Answer:
The factors are 3 and -9
Step-by-step explanation:
The given trinomial is 
.
We need to find two factors. We know that,
3(9) = 27
So,
can be written as :
as two factors add up to get -6 and multiply to get -27.
Hence, the factors are 3 and -9.
Answer:
-3/2 (x - 6)
Step-by-step explanation:
Answer:
y = (x - 3)² + 6
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = x² - 6x + 15
add/subtract ( half the coefficient of the x- term )² to x² - 6x
y = x² + 2(- 3)x + 9 - 9 + 15
y = (x - 3)² - 9 + 15
y = (x - 3)² + 6 ← in vertex form
The answer is 2.
You would replace the letters with number which it would be 10/5
Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference between the two given y-coordinates: 4 - (-3) = 7
The change in x is the difference between the two given x-coordinates (note that the order of the difference must be the same as the order of the difference of the y values): 1 - 1 = 0
So, 7/0 is the slope, but you cannot divide by 0, so the slope is undefined.
