Answer: The range is  \{y \in \mathbb{R}\ | \ y \le -6\}

Explanation:

The parabola opens down, forming a "frowny face" in a way (just without the eyes). Or you can think of it as a hill or mountain. This means that the vertex (-3,-6) is at the top of that mountain. It's the highest point of that parabola.

The range is the set of all possible y values. We see that y = -6 is the largest it can get. So y = -6 or y is smaller than this. We would then write y \le -6 to describe all the possible y values.

Therefore, the range is \{y \in \mathbb{R}\ | \ y \le -6\}

This translates to "y is a real number such that y is -6 or smaller".

So the second answer you wrote is close, but you forgot the "or equal to" portion of the inequality sign.

See below for a visual example of what's going on.

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr
soldier1979 [14.2K]
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170

And that is the answer.

PLEASE PLEASE PLEASE HELP ME WITH THIS MATH
Rasek [7]
(x,y)=(x1+k(x2-x1),y1+k(y2-y1))
 k is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio.
 k=3/(3+7)=3/10.
 Point A is located at (5, 10) and point B is located at (20, 25).
 (x,y)=(5+(3/10)*(20-5),10+(3/10)*(25-10))
 (x,y)= (9.5,14.5)
 The answer would be 
 (9 1/2, 14 1/2)
