Answer:
the first one
Step-by-step explanation:
the two planes intersect at line YZ, where they meet
tip: planes intersects at a line, just like how lines intersect at a point
hope this helps :)
Put the value of x to the inequality:

Answer:
<h2>The probability is

.</h2>
Step-by-step explanation:
The probability of having high blood pressure is 17%.
We need to find the probability of 2 or fewer have high blood pressure.
Possibility 1: No one have high blood pressure.
The probability is
.
Possibility 2: Only one have high blood pressure.
The probability is
.
Possibility 3: 2 among the 10 have the high blood pressure.
.
Any of the possibilities can happen.
Hence, the required probability is
+
+
.
It looks like your question is incomplete. I believe you also have options to pick which graph is correct. However, I can still give you the information you are looking for.
The slope of the line is -1.2
The Y-intersect is (0, 4)
I have also attached an image of what the graph would look like.
Hope this helps.
Answer:
Divide the 1st equation by 2
a + 2c = 19
Divide the 2nd equation by 3
a + c = 13.5
Subtract the 1st equation and the 2nd equation
c = 5.5
Substituting back into the 2nd equation will give:
a + 5.5 = 13.5
a = 8
