Use the distributive property to expand the expression. −13x − (3y − z) + 5 a) −13x − 3y + z + 5 b) −13x + 3y − z − 5 c) −13x − 3y + z − 5 d) −13x − 3y − z − 5

the answer is a. i put c. like the other person said but it was wrong and it said the right answer was a.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
