$\bf P(\stackrel{x_1}{-2}~,~\stackrel{y_1}{4})~\hspace{10em}
slope = m\implies 3
\\\\\\
\begin{array}{|c|ll}
\cline{1-1}
\textit{point-slope form}\\
\cline{1-1}
\\
y-y_1=m(x-x_1)
\\\\
\cline{1-1}
\end{array}\implies y-4=3[x-(-2)]\implies y-4=3(x+2)
\\\\\\
y-4=3x+6\implies y=3x+10$

Which of the following describes the graph of y = x² - 225?

lara [203]

Answer:

option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.

Step-by-step explanation:

we have

$y=x^{2} -225$

This is the equation of a vertical parabola open upward (the leading coefficient is positive)

The vertex represent a minimum

The vertex is the point (0,-225)

The axis of symmetry is x=0 (y-axis)

Find the x-intercepts (values of x when the value of y is equal to zero)

For y=0

$0=x^{2} -225\\x^2=225$

square root both sides

$x=\pm15$

therefore

The graph has zeroes at x = 15 an x = -15 and it opens upward.

Two angles are vertical angles. One is labeled 2x. The other angle is labeled (x+30). Find the value of x.

NeX [460]

2x=x+30

-x -x

x=30

The value of x is 30
