Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have
The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
The slope is this and that
3x+y=9.....i
3x-5y=15...ii
subtracting ii from i we get
6y=-6 so y=-1
x=10/3
Answer:
32, 34
Step-by-step explanation:
The answer must be grater than 30 so 30 is not an option the integers in the range are 31, 32, 33, and 34 the only even integers in this set are 32, and 34. Hope this helps. :)
Answer:
Plane Z or plane VTX.
Step-by-step explanation:
From the picture attached,
ST pierces the plane at a point T.
That means line ST is perpendicular to the horizontal plane Z or plane VTX.
Since, S is a point lying on line ST it will not lie on the vertical plane VTX Or plane Z.
Therefore, point S is not contained in the plane Z.
