Point slope eqaution is
y-y1=m(x-x1)---------equation1

find m slope=y2-y1/x2-x1
m=-3+1/3+4=-2/7

so put those all values in eqaution 1
<span>(x1, y1) as (-4, -1).</span>
y+1= - 2/7(x+4)

How are ROC (rate of change) and slope related AND different

Mrrafil [7]

Answer:

Rate of change and slope is the same since they are both terms of every rate, but rate of change can be said in any terms as in exponential and linear, etc. While slopes are only for linear equations.

The number of cubic feet of water in a curved container can be approximated by v = 0.95h2.9. use a calculator to find the amount

Black_prince [1.1K]

V=0.95h^2.9
h=7.5 feet→V=0.95(7.5)^2.9
V=0.95(344.8876664)
V=327.6432830
Rounded to the nearest tenth:
V=327.6 cubic feet

Match the products of rational expressions with their simplest forms.

Alborosie

Lets simplify each one of the rational expressions using the product rule of exponents: $a^n*a^m=a^{n+m}$ and the quotient rule of exponents: $\frac{a^n}{a^m} =a^{n-m}$ .

1. $\frac{-3x^2}{2y^2} * \frac{y^2}{9x} =- \frac{x}{6} = \frac{-1}{6} x$

2. $\frac{5y^2}{10x^2} * \frac{4x^2}{y} =2y$

3. $\frac{-9y^2}{5x} * \frac{-10x^2}{3y} =6xy$

4. $\frac{14x^2}{5y} * \frac{-10y}{7x} =-4x$

We can conclude that you should pair the rational expressions with their simplest form as follows:
$6xy-----\ \textgreater \ \frac{-9y^2}{5x} * \frac{-10x^2}{3y}$
$\frac{-1}{6} x-----\ \textgreater \ \frac{-3x^2}{2y^2} * \frac{y^2}{9x}$
$-4x-----\ \textgreater \ \frac{14x^2}{5y} * \frac{-10y}{7x}$
$2y-----\ \textgreater \ \frac{5y^2}{10x^2} * \frac{4x^2}{y}$
