It is isosceles and rectangle hence AB^2=2BP^2 hence AP=BP=sqrt(2).
Let Q be the last point in the triangle you have drawn from CD. By the same reasoning, CQ=DQ=sqrt(2)
What is more, AD=AP+PQ+QD=2sqrt(2)+1
Answer:
1+3
Step-by-step explanation:
Since there is two minus signs, you can turn the minus sign to addition and turn the negative sign positive. Subtracting a negative is the same as adding a positive.
Answer:
all real x
Step-by-step explanation:
-3(x-1) > -3x - 2
Distribute
-3x +3> -3x -2
Add 3x to each side
-3x +3 +3x > -3x+3x - 2
3 > -2
This is always true so the inequality is true for all x
Answer:
x=7
Step-by-step explanation:
