Answer:
u=−x2−x+1
Step-by-step explanation:
Let's solve for u.
2x−u−1x^2−3x+3=2
Step 1: Add x^2 to both sides.
−x2−u−x+3+x2=2+x2
−u−x+3=x2+2
Step 2: Add x to both sides.
−u−x+3+x=x2+2+x
−u+3=x2+x+2
Step 3: Add -3 to both sides.
−u+3+−3=x2+x+2+−3
−u=x2+x−1
Step 4: Divide both sides by -1.
−u/−1=x2+x−1
−1/u=−x2−x+1
Answer:
u=−x2−x+1
Since there are 60 seconds in a minute multiply 8 by 60
The rate is 480 feet per minute.
Answer:
6days
total cost-$66
additional days-5
Step-by-step explanation:
41+5(x-1)=31+7(x-1)
41+5x-5=31+7x-7
36+5x=24+7x
12=2x
x=6
36+30=66
