Hey!
Hope this helps...

So to solve this, we want to know how many miles can we do in every 1 gallon of gas.
To solve this, we do: 380 / 14 = 27.14 miles for every 1 gallon
Okay, so if we have 1/2 a gallon stashed away, how far can we get on every 1/2 gallon...
To solve this, we do: 27.14 / 2 = 13.57 miles for every 1/2 gallon
So...
The answer is: We will NOT be able to get to the Gas Station that is 15miles away, because we can only go about 13.5 miles with every 1/2 gallon.
0.5 => 5/10 => 1/2
12.3 => 123/10
0.07 => 7/100
0.625 => 625/1000 => 25/40 => 5/8
Answer:
(x-8)(x-2)
Step-by-step explanation:
factors of 16:
1 x 16
2 x 8
4 x 4
i'll select 2 and 8 as values because they can add up to 10
(x-8)(x-2)
i made them both negative so the middle term would be -10 but, when multiplied, would equal positive 16
Easy
remember
x^-m=1/(x^m)
so
f(-1)=4*7^-1=4*(1/(7^1))=4*(1/7)=4/7
f(2)=4*7^2=4*49=196
