The answer is :
25 × 10^-3 = 0.025
The derivate is. f'(x)=2x+1 .then f'(-1)=-2+1=-1
120/2 = x/5....120 miles to 2 hrs = x miles to 5 hrs
cross multiply
(2)(x) = (120)(5)
2x = 600
x = 600/2
x = 300....the motorcyclist would travel 300 miles in 5 hrs
or u could do it this way..
120/2 = 60 miles per hr
60 * 5 = 300 miles
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
8y-3=6y+17 first subtract 6y from both sides to make it
2y-3=17 then add 3 to both sides to get 2y=20 then you will divide each side by 2 and you get y=10
