-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy
—> -6x2(expo) - 28y2(expo) + 26xy
Check the answer again just to be sure, it’s been a while since I’ve had algebra!
Label the vertical axis to show the frequencies. For each interval, count the number of data values from the stem-and- leaf plot<span>. </span>Draw<span> a bar with a height of the number of data values in that interval. In the </span>stem-and-leaf plot<span> in Example 1, the </span>stems<span>represent the tens place of each data value. is this what you need

Answer:
Could you take a picture of the question ?
Your equation
is in the form
The vertex only relies on "a" and "b" though, so that +9 doesn't really matter in this case. The vertex of a parabola is located where
So your x-coordinate is -1. You need to find f(-1) to find your y-coordinate, and then you list it in the form (-1, y).
