I'm confused... what does Z equal? (sorry if this is too many questions...)

r and s are both the roots of the polynomial $ax^2+bx+c$, so r+s is just the sum of the 2 roots. According to Vieta's formulas, that is equal to $\boxed{\frac{-b}{a}}$

 I think its 40 I dunno

Use pythag. 5²-3² = height²  <=>  4 = height

so the are is (4(3+6))/2 = 18

Area = 18

The line of symmetry is x = 4.

30  (Remainder: 5)

I mean with remander like the answer that I fourth grader whould put not with like a period you just put a R

What is 185 divided by 6 with a remander

Here is a quick sketch of  Venn diagram if there were 100 %  students:

   if 10 reprsents 20 %        then there were 50 students in the poll

     25 choose only Blue      15 only red      10   both

For what?

slope = (4+1)/(4-5) = -5

so Point Slope form <=> y+1 = -5(x+4)

so slope intercept <=> y = -5x -21

its 101

I think you can't...

b/a = 1/2

c/b = 3/4         b/a  *  c/b =  c/a  =   1/2 * 3/4 =   3/8

a/b = 2, b/c = 4/3

a/b * b/c = 8/3

a/c = 8/3

=> c/a = 3/8

-7(1+5m)-29<300+7m     expand Left side

-7 - 35m - 29   <  300 + 7m    simplify by gathering 'like' terms

   -42m  < 336    divide by - 42   ( this reverses the <    to > )

      m  > 336/(-42)

       m > -8

x cannot = 2   ( from the denominator)

NUMERATOR   factors to   x ( x+2)(x-4)       the (x+2) in the numerator and denominator cancel and you are left with:

x^2 - 4x = 5

x^2 - 4x - 5 = 0

(x-5)(x+1) = 0       so x = 5 or -1          sum = 4

Here is POINT - slope form

y - -1   = -5/4 ( x - - 4)    re-arrange to slope intercept form

y +1 = - 5/4x  - 5

y = - 5/4 x -6

  I do not know...I just uploaded this one.....   Is the file on your computer?    When you 'browse' for it does it show up in the list in the folder where it is stored ? .....is it in the proper format (like  .jpg ) ?

p1 = p2 -3

p2

p3 = p2 -2

p4 = p2+1       summed = 20

p2 - 3   +    p2     +  p2-2    +   p2 + 1       = 20

4 p₂ -4 = 20

p₂ = 6              then p₄ = 7

The smallest possible radius is sqrt(a^2 + b^2).

4 is the answer
