Ok

fisrt we determine sign
negative divided by positive=negative
answer is negative
disregard any signs for now
first convert to from mixed to improper
3 and 1/5=3+1/5=15/5+1/5=16/5

(16/5)/(2/15)
remember the fancy 'invert and multiply'
I won't tell you why because it would take too long, but if you want to know why we invert and multiply, just ask in comments

so, invert an multilply
(a/b)/(c/d)=(ad)/(bc)
(16/5)/(2/15)=(16*15)/(5*2)=(240)/(10)=24

the answer is negative so

-24 is answer

What is the vertex of y = x2 + 2x +2<br> O (1,-1)<br> O (2,-2)<br> O (1, 2)<br> 0 (-1, 1)
fredd [130]

Answer:

vertex = (- 1, 1 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

y = x² + 2x + 2 ← is in standard form

with a = 1 and b = 2 , then

x = - \frac{2}{2} = - 1

substitute x = - 1 into the equation for y- coordinate of vertex

y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1

vertex = (- 1, 1 )
