50 miles = 1 hour
10 miles = 1/50 x 10
= 1/5 hours
= 12 minutes
It will take him 12 minutes to drive 10 miles.
3.2 x 108 The 8 is suppose to be an exponent of 10
Q: "Simplify the following expression (2x+y-z)^2-(2x+y+z)^2"
As a simplified expression is
A: -8xz - 4yz
Hopefully this helps you ^0^
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
<u>y = ± sqrt( -x/6 -12.666) + 2 </u>
Answer:
Forgot to turn the 7% into a 0.7... if you dont do that, then it will come out larger then it was supposed to be :)
