(y -3)^2 = 4y - 12
Expand.
(y-3)(y -3) = 4y - 12
y² - 6y + 9 = 4y - 12
y² - 6y -4y + 9 + 12 = 0
y² - 10y + 21 = 0
Factors are -7y and - 3y
y² - 10y + 21 = 0
y² - 3y - 7y + 21 = 0
y(y - 3) -7(y - 3) = 0
(y - 3)(y - 7) = 0
y-3 = 0 or y - 7 = 0
y = 0 + 3 or y = 0 + 7
y = 3 or 7
Answer:
A and B are parallel to D and C
or
A and D to B and C
basically do a line and expand them if they touch they are not parralelogram but if they don't they are
The answer is -12 bc you take away the 3
Answer:
The slope is -9
and the interpretation is that the percentage that drops on the battery per hour is 9%
Step-by-step explanation:
Generally, the equation of a straight line can be represented by the formula;
y = mx + b
where m is the slope and b is the y-intercept
With respect to the given equation, the slope is -9
What it means is that the percentage that drops per hour on the battery is 9%
