(08.03)consider the following set of equations:
equation r: -3y = -3x - 9
equation s: y = x + 3
which of the following best describes the solution to the given set of equations?
no solution
one solution
infinite solutions
two solutions

Equation R: -3y = -3x - 9

Equation S: y = x + 3

Replace y in Equation R with equation S:

-3(x+3) = -3x - 9

Use distributive property:

-3x -9 = -3x -9

Because both sides of the equation are identical x can be any number and they would still be equal.

This means there are Infinite solutions.

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .

answer: 1, 3 and 5 are correct
