Answer:

y = - $\frac{1}{6}$ x - $\frac{8}{9}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x + 18y = - 16 into this form

Subtract 3x from both sides

18y = - 3x - 16 ( divide all terms by 18 )

y = - $\frac{3}{18}$ x - $\frac{16}{18}$ , that is

y = - $\frac{1}{6}$ x - $\frac{8}{9}$ ← in slope- intercept form

Suppose f(x, y) is a differentiable function of x and y and let g(r, s) = f (2rs, 8s − 2r). Use

worty [1.4K]

By the chain rule,

$\dfrac{\partial g}{\partial r} = \dfrac{\partial f}{\partial r} \\\\ ~~~~~ = \dfrac{\partial f}{\partial x} \dfrac{\partial x}{\partial r} + \dfrac{\partial f}{\partial y} \dfrac{\partial y}{\partial r} \\\\ ~~~~~ = 2 s \dfrac{\partial f}{\partial x} - 2 \dfrac{\partial f}{\partial y}$

where $x(r,s)=2rs$ and $y(r,s)=8s-2r$ .

If $r=2$ and $s=1$ , then

$x = 2\cdot2\cdot1 = 4$

$y=8\cdot1-2\cdot2 = 4$

so that

$g_r(2,1) = 2\cdot1 f_x(4,4) - 2 f_y(4,4) = 2\cdot2-2\cdot3 = \boxed{-2}$

(y-3)(y+10) find the product please

allochka39001 [22]

Answer:

y^2 +7y-30

Step-by-step explanation:

Step 1: Use FOIL

y·y = y^2

y· 10= 10y

-3·y= -3y

-3·10= -30

Step 2: <em>combine like terms</em>

y^2+ 10y-3y-30

7^2+ 7y-30

and thats all :)

hope this helped

The midpoint of \overline{\text{AB}} AB is M(0, -3)M(0,−3). If the coordinates of AA are (2, -5)(2,−5), what are the coordinates

ICE Princess25 [194]

Using the mid-point concept, it is found that the coordinates of B are (-2, -1).

The mid-point of two points is the <u>mean of the coordinates of each point</u>.

In this problem:

The points are: A(2, -5) and B(x,y).

The mid-point is (0, -3).

Applying the concept for both the x and y-coordinates, we have that:

$\frac{x + 2}{2} = 0$

$x + 2 = 0$

$x = -2$

$\frac{-5 + y}{2} = -3$

$-5 + y = -6$

$y = -1$

The coordinates of B are (-2, -1).
