When the bases are the same, you can combine the exponents.
x³ [x is where the base is]
For example:
x³ · y² = x³y² You can't simplify this anymore because they have different bases/variables
[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:
x² · x³ =
[when you multiply a variable with an exponent by an exponent, you multiply the exponents together] so:
(x³)²=
There are 4 quadrants in a coordinate plane
- The starting point is in the second quadrant, while the finishing point is in the fourth quadrant.
- The starting point is a reflection of the checkpoint across the y-axis
<u>Part A</u>
The points are given as:
For the starting point, the x-coordinate is negative, while the y-coordinate is positive.
This implies that the starting point is in the second quadrant
For the finishing point, the x-coordinate is positive, while the y-coordinate is negative.
This implies that the finishing point is in the fourth quadrant
<u>Part B</u>
The checking point is given as:
The starting point is given as:
Notice that the y-coordinate of both points are the same, but the x-coordinates are negated.
This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa
