2x - 1 < 10
Add 1 to both sides.
2x < 11
Divide both sides by 2.
x < 11/2
The solution set is all real numbers less than 11/2.
Answer:
x-7 represents x moved 7 units to the left.
Step-by-step explanation:
The translation: (x, y) → (x - 7, y - 4) was performed on a triangle
x is translated into x-7. 7 is subtracted from x . It means x is moved 7 units to the left
y is translated into y-4. 4 is subtracted from y. It means y is moved 4 units down.
So x-7 represents x moved 7 units to the left.
The answer is A. x=4.
Start off by distributing the parentheses into the equation.
4x+2(x+6)=36
4x+2x+12=26
Combine like terms.
4x+2x=6x
6x+12=36
Now solve the equation as normal. Begin by subtracting 12 from both sides to isolate the variable.
6x+12=36
-12 -12
---------------
6x = 24
Divide 6 on both sides to find x.
6x=24
---- -----
6 6
x=4
The solution to the equation is 4.
