Answer:
Step-by-step explanation:
We are given:
Factor:
Difference of Two Squares:
Zero Product Property:
Solve:
Take the square root. Since we are taking an even-root, it requires plus/minus:
The answer to your equation is the same equation. 81x^2+18x+1. Why? Because there are no like terms. BUT THIS IS THE CORRECT ANSWER
If we factor the equation: 81x^2+18+1.... It will be:
(9x+1)(9x+1) - This will be the answer if we factor it.

Answer:
The required expression is:
Please check the attached graph too.
Step-by-step explanation:
The slope-intercept form of the linear or line function
where
- m is the rate of change or slope
In our case,
The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.
Thus, the y-intercept b = 3
It is stated that the cost of per kilometer distance = $0.5
Thus, the rate of change or slope m = 0.5
As y represents the cost and x represents the number of kilometers.
so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function
y = mx+b
y = 0.5x + 3
Thus, the required expression is:
Please check the attached graph too.
Step-by-step explanation:
-4x+6<2x
add 4x to both sides
-4x+4x+6<2x+4x
0+6<6x
divide both sides by 6
6/6<6/6x
1<x
all values for the solution to the inequality are greater than 1
