Answer:
4x^2-25x-19
Step-by-step explanation:
First off you got to distribute all the negative signs that were given. After distributing you gotta do it again to the remaining then after that, you must combine all like terms and get rid of them.
What we are going to do in this case is to simplify the expression step by step.
We have then:
SqrR (3x ^ 12 * y ^ 10) / SqrR (5x ^ 6 * y ^ 3)
SqrR (3x ^ 12 * y ^ 10 * y) / SqrR (5x ^ 6 * y ^ 3 * y)
We use square root properties:
((x ^ 6 * y ^ 5) * SqrR (3y)) / ((x ^ 3 * y ^ 2) * SqrR (5))
We use power properties:
((x ^ (6-3) * y ^ (5-2)) * SqrR (3y)) / (SqrR (5))
((x ^ 3 * y ^ 3) * SqrR (3y)) / (SqrR (5))
((x ^ 3 * y ^ 3) * SqrR (15y)) / (SqrR (25))
1/5 * ((x ^ 3 * y ^ 3) * SqrR (15y))
Answer:
D. none of these
You must drive more than 40 miles to make option A the cheaper plan
<em><u>Solution:</u></em>
Two payment options to rent a car
Let "x" be the number of miles driven in one day
<em><u>You can pay $20 a day plus 25¢ a mile (Option A)</u></em>
25 cents is equal to 0.25 dollars
OPTION A : 20 + 0.25x
<em><u>You pay $10 a day plus 50¢ a mile (Option B)</u></em>
50 cents equal to 0.50 dollars
Option B: 10 + 0.50x
<em><u>For what amount of daily miles will option A be the cheaper plan ?</u></em>
For option A to be cheaper, Option A must be less than option B
Option A < Option B
Solve the inequality
Add -0.50x on both sides
Add - 20 on both sides,
Divide both sides by 0.25
Thus you must drive more than 40 miles to make option A the cheaper plan
Answer:
the issue will be for 4/5
A- $2,250
This is because you do 5000 × 0.045 × 10
