Answer:
C and D
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± 
( add 5 to both sides )
3x = ± + 5 ( divide both sides by 3 )
x = 
x = 
→ C
x = 
→ D
When multiplying the same base with exponents, you keep the base the same and then you add the exponents, so for this question you do:
10^3 x 10^6
10^9
The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.
Therefore, since this two lines are parallel, they don't meet and the system has no solution.
The angles are equal (alternate angles in parallel lines)
X + 86 = 80
X = 80 - 86 = -6
