Answer:
36
Step-by-step explanation:
The number of two of the nine members of ski patrol unit can be chosen is equal to the combinations of 9 taken 2. This can be calculated using the formula:
=
, where
9! =9×8×7×6×5×4×3×2×1 and
7!=7×6×5×4×3×2×1
2!=2×1 then the equation becomes:
=
=36
The slope is 1/3

Answer:
892.85 miles for 22 days
Step-by-step explanation:
This Question is related to Direct Proportionality
Here : The Number of Miles Driven is Directly Proportional to Number of Gallons of Gas
Number of Miles ∝ Gallons of Gas
Given Keith with 16 Gallons of Gas Drove 436 Miles
⇒ Keith with 1 Gallon of Gas would Drive -
Miles
⇒ Keith with 1 Gallon of Gas would Drive : 27.25 Miles
⇒ Keith with 14 Gallons of Gas would Drive : 14 × 27.25 Miles
⇒ Keith with 14 Gallons of Gas would Drive : 381.5 Miles
-x-5
- -5x^2 - 3
or
(-x-5) - (-5x^2 - 3)
First, distribute the -. So then it becomes
-x - 5 + 5x^2 + 3
Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
- x + 5x^2 -2
However, you order in exponents so
5x^2 - x - 2
would be the correct answer.
