Mathematics

Given equation is y=3x+3 and \frac{1}{3}y=x+1

Let's simplify the 2nd equation \frac{1}{3}y=x+1 before we can start graph so that calculation will be easy

\frac{1}{3}y=x+1

multiply both sides by 3 to cancel out fractions

3*\frac{1}{3}y=3*x+3*1

y=3x+3

which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.

y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.

1) If 2x + 3y = 12 and xy = 6, find the value of 4x2 +9y2.​
d1i1m1o1n [39]

Answer:

72

Step-by-step explanation:

Given that 2x + 3y = 12 , then

(2x + 3y)² = 12² = 144 ← distribute left side using FOIL

4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )

4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72
