Answer:

4x - 3y = 36

Step-by-step explanation:

2/3x - 1/2y = 6

Multiply each side by 6 to get rid of the fractions

6* (2/3x - 1/2y) = 6*6

Distribute the 6

12/3 x - 6/2y = 36

4x -3y = 36

Answer:

Once $x$ is opposite to $z$ , they are the same. It is the same for $y$ , equals to 40º.

m∠y = 40º

The ∠x and 40º are supplementary, therefore ∠x = 140º.

∠z = 140º

m∠x = 140º

m∠y = 40º

m∠z = 140º

Considering the explanation from the question 4:

m∠x = 50º

m∠y = 130º

m∠z = 50º

Dada la recta 3x +4y - 12=0 encontrar los puntos de interseccion de la parábola y^2=-9x

Radda [10]

Answer:

(-4 , 6)

Step-by-step explanation:

3x +4y - 12=0

x = 1/3 × (12-4y)

y² = 9 × 1/3 × (12-4y) = 36 -12y

y² + 12y -36 =0

(y -6)² = 0

y = 6

x = -4
