Answer:
-6/5
Step-by-step explanation:
by using the y2-y1/x2-x1 formula we can calculate the slope as -6/5 you could also just see that the line goes 6 down and 5 to the right and have gotten the same awnser
The total amount of blue glass was=(2/3)*(30 9/10)=
=(2*30)/3 (9*2) /(10*3)=60/3 18/30=20 3/5.
The answer is 20 3/5
Congratulations!! you are right!
The Discriminant = b²-4ac
1.
a=2
b= 5
c=-3
The Discriminant is 49
When a, b and c are real numbers, a ≠ 0 and discriminant is positive and perfect square, then the roots α and β of the quadratic equation ax2 + bx + c = 0 are real, rational unequal.
2.
a=-1
b=1
c=1
The Discriminant is 5
When a, b and c are real numbers, a ≠ 0 and discriminant is positive but not a perfect square then the roots of the quadratic equation ax2 + bx + c = 0 are real, irrational and unequal.
3.
a=1
b=6
c=11
The Discriminant is-8
then the roots α and β of the quadratic equation ax2 + bx + c = 0 are unequal and imaginary.
4.
a=9
b=-54
c=81
The Discriminant is 0
the roots α and β of the quadratic equation ax2 + bx + c = 0 are real and equal.
