To do this problem, we must first distribute the 13 and 14 into the parenthesis.
<span>13(9−6m)+14(12m−8)
117 - 78m + 168m - 112
To combine like terms, we can add/subtract terms that have an "m" together and then we can add/subtract terms that do not have "m" together.
117 - 112 = 5
and
168m - 78m = 90m
So our final sum is 5 + 90m</span>
729-243=486
486×3=1458
1458+729=2187(x=7)
1458×3=4374
4374+2187=6561(x=8)
4374×3=13122(average rate of change for interval 8 to 9)
13122+6561=19683(x=9)
Ans: B
Answer:
Step-by-step explanation:
Let d = daily fee in dollars
Let +m = milage charge in dollars
In words:
( Cost of rental ) = ( number of days rented )x( daily fee ) + ( miles driven )x( milage fee )
For her first trip:
(1) +240.5+=+4d+%2B+450m+
For her 2nd trip:
(2) +146+=+3d+%2B+200m+
-------------------------
Multiply both sides of (1) by +3+
Multiply both sides of (2) by +4+,
Then subtract (2) from (1)
Answer:
14 miles if that's how far he went up
17miles if you're calculating his distance covered
<span>The sum of the exterior angles of a polygon is always 360 degrees.
You have 6 sides. Each exterior angle must then be 360/60 = 60</span>°
