$R(r_1+r_2)=r_1r_2\\
Rr_1+Rr_2=r_1r_2\\
Rr_2-r_1r_2=-Rr_1\\
r_2(R-r_1)=-Rr_1\\
r_2=-\dfrac{Rr_1}{R-r_1}
$

How do you find the vertex and axis of symmetry for this function, <br><br> F(x)=3(x+1)^2

Andrews [41]

Answers:
Vertex is (-1,0)
Axis of symmetry is x = -1

============================================

Explanation:

F(x) = 3(x+1)^2
is the same as
y = 3(x-(-1))^2 + 0
which is in the form
y = a(x-h)^2 + k

We can see that
a = 3
h = -1
k = 0

Therefore the vertex is (h,k) = (-1,0)
The axis of symmetry is x = h = -1 which is the equation x = -1

The axis of symmetry in this case is a vertical line through the vertex.

If that's Khan Academy, one thing you can do is turn off your wifi, answer, then turn it on again. If you look closely the bottom right will show if ur answer was correct or not correct. Then you get a second chance to answer without getting it wrong!

I think it's

Greatest = x+y

Least = -x

Closest = x-y

(Tough day dividing polynomials and I'm still lost!) Please help me my hands are legit numb:)

Answer:

Option D. 9

Step-by-step explanation:

There are two ways to obtain the answer to the question.

Method 1:

Let 2x + 1 = 0

Making x the subject, we have

2x + 1 = 0

Collect like terms

2x = –1

Divide both side by 2

x = –1/2

Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:

4x³ – 6x² – 8x + 7

x = –1/2

4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7

4(–1/8) – 6(1/4) – 8(–1/2) + 7

–1/2 – 3/2 + 4 +7

– 4/2 + 4 + 7

– 2 + 4 + 7

= 9

Method 2:

Divide 4x³ – 6x² – 8x + 7 by 2x + 1
