Answer:
x = 3
Step-by-step explanation:
First, simplify by subtracting 2x from 6x:
6x - 2x + 8 = 20
4x + 8 = 20
Then, solve for x:
4x + 8 = 20
4x = 12
x = 3
So, the answer is x = 3
Answer:
P < -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Add 4 to both sides.
Therefore, the answer is P < -1! (Also, the graphed solution is below.)
Answer:
f(x)=3x−1
2
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation:
(-∞,∞)
Set-Builder Notation:
{x|x∈R}
The range is the set of all valid
y
values. Use the graph to find the range.
Interval Notation:
(−∞,∞)
Set-Builder Notation:
{y|y∈R}
Determine the domain and range.
Domain:
(−∞,∞),{x|∈R}
Range:
(−∞,∞),{y|y∈R}
x / 3 ≤ -6
---Multiply both sides by 3 to cancel out the denominator on the left side
x ≤ -18
Hope this helps!
Simplify:
3(x - 1) = 8x -3
Expand:
3x - 3 = 8x - 3
Cancel -3:
3x = 8x
Move all terms to one side:
3x - 8x = 0
Simplify 3x - 8 to -5x
-5x = 0
Divide both sides by -5:
x = 0
