Can someone please check my work for me. Q: Plot the graph of the equations 2x - 3y = 5 and 4x - 6y = 21 and interpret the result. A: 6(2x ¨C 3y = 5) = 12x ¨C 18y = 30 3(4x - 6y = 21) = 12x - 18y = 63 12x ¨C 18y = 30 + 12x - 18y = 63 0 ¡Ù 93

so can you tell me if this is correct.... 4x 5y = 14 -12x + 15y = -42 15(4x 5y = 14) = 60x 75y = 210 5(-12x +15y = -42) = -60x + 75y = -210 60x 75y = 210 + -60x + 75y = -210 = 0 The equations are not independent therefore they have an infinite ...

how would you create an equation for sec(2x) using both sec(x) and csc(x)? the steps i have so far are 1/(cos^2(x)-sin^2(x)) = 1/(1-1)/(sec^2(x)-csc^2(x)) but then i do not know what to do after this.

Is it the same thing? I don't know, but my first choice was A. I still do not understand how (p-4+m p2m)-4 / (p-4)-m = (p-4+3m)-4 / p4m = p^16-12m / p^4m where does the 12 fit in? and how does the answer end up as A? = p16-16m

Where did you get 3m from? The problem reads Simplify (p^-4+m p^2m)^-4 ---------------- (p^-4)^-m Theses are the choices A) p-16m + 16 B) p-8m 4 C) p-11m 4 D) p-3m + 16 I say its A or B

What about breaking the fractions a part like this? 5x -2 - 3y -1 = 5 - 3 ----------------- x -1 + y -1 ------- x^2 y --------------------- 1 + 1 ------------ x y = 5y+3x^2 * x^2 y -------- x+y x^2 y(5y+3x) = 5xy^2 + 3x^2 y
