<u>The concept:</u>
We are given the equation:
Which can be simplified as:
Since any number to the power '0' is 1
x² - x must be equal to 0 for the given equation to be true
<u></u>
<u>Solving for x:</u>
x² - x = 0
x(x-1) = 0
now, we can divide both sides by either x OR x-1
So we will see what we get for either choice:
x = 0/(x-1) x-1 = 0/x
x = 0 x = 1
Hence, the value of x is either 0 or 1
The equation y = 7x -3 is not proportional
The given equation is:
y = 7x - 3
For an equation to be proportional, the y-intercept must be (0, 0)
Calculate the y-intercept of y = 7x - 3
Substitute x = 0 into the equation y = 7x - 3 to know the corresponding value of y
y = 7(0) - 3
y = -3
Therefore, the y-intercept of the equation y = 7x - 3 is (0, -3).
Since the y-intercept is not equal to (0, 0), the equation y = 7x - 3 is not proportional
