Let r be the lesser root and r^2 be the greater.......the sum of the roots = -b/a = -[-6] / 1 = 6
So we have that
r^2 + r = 6 → r^2 + r - 6 = 0
Factor
(r + 3) (r - 2) = 0
So r = -3 or r = 2
Then r^2 = 9 or r^2 =4
And the product of the roots = c/a = k/a = k
So....k = (-3)(9) = -27 or k = (2)(4) = 8
Check
x^2 - 6x - 27 = 0 factors as (x + 3)(x - 9) = 0 and the roots are -3 and 9
x^2 - 6x + 8 = 0 factors as (x -2) (x - 4) =0 and the roots are 2 and 4
Answer:
3/5 and 250 the number of girls is 150
Step-by-step explanation:
Answer:
B as we start with X intercept =0
Step-by-step explanation:
x= 10 x 6 = 60
(v= 1/6x = 6x x 10y) x= 60v
y=10
When x=0 then y = 0 when x= 10 we have 10 minutes each count
So the graph will go up by 10 to 60 on the x axis.
value of nickle=6 and units of 10 nickles have value of 60
But this is a measure of time using nickles for x.
and measure of quarters can then show a pattern of zero each time. y=mc+x = 0 when y=0 = y=1x0+0 when x =6 and y=0
