Thank you!!! 1.) if 8x + 6=6m, what is the value of 4x + 3 in terms of m? answer: 3m 2.)3x +4y=18 y= 3/2x which of the following ordered pairs (x,y) is a solution of the system of equations above? answer: (2,3) 3.) which of the following is equivalent to 3x +4/12? answer: x/4 + 1/3 4.) if x-3 is a factor of the expression x^2 +kx + 12, what is the value of k? answer: -7 5.) if 5/m is less then or equal to 2/3, where m > 0, what is the least possible value of m? answer: 7.5 6.) if f(x) = 3x + n, where n is a constant, and f(2) = 0 then f(n) = ? answer:-24 7.) x - 3 = -2 y=5/x the values of x that satisfy the system of equations above also satisfy which of the following equations? answer: (x-3)(x+5)=0 8.) if 2/3a + 1/2b = 5, and b=4, what is the value of a? answer: it could be both 4.5 or 9/2 9.) what is the smallest integer value of x such that 6/x + 1/2x is less than 1? answer: 7 10.) what is one possible solution to the equation 6/x+1 - 3/x-1 = 1/4? answer: the answer could be both 5 or 7 I REALLY NEED THIS**********

Ans1) 8x+6=6m then u will take the common factor of 8x+6 which is 2(4x+3) so it will be 2(4x+3)=6m then u should find 4x+3 so u will divide both by 2 and it will be 4x+3=3m  so the answer is 3m

Answer:

1) 8x+6=6m then u will take the basic factor of 8x+6 which is 2(4x+3) so it will be 2(4x+3)=6m then u should discover 4x+3 so u will separate both by 2 and it will be 4x+3=3m so the appropriate response is 3m

2) supplant y in the condition by 3/2x so its 3x+4(3/2x)=18 so it will be 3x+4x=18 and after that when u gap to discover x the answee is 2 then u supplant x by 2 in the condition 3(2)+4y=18 then u less 18-6=12 at that point isolate 4 from both side lastly the appropriate response will be 3 so (x,y) is (2,3)
