Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation:
A second linear equation is given by the table:
Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:
Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)
Answer:
- See below
Step-by-step explanation:
<h3>#7</h3>- 5⁵(16²5³)³ = 5⁵(2⁴)³(5³)³ = 5⁵2¹²5⁹ = 5¹⁴2¹²
- (8⁴5³/8⁵)² = (5³/8)² = (5³)²/(2³)² = 5⁶ / 2⁶
- (5⁸3⁷/5⁴)¹⁰ = (5⁴3⁷)¹⁰ = (5⁴)¹⁰(3⁷)¹⁰ = 5⁴⁰3⁷⁰
