Question 160130: i relllyyyyyyyyyyyyyyyyy reallyyyyyyyyyyyyyyyyyyyyyyyyy neeed to get the answers for these problems, if your coulddddddddddddd do it for me i would ask god to blessssssssssssssssss u ....... plz plz plz....
1) subtract this: (4x/x^2+8x+12)-(x+7/x^2+3x-18) = ?
2) divide this: (4x^2-25/4x^2+20x+25)/(6x-15) = ?
3) perform the indicated operations and simplify the result. Leave your answer in factored form : 1-(2/2-5/x)
4) simplify : 27x^5y^-2/3x^-4y^0 = ?
(use positive exponents only)
5) simplify: (27a^2b^3)^2/3 = ? ( write the results using positive exponents.
6) solve for the indicated variable. Tx + Uy=V; f or y (U ≠0)
Y= ? , U ≠ 0
7) solve. (m/5)-2<(7/5)-(m/4) m ? then ? (simplify your answer. Type an integer or a fraction)
8) solve and graph : 5≤4x-3<29 ( solve the inequality… simplify your answer. Type an integer or fraction)
9) A jazz concert bought in $176,500 on the sale of 8500 tickets. If the tickets sold for $15 and $25 each, how many of each type of ticket were sold?
The number of $15 tickets is ?
10) you have $250,000 in an IRA (individual retirement account) at the time you retire. You have the option of investing this money in two funds: Funds A pays 5.3% annually and Fund B pays 7.8% annually. How should you divide your money between fund A and Fund B to produce an annual interest income of $14,750?
You should invest $? In Fund A and $? In Fund B.
11) Write the equations of the vertical and horizontal lines through the point (2,9).
What is the equation of vertical lines?
12) Write the equation of the line through the indicated point with the indicated slope. Write the final answer in the form y=mx+b. m= -7; (5, -4)
Y= ? ( type your answer in slope-intercept form)
okkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk i know its a lo, but please email me if you can i would keep in touch .. thank u soooooooooooooooooo much .. i hope it would work this way

You can put this solution on YOUR website! 1) subtract this: (4x/x^2+8x+12)-(x+7/x^2+3x-18) = ?
4X/(X+6)(X+2)-(X+7)/(X-3)(X+6) COMMON DENOMINATOR=(X+6)(X+2)(X-3)
[4X(X-3)-(X-7)(X+2)]/(X+6)(X+2)(X-3)
[4X^2-12X-X^2-2X+7X+14]/(X+6)(X+2)(X-3)
[3X^2-7X+14]/(X+6)(X+2)(X-3) ANSWER
2) divide this: (4x^2-25/4x^2+20x+25)/(6x-15) =
[(2X+5)(2X-5)/(2X+5)(2X+5)]/3(X-5)
[(2X-5)/2X+5)]*3(X-5)
(2X-5)*3(X-5)/(2X+5)
3(2X^2-15X+25)/(2X+5)
3(2X-5)(X-5)/(2X+5) ANSWER.
3) perform the indicated operations and simplify the result. Leave your answer in factored form : 1-(2/2-5/x)
1-(1-5/X)
1-1+5/X
5/X ANSWER.
4) simplify : 27x^5y^-2/3x^-4y^0 = ?
(use positive exponents only)
27X^5*3X^4/Y^2*1
27X^9/Y^2 ANSWER.
5) simplify: (27a^2b^3)^2/3 = ?
( write the results using positive exponents.
(27A^2/B^3)^2/3
(27A^4/B^6)^1/3
CUBERT(27A^4/B^6)
3A/B^2CUBERT(A) ANSWER.
I'LL LEAVE THE REST FOR YOU TO PRACTICE WITH.
