Answer:

<h3>0 and undefined. </h3>

Step-by-step explanation:

<h3><u>SLOPE FORMULA:</u></h3>

y₂-y₁/x₂-x₁=rise/run

<h3><u>SOLUTIONS:</u></h3>

y₂=(-7)

y₁=(-7)

x₂=2

x₁=(-6)

Solve.

$\displaystyle \mathsf{\frac{(-7)-(-7)}{2-(-6)}=\frac{0}{8}=\boxed{\mathsf{0}} }}$

The slope is 0 and undefined, which is our answer.

15+6=33m-21-27m<br><br> combining like terms (show work)

marin [14]

Answer:

$m = \boxed 7$

Combine like terms

$21=33\cdot \mathrm{m}-21-27\cdot \mathrm{m}$

Group like terms

$21=\left(33\cdot \mathrm{m}-27\cdot \mathrm{m}\right)-21$

Simplify the arithmetic

$21=6\cdot \mathrm{m}-21$

Swap sides

$6\mathrm{m}-21=21$

Eliminate the parameter,t, in the parametric equation, x=6cos t, and y =3 sin t

german

X = 6 cos(t)
y = 3 sin(t)

we can rewrite these equations as:

$\frac{x}{6}=cost(t) \\ \\ \frac{y}{3} =sin(t)$

Taking squares of both equations we get:

$( \frac{x}{6})^{2}=sin^{2} (t) \\ \\ 
( \frac{y}{3})^{2}=cos^{2}(t)$

Adding both the equations, we get:

$\frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=sin^{2}(t)+cos^{2}(t) \\ \\ 
 \frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=1$
