Answer:
W = 12
L = 16
Step-by-step explanation:
Givens
L = L
W = 1/2 L + 4
Perimeter = 56
Formula
2L + 2W = Perimeter
Solution
Sustitute
2L + 2(1/2L + 4) = 56
2L + L + 8 = 56
3L + 8 = 56
3L + 8 - 8 = 56 - 8
3L = 48
3L/3 = 48/3
L = 16
W = 1/2 L + 4
W = 8 + 4
W = 12
Check
2L + 2W = 56
2*16 + 2*12 = 56
32 + 24 = 56
56 = 56 and it checks.
Answer:
The constant speed with Ed is travelling is 60 mile per hour
Step-by-step explanation:
Given as :
The distance cover to travel from Jefferson to Holden is (D1) 250 miles
The distance cover to travel from Holden to Paxton is (D2) 50 miles
Total time taken to complete entire journey = T = 5 hours
Let The constant speed of Ed = S mph
Time = 
Or, Time = 
+ 
Or, 5 hour = 
+ 
Or, 5 × S = 250 + 50
So, 5 × S = 300
∴ S = 
I.e S = 60 mph
Hence , The constant speed with Ed is travelling is 60 mile per hour Answer
Answer:
WHere are the graphs
Step-by-step explanation:
:)
Answer: D
Explanation:
The equation of a line in the point slope form is expressed as
y - y1 = m(x - x1)
where
m represents slope
x1 and y1 represents coordinates of the point that the line passes.
From the information given, the equation of the path of the old route is
y = 2x/5 - 4
Recall, the equation of a line in the slope intercept form is expressed as
y = mx + c
By comparing both equations,
slope, m = 2/5
If two lines are parallel, it means that they have the same slope. Given that the new route is to be parallel to the old route and will go through point (Q, P), then
m = 2/5
x1 = Q
y1 = P
The equation of the new route be
y - P = 2/5(x - Q)
