x - c/2 = -3 c/2
Add c/2 to each side of the equation:
x = -2 c/2
Simplify the fraction on the right side:
<u>x = -c</u>
B. y=n+20; 25,26,27 because if you plug in 1 into the equation it equals
21. 2+20=22, etc. so to find the next three terms of the equation plug
in 5: y=5+20=25; plug in 6: y=6+20=26; and plug in 7: y=7+20=27
Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
Answer: 2.5$
Step-by-step explanation: Since 1 hour is half of 2 hours and the price to park for 2 hours is 5. We can take half of the 2 hour parking price to find the 1 hour price.
5$/2 Hours = 2.5$ per hour
