For
ax²+bx+c
if a≠1 then use the ac method

1. multiply a and c
2. factor the result such that they add to get b
3. split b up into those 2 factors
4. group and undistribute




so

12x²-1x-6
ac=12*-6=-72
what 2 factors add to -1?
-9 and 8
12x²+8x-9x-6
group
(12x²+8x)+(-9x-6)
undistribute
4x(3x+2)+(-3)(3x+2)
undistribute
(4x-3)(3x+2)

What is the rate of change of the linear relationship modeled in the table (-2,5) (-1,4) (0,3) (1,2)
poizon [28]

The rate of change of the linear relationship is -1.

Explanation:

It is given that there is a linear relationship between all these points, these points lie on a straight line.

The equation to find the slope passing through two points \left(x_{1}, y_{1}\right) and \left(x_{2}, y_{2}\right) is given by

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the points (-2,5) and (-1,4), we get,

\begin{aligned}m &=\frac{4-5}{-1+2} \\&=\frac{-1}{1} \\&=-1\end{aligned}

Thus, the slope is -1.

Thus, the rate of change of the linear relationship is -1.

192 rounded to nearest tenth?
Andrews [41]

There is no TENTH in 192 so 192 rounded to the nearest TENTH is 192.


If you meant TEN then 192 rounded to the nearest TEN is 190.

Good Luck!
