In south carolina, the interstates of i-20, i-26 and i-95 approximately form a triangle. a warehouse is to be built that is equidistant from each of the three highways. which construction on the triangle will identify the location for the warehouse ? a) medians b) altitudes c) angle bisectors d) perpendicular bisectors

Solution:

Given Statement About South Carolina:

                            The interstates of I-20, I-26 and I-95 approximately form a triangle.

To Find: A warehouse which  is to be built such that it is equidistant from each of the three highways.

Solution: As we know the point which is equidistant from three vertices is called Circumcenter i.e Circle passing through three vertices of Triangle.The Circumcenter can be found by the point of intersection of Perpendicular Bisectors of triangle.

Option  (D) perpendicular bisectors Satisfies the above Criteria.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
