Answer:

x =7

Step-by-step explanation:

3x - 9 + 12 - 6x = -18

Combine like terms

-3x +3 = -18

Subtract 3 from each side

-3x +3 -3 = -18 -3

-3x = -21

Divide each side by-3

-3x /-3 = -21 /-3

x =7

Answer:

$x=7$

Step-by-step explanation:

$3x - 9 + 12 - 6x = -18$

$3x+ - 9 + 12+ - 6x = -18$

$3x+- 6x + - 9 + 12+ = -18$

$-3x+ 3= -18$

$-3x= -18-3$

$-3x= -21$

$3x=21$

$x=21/3$

$x=7$

What is the magnitude of the vector?

viktelen [127]

Answer:

$\boxed{\sqrt{65}}$

Step-by-step explanation:

Magnitude is solved with the following equation: $\sqrt{x^{2}+y^{2}}$

Therefore, just plug in your x and y-values and solve.

$\sqrt{4^{2}+7{^{2}}$

$\sqrt{16 + 49}$

$\sqrt{65}$

Because $\bold{\sqrt{65}}$ cannot be simplified further, this is the magnitude of the vector.

Can i pls get some help here with how to even solve it using clear steps?

kirill [66]

first off, let's split the triplet into two equations, then from there on we'll do substitution.

$\cfrac{y}{x-z}=\cfrac{x}{y}=\cfrac{x+y}{z}\implies \begin{cases} \cfrac{y}{x-z}=\cfrac{x}{y}\\[2em] \cfrac{x}{y}=\cfrac{x+y}{z} \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{using the 1st equation}}{\cfrac{y}{x-z}=\cfrac{x}{y}\implies }y^2=\underline{x^2-xz} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{using the 2nd equation}}{\cfrac{x}{y}=\cfrac{x+y}{z}\implies }xz=xy+y^2\implies \stackrel{\textit{substituting for }y^2}{xz=xy+(\underline{x^2-xz})}$

$2xz=xy+x^2\implies 2xz=x(y+x)\implies \cfrac{2xz}{x}=y+x \\\\\\ 2z=y+x\implies 2=\cfrac{y+x}{z}\implies 2=\cfrac{x+y}{z} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{}{ \begin{cases} \cfrac{y}{x-z}=\cfrac{x}{y}\\[2em] \cfrac{x}{y}=\cfrac{x+y}{z} \end{cases}}\implies \begin{cases} \cfrac{y}{x-z}=\cfrac{x}{y}\\[2em] \cfrac{x}{y}=2 \end{cases}\implies \begin{cases} \cfrac{y}{x-z}=2\\[2em] \cfrac{x}{y}=2 \end{cases}$

that of course, is only true if x + y, or our numerator doesn't turn into 0, if it does then our fraction becomes 0 and our equation goes south. Keeping in mind that x,y and z are numeric values that correlate like so.
