11-8n=1-3n whats answer

musickatia [10]

Answer:

n=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

11−8n=1−3n

11+−8n=1+−3n

−8n+11=−3n+1

Step 2: Add 3n to both sides.

−8n+11+3n=−3n+1+3n

−5n+11=1

Step 3: Subtract 11 from both sides.

−5n+11−11=1−11

−5n=−10

Step 4: Divide both sides by -5.

−5n

−5

−10

An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p

Nadya [2.5K]

Answer:

$a=-\dfrac{3+9\sqrt{3}}{52}\approx −0.357470332079$

Step-by-step explanation:

Here, we assume that point A is (-1, 0) and point B is (z, 2). Since angle BAD is 60°, we have ...

2/(z+1) = tan(60°) = √3

z = (2/√3) -1

Putting the value of z into the equation for the parabola lets us find "a".

2 = a(z +1)(z -5) = a(2/√3)(2/√3 -6)

Then ...

a = 2/(4/3 -12/√3) = (6√3)/(4√3 -36)

a = -(3+9√3)/52 ≈ −0.357470332079
