To find the x-intercept for the equation y = -270x + 810, we need to solve for the value of x when y equals zero.
First, we can rewrite the equation in slope-intercept form, which will allow for easier solving:
y = (-270)x + 810
Next, we can set y equal to 0 to find the value of x when y equals zero:
0 = (-270)x + 810
Simplifying the equation, we get:
0 = -270x + 810
Next, we can add 270x to both sides, resulting in:
270x = 810
Then, we can divide both sides by 270, resulting in:
x = 3.00
Therefore, the x-intercept for the equation is x = 3.00, or 3 minutes. This means that if we pour out flour for 3 minutes, the amount of flour left in the machine will be 0.
