Answer:
x = -7/40
, y = -11/20
Step-by-step explanation:
Solve the following system:
{12 x - 2 y = -1 | (equation 1)
4 x + 6 y = -4 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{12 x - 2 y = -1 | (equation 1)
0 x+(20 y)/3 = (-11)/3 | (equation 2)
Multiply equation 2 by 3:
{12 x - 2 y = -1 | (equation 1)
0 x+20 y = -11 | (equation 2)
Divide equation 2 by 20:
{12 x - 2 y = -1 | (equation 1)
0 x+y = (-11)/20 | (equation 2)
Add 2 × (equation 2) to equation 1:
{12 x+0 y = (-21)/10 | (equation 1)
0 x+y = -11/20 | (equation 2)
Divide equation 1 by 12:
{x+0 y = (-7)/40 | (equation 1)
0 x+y = -11/20 | (equation 2)
Collect results:
Answer: {x = -7/40
, y = -11/20
Answer and Explanation:
The Prolog rule expresses that logical implication (:-) describes the relationship between facts.
Prolog expressions are containing truth-functional symbols, which have the same intervention as in predicate calculus.
For example:
English Predicate calculus prolog
and ^ ,
or v ;
By using information, given in the question,
We can make prolog:
Grandfather(X, Y) :-mother(M,Y), father(X,M); father (F, Y), father(X,F)
Prolog (:- ) means define,
Prolog (,) represents a conjunction
And
Prolog (;) represent a disjunction
Answer:
A
Step-by-step explanation:
tan60=opp/adj
tan60=15/x
15tan60=x
25.98=x (when you calculate 15 root 3 it is the same number)
