Answer:
Step-by-step explanation:
-x - 3y = -1
-3y = x - 1
y = -1/3x + 1/3.....slope here is -1/3 and y int is 1/3
-x - 3y = 2
-3y = x + 2
y = -1/3x - 2/3...slope here is -1/3 and y int is -2/3
these two equations represent parallel lines. Equations that have the same slope and different y intercepts mean the lines are parallel and never cross each others path.
Answer is c indicate a one tailed test
Given:
<span>y = -x2 + 4x + 8
y = 2x2 + 16x + 18
y = -2x2 + 5x + 14
y = -x2 + 17x + 7
y = 2x2 + 11x + 5
y = -2x2 + 6x + 5
Standard formula : y = ax</span>² + bx + c ; -(b/2a) is the x-coordinate of the vertex. Substitute the value of x to find the value of y.
In mixed form, it would be equal to 1 2/7
In short, Your Answer would be Option B
