Answer:
- 9x² + 10x + 4
Step-by-step explanation:
Calculate the subtraction as
- 4x² + 2x - 8 - (5x² - 8x - 12 ) ← distribute parenthesis by - 1
= - 4x² + 2x - 8 - 5x² + 8x + 12 ← collect like terms
= - 9x² + 10x + 4
We will put ur equation in y = mx + b form, and the slope will be in the m position.
14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7
y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.
An equation whose variables are polar coordinates is called a polar equation. These equation are characterized by an r as a function an angle. Polar equations can be written in rectangular coordinates by certain relationships. An example of a polar equation would be r = 2sin∅.
