The general form for a pair of linear equations in two variables x and y is
and
----- (1)
----- (2)
Comparing equations 1 and 2 with the general form of equation to write their co-efficient,
Compare the ratio,
If , then the pair of linear equations has exactly one solution.
So, it said to be consistent.
Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

Solve for x

Find the value of y
substitute the value of x in the equation A

so

therefore
The solution is the point (-2,-2)
Answer:
$81
Step-by-step explanation:
9/2 = 4.5
4.5 x 18 = 81
Let me give the significations following
natural numbers :ACA counting numbers the numbers you naturally say when counting.
whole numbers: include all natural numbers zero
Integers: include all whole numbers and their opposites.
Rational: can be written ASA fraction or ratio of two integers also decimals that terminate or repeat
Irrational: can not be written a fraction, decimals, do not terminate or repeat.
