# How do you solve (y^2-4)/(y+3) = 2- (y-2)/(y+3)?
May 26, 2015
First multiply all the terms by $\left(y + 3\right)$ to get:
${y}^{2} - 4 = 2 \left(y + 3\right) - \left(y - 2\right)$
$= 2 y + 6 - y + 2$
$= y + 8$
Subtract $\left(y + 8\right)$ from both sides to get:
${y}^{2} - y - 12 = 0$
This factors as $\left... | HuggingFaceTB/finemath | |
## The Gamma Family¶
You have seen in exercises that a non-negative random variable $X$ has the gamma $(r, \lambda)$ distribution for two positive parameters $r$ and $\lambda$ if the density of $X$ is given by
$$f_X(x) ~ = ~ \frac{\lambda^r}{\Gamma(r)} x^{r-1}e^{-\lambda x}, ~~~~~ x \ge 0$$
Here $$\Gamma(r) ~ = ~ \i... | HuggingFaceTB/finemath | |

# college alg
posted by on .
find the equation of a line that is perpendicular to line y=1/6x+6 and contains point (-7,0)
y=?
please show work so i can see how its done
• college alg - ,
slope of y = (1/6)x + 6 is 1/6
so slope of perpendicular is -6
equation is y = -6x + b
but (-7,0) lies on it
0 = -6(-7) + b

# Vector norms are only on column vectors? How about row vectors?
When I studied on norms: vectors are defined by : $$x\in R^n$$.
Many books said $$x$$ is a column vector. (Also, define inner product $$x^tx$$.)
What I am curious about is : $$||x|| =||x^t||$$? (any) norms of vector and its transpose are the same.
