Answer:

n = 3

Step-by-step explanation:

Hello!

p = 2n - 3

the question asks for when p is equal to 3 so we put 3 in for p

3 = 2n - 3

Now we can solve this

3 = 2n - 3

Add 3 to both sides

6 = 2n

Divide both sides by 2

3 = n

The answer is n = 3

Hope this Helps!

You can reword the two equations as:

-5x-y=15 (Divide original value by 3)
-2x+6y=6

Then use elimination to find x:

-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6

You're left with:

-32x=96. Which can then be solved to find x which is -3.

Then plug back in 

-2x+6y=6

Now to: -2(-3)+6y=6.

Which reduces to 6+6y=6. So y=0.



To graph them, just reword the equations (yes once again) so that y is in front.

y=-5x-15 and y=(1/3)x+1

Centripetal acceleration is given by:
g=v^2/r
where:
v=velocity
r=rate
But
V=200 m/s, g=9.8 m/s^2
plugging the values in the formula we obtain:
9.8=200^2/r
r=200^2/9.8
r=4081.63 m

Formula for finding area of a trapezoid :

<u>A = 1/2 x (a + b) x h</u>

  1. a and b = parallel sides of the trapezoid
  2. h = height of the trapezoid

Solving :

  • A = 1/2 x (38 + 14) x 16
  • A = 8 x 52
  • A = <u>416 square centimeters</u>

How do you solve x^2+11x+18=0 with either quadratic formula. factoring. or squarerooting
Lostsunrise [7]
I always prefer factoring, if there are simple factors.
There are simple factors here.

x² + 11x + 18 = 0

(x + 2) (x + 9) = 0

The left side is zero if either factor is zero.

First factor:
x + 2 = 0
<u>x = -2</u>

Second factor:
x + 9 = 0
<u>x = -9 </u>
