Answer:

x=-19

Step-by-step explanation:

Distribute

−4(x+1)−3=−3(x−4)

−4−4−3=−3(−4)

Subtract the numbers

-4x-4-3(x-4)

−4x−4−3=−3(x−4)−4−7=−3(−4)

Distribute again..

−4x−7=−3(x−4)

−4-7=−3+12

Add 7 to both sides and then Simplify!

Please help! what is the polar equation r = -5 theta in parametric form? thank you!

Rudiy27

Use these equations when converting polar equations to parametric equations:

$x=r\cos\theta$

$y=r\sin\theta$

We know that $r=5\theta$ , so substitute that into both equations for x and y.

$x=5\theta\cos\theta$

$y=5\theta\sin\theta$

Now, replace $\theta$ with any variable that you want to represent the parametric equations in. I'll use the standard variable, $t$

$x=5t\cos t$

$y=5t\sin t$

Thus, $r=5\theta$ represented in parametric form is:

$(x,y)=(5t\cos t, 5t \sin t)$

Let me know if you need any clarifications, thanks!

If one inch = 2.54 centimeters, then 45 centimeters divided by 2.54 centimeters will give you the amount of inches the piece of wood needs to be.

45/2.54 = 17.72 ---- Rounded to the nearest quarter, would be 17.75 inches.
