Answer:
E=x
or 110= x ( opposite angles of parallelogram are congurent)
E+D = 180 ( angles on st line)
110+D =180
D=70
D=F ( opposite angles of parallelogram are congurent)
so F=70
Answer:
The one in the middle would be the quadratic function. I know this because of how when it gets to 10, it starts to repeat the other two numbers behind it.
Step-by-step explanation:
-14b+28=-10b-30
-4b+28=-30
-4b=-58
b=58/4=29/2
Answer:
2
Step-by-step explanation:
2t = 40 - 2w
t = 40/2 (-2/2)w
t = 20 - w -- rearrange
t = -w + 20
t + w = 15
t = -w + 15
same slope, different y intercepts.....parallel lines, no solutions
