Answer:
Please check attached graph.
Step-by-step explanation:
Graph for the answer choices are missing but still we can solve this problem.
We can create graph of y=-x-3 first
then shade the graph for given inequality.
Comparing y=-x-3 with y=mx+b gives slope m=-1 and y-intercept b=-3
so we graph a point at (0,-3) for y-intercept.
then move the point 1 unit down and 1 unit right to reach point (1,-4)
Now join both points by a solid line because of equal sign of >=
this will give graph of y=-x-3
Now we determine direction of shading using any test point which is not on the line y=-x-3
say (0,0) is test point as it is not on the line y=-x-3
plug the test point into original inequality
which is true so the direction of shading will be in the direction of test point.
Ayy you got it right thank you very much your
Answer:
It is 2
Step-by-step explanation:
y2-y1/x2-x1 you get -4/-2 and when you divide u get 2
The third tree diagram is correct.
The probabilities for the first draw are 3/7 for green and 4/7 for red.
If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).
If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.
To find the range, you need to locate the vertex:
equation for vertex = ax^2 + bx +c
in x^2 + 3, a = 1, b = 0 and c = 3
now vertex form = a(x+d)^2 +e
d = b/2a = 0/2*1 = 0
e = c-b^2/4a = 3-0^2/4*1 = 3
The equation becomes: (x+0)^2 +3.
The range is Y ≥ 3 ( greater than or equal to 3)
