Answer:
slope is 3
Step-by-step explanation:
Slope = 
change in y = (13-7), (19-13), (25-19), (31-25)
change in y = 6
Change in x = (4-2), (6-4), (8-6), (10-8)
Change in x = 2
Therefore slope = 
Slope = 3

Step-by-step explanation:
-6x+12=-6x-12
-6x+6x=12-12
0=0
Answer:
52°
Step-by-step explanation:
since EB bisects ∠RED, ∠REB = ½× ∠RED.
and the equation could be :
5x-3=½(8x+16)
5x-3=4x+8
5x-4x=8+3
x = 11
so, ∠BED = ∠REB = 5x – 3 = 5(11)-3
= 55-3 = 52°
Answer:
C. y = 21x+90
Step-by-step explanation:
Let x be the number of hours. Each hour costs 21 dollars, so the cost of all the hours would be 21x. Then add a fixed fee of 90 to get C, y = 21x+90
