Solve for k, m = 3kx/7 - 9

kap26 [50]

Answer:

(7m + 63)/3x = k

Step-by-step explanation:

m=3kx/7 - 9

add 9 to both sides:

m+ 9 = 3kx/7

multiply both sides by 7:

7(m+9) = 3kx

distribute the 7:

7m+63 = 3kx

divide both sides by 3x:

(7m + 63)/3x = k

Complete the square to the problem X^2+6x-16=0

marishachu [46]

Answer:

Step-by-step explanation:

$(a+b)^2=a^2+2ab+b^2\qquad(*)\\\\-------------------------------\\\\x^2+6x-16=0\qquad\text{add 16 to both sides}\\\\x^2+6x=16\\\\x^2+2(x)(3)=16\qquad\text{add}\ 3^2\ \text{to both sides}\\\\\underbrace{x^2+2(x)(3)+3^2}_{(*)}=16+3^2\\\\(x+3)^2=16+9\\\\(x+3)^2=25\Rightarrow x+3=\pm\sqrt{25}\\\\x+3=-5\ \vee\ x+3=5\qquad\text{subtract 3 from both sides}\\\\\boxed{x=-8\ \vee\ x=2}$
