Answer:

12n-72

Step-by-step explanation:

You would say 12(n-6) because the difference of a number would be n and the difference is 6. When it says 12 times, then you will multiply it by the numbers in the parentheses.

Vertex is at $\left(-3,-6\right)$

y-intercept is 3.

The parabola opens up.

Step-by-step explanation:

The graph of the equation is hereby attached in the answer area.

Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here( $x =-3$ ), is shown with the dotted line in the graph attached.

y-intercept is defined as the value of y where the graph crosses the y-axis. In other words, when $x=0$ . Putting

And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of $x$ in the given equation $y =x^{2} + 6x + 3$ . Here, co-efficient of

So, vertex is at $\left(-3,-6\right)$

y-intercept is 3.

The parabola opens up.

What is the distance between the points (21,-30) and (3,8)

Scilla [17]

Answer:

approximately 42.05

Step-by-step explanation:

We know that the distance formula is $\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }$ , so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
