Using the elimination method, what is x and y ( please explain, I am still slightly confused)

Mathematics
1 answer:
Blizzard [7]3 years ago

Answer:

(- 4, 1 )

Step-by-step explanation:

Given the 2 equations

x + 3y = - 1 → (1)

- 2x - 3y = 5 → (2)

Adding the 2 equations term by term will eliminate the y- term

- x + 0 = 4

- x = 4 ( multiply both sides by - 1 )

x = - 4

Substitute x = - 4 into either of the 2 equations and solve for y

Substituting into (1)

- 4 + 3y = - 1 ( add 4 to both sides )

3y = 3 ( divide both sides by 3 )

y = 1

solution is (- 4, 1 )

Triangle ptg has side lengths of 18 27 cm and 13 cm what type of triangle is it
diamong [38]
Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.

The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).
