3x + 2y = 14
x + 2y = 6

Step-by-step explanation:

3x+2y=14

x+2y=6

2x=8

x=4

Substitute 4 x in equation 1

3(4)+2y=14

y=1

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
