Answer:
y= -1; x=5
Step-by-step explanation:
Replace the x in the first equation with x=1-4y
2(1-4y)+7y=3
2-8y+7y=3
-y=1
y= -1
x=1-4(-1))
x=5
Hope this helps
A.
For this case, let us set the variables:
s = 0 (final destination on the ground)
t = unknown
vo = 0
so = 8000 ft
Using the equation, we calculate for t:
0 = -16 t^2 + 0t + 8000
t = 22.36 s
B.
For this case:
s = unknown
t = 22.36 s
vo = 600 miles/hr = 880 ft/s
so = 0
Using the equation, we calculate for s:
s = -16*(22.36)^2 + 880*22.36 + 0
s = 11, 677.29 ft = 2.21 miles
Answer:
My answer 2 hour
Step-by-step explanation:
If whats-his-face can do it in 4 and girl can do it in 2 divide 4 and 2 and get 2.
Hope you get it right tell me if this is correct or not.
