$\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ f(x)=\stackrel{\stackrel{a}{\downarrow }}{3}x^2\stackrel{\stackrel{b}{\downarrow }}{-24}x\stackrel{\stackrel{c}{\downarrow }}{+8} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left(-\cfrac{-24}{2(3)}~~,~~8-\cfrac{(-24)^2}{4(3)} \right)\implies (4~~,~~8-48)\implies (4~~,~-40)$

What can you say about the unknowns in the equation x+22=y+32

Llana [10]

Answer:

x = y + 10

y = x -10

Step-by-step explanation:

For x:

Given: x + 22 = y + 32

Subtract 22 from both sides: x = y + 32 - 22

Answer: x = y + 10

For y:

Given: x + 22 = y + 32

Subtract 32 from both sides: x + 22 - 32 = y

Answer: y = x -10

I think this is what you are asking for? If not lemme know, have a nice day! :D

(also, this is my 300th answer hehehehe)

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{3}}}\implies \cfrac{-3}{-1}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{3}(x-\stackrel{x_1}{3}) \\\\\\ y-4=3x-9\implies y=3x-5$
