Ответ:
r+g+y=33
r=3g
2y=r
substitution:
y=33-g-r
y=33-(1/3)2y+2y
y=33-8/3y
11/3y=33
y=33÷(11/3)
y=9
Solve for red and green:
r=2y
r=2×9
r=18
3g=r
3g=18
g=18/3
g=6
double check:
6+18+9=33
6 green apples, 9 yellow apples and 18 red apples.
Ответ:
a= -4 , b= 4 , c= -1
Plug in into your formula
(4)^2-4(-4*-1)
16-16
x=0
so the solution only has one x-intercept
