Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
Well, If she takes 15 minutes to pick 135 berries, 30 minutes total would be 270 berries, so if you take another 15 minutes picking berries it would be a total of 405 berries but you still need 81 more. so if she can pick 405 in 45 minutes, it would be around a hour and something.
Hope I helped or at least made you think about it
Slope intercept form
y = mx + b
change it to standard form
ax +by = c
y = -1.7x + 8.5
1.7x + y = 8.5
multiply 10 on both side
17x + 10y = 85
hope this help
Subst. 1/4 for x in f(x) = x^2 + 2: f(1/4) = (1/4)^2 + 2 = 1/16 + 2 = 2 1/16
This is the range when the domain is 1/4. Usually a domain contains more than one number.
