how will the circumference of the circle change if it is dilated by a scale factor of 4?

the circumference will be 4 times greater than the original.
the circumference will be 16 times greater than the original.
the circumference will be 1/4 the original.
the circumference will be1/16 the original.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
