Answer:
A - 2x + 4 + 50 = 10x - 2
Step-by-step explanation:
1.) It is the only equation that makes mathematical sense
2.) The sum of angles ABD and DBC equal angle ABC, and ABC = 10x -2
Note:
x=7 if it is important later on
To calculate the midpoint,here's the formula : ((x1+x2)/2 , (y1+y2)/2)
thus, we have:
((10+(-4))/2 , (6+8)/2)
=(6/2 , 14/2)
=(3,7)
The coordinate for the midpoint is (3,7)
hope it helps!
Answer:
23
Step-by-step explanation:
Well substitute (if there is no sign and their all stocked together, it’s multiplication)
5(3)2 - 5(3)-8
30-7
23
Answer: B: y-coordinate of point A
