AC is in the range (2x - 10, 14x + 4)

yes because ab plus bc is ac

the midpoint of AB.

associative? single replacement

If: y = x^2 -4x +8 and y = 8x -x^2 -14 Then: x^2 -4x+8 = 8x -x^2 -14 Transposing terms: 2x^2 -12x+22 = 0 Divide all terms by 2: x^2 -6x +11 = 0 Using the discriminant b^2 -4(ac): 36 -4(1*11) = -8 Therefore it follows that there are no points of intersection because the discriminant is less than zero.

Are you sure that the given expressions are right? Because we are dealing with complex numbers (a little bit work for this kind of exercise).ab = 4x + 8bc = 8x + 4ac = 18x - 11b = a/(4x + 8)c = b/(8x + 4) = [a/(4x + 8)[/(8x + 4) = a/[(4x + 8)(8x + 4)]c = a/(18x - 11)a/[(4x + 8)(8x + 4)] = a/(18x - 11) this happens only when:(4x + 8)(8x + 4) = (18x - 11)32x^2 + 16x + 64x + 32 = 18x - 1132x^2 + 62x + 43 = 0x = [-62 ± √(62^2 - (4)(32)(43)]/[(2)(32)]x = [-62 ± √(-1660)]/64x = [-62 ± i√(1660)]/64x = -62/64 ± i√(1660/4096) (64^2 = 4096)x = -31/32 ± i√[415/1024]Substitute -31/32 ± i√[415/1024] for x, and find the value of ab, bc, and ac.ab = 4x + 8bc = 8x + 4ac = 18x - 11

No, It is is a double replacement. AB +CD = AC + BD

This is a 'Sngle Displacement' reaction ( A + BC --> AC + B

This kind of chemical reaction is usually called "displacement" and sometimes "substitution".

Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.

If AC equals 6 and BD equals 4, then AB equals 5.

It would be a straight line of length bc

You could conclude that B lies between A and C.

ac is 7 if b is 3 and a is 2 a nd c is 5

Single displacement reactions follow the form A + BC equals AC + B. Because the sodium and the hydrogen switch places, this reaction is considered single displacement.

If point b is in between points a and c, then ab +bc= ac by the segment addition postulate...dont know if that was what you were looking for... but that is how i percieved that qustion.
