Answer:
−4+5−2
Step-by-step explanation:
Just combine the like terms which are 3y and 2y, you add and get 5y and everything else stays the same
The anser is that what i think
Answer:
X = $75
Step-by-step explanation:
X=total cost
x* (1/3) =$25
multiply by 3 on both sides
x=$75
Answer:
(-2,21)
Step-by-step explanation:
2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.
8 days ago means that x-coordinate -8 represents this day. Count 8 units to the left and find that when x = -8, y = 24 minutes.
9 days ago means that x-coordinate -9 represents this day. Count 9 units to the left and find that when x = -9, y = 18 minutes.
Find halfway commute time between points (-8,24) and (-9,18):

then coordinates that Paulo should graph are
(-2, 21)
(-2 means 2 days ago, 21 is the halfway)
Y-8= 3(x+2)
Y-8= 3x + 6
+8. +8
Y= 3x +14
