Answer:

f(x)=(x+3)^{2}-20

Step-by-step explanation:

we have

f(x)=x^{2}+6x-11

To convert to vertex form complete the square

f(x)=(x^{2}+6x+3^2)-11-3^2

f(x)=(x^{2}+6x+9)-20

Rewrite as perfect squares

f(x)=(x+3)^{2}-20 ----> equation in vertex form

The vertex is the point (-3,-20) (is a minimum)

A room can be cleaned in 2 hours if rob and Harry work together. Ron could clean it in 3 hours. How long can harry clean it?
tresset_1 [31]

Answer:

6 hours

Step-by-step explanation:

Let the total work be X

Combined speed: X/2

Ron's speed: X/3

Harry's speed: S

X/2 = X/3 + S

S = X/2 - X/3 = (3X - 2X)/6 = X/6

Harry's speed is X/6, so he'll take 6 hours

Line p passes through A(-2, -4) and has a slope of 1/2 What is the standard form of the equation for line p?
yarga [219]
Point slope form is y-(-4) = 1/2(x-(-2)

y+4 =1/2 (x+2)

now the standard form 2y+8=x+2
so -x+2y=-6 is the equation for line p in standard form
