If x, y, and z are in proportion, find x if y=16 and z=12

Step-by-step explanation:

Givens

, and are in proportion, which means the must form equal ratios.

Where and

The given ratio is:

If all three numbers are in proportion, we can construct the following expression

Replacing values, we have

Therefore, x is equal to 64/3.

each side has a different length.  

step-by-step explanation:

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
