Answer: Hello mate!
we know that p(x,y) means "Student x has taken class y"
and the used symbols are:
∃: this means "existence", you use this symbol to say that there exists at least one object that makes true the sentence.
∀: this means "for all", you use this symbol to say that the sentence is true for all the elements, then:
a) ∃x∃yP (x, y)
"exist at least one student x, that took at least one class y"
b) ∃x∀yP (x, y)
"exist at least one student x, that took all the classes y"
c) ∀x∃yP (x, y)
"every student x, took at least one class y"
d) ∃y∀xP (x, y)
"exist at least one class y, that has been taken by all the students x"
e) ∀y∃xP (x, y)
"for every class y, there is at least one student x that took the class"
f) ∀x∀yP (x, y)
"all the students x took all the classes y"
Two of the side lengths and one of the angles of both of the triangles. Hope this helps!
The Solution:
Given the equation of a line:
We are required to find the equation of a line that is perpendicular to the given line and passes through the point (-12,-1).
Step 1:
Determine the slope of 6x-y-4=0.
The coefficient x, after making y the subject of the formula, is the slope of the given line. That is:
Step 2:
Find the slope of the required line:
Since the two lines are perpendicular, the slope is:
Step 3:
Find the equation of the line that passes through point (-12,-1)
By formula,
In this case,
Substituting these values in the formula, we get the required equation is:
Cross multiplying, we get
Therefore, the correct answer is:
