Answer:
G (3,-4) ; H (8,1)
Step-by-step explanation:
Midpoint formula:
(x₁ + x₂ / 2 , y₁ + y₂ / 2)
For G (Points B and A):
(3 + 3 / 2 , 1 + (-9) / 2)
(6/2 , -8 / 2)
(3,-4)
For H (Points B and C):
(3 + 13 / 2 , 1 + 1 / 2)
(16 / 2 , 2 / 2)
(8,1)
Yes because that is what it is because that is the answer
18x-16y=5
Subtract 18x from each side
-16y=-18x+5
Divide by -16
y=18/16x-5/16
y=9/8x-5/16 this one is with improper fractions
Answer: 1.2metres
Step-by-step explanation:
Five years ago, tree was 4.9m
Today, tree is 6.1m
Subtract 4.9m from 6.1m
Tree has grown by 1.2m
In a quadratic equation
q(x) = ax^2 + bx + c
The discriminant is = b^2 - 4ac
We have that discriminant = 3
If
b^2 - 4ac > 0, then the roots are real.
If
b^2 - 4ac < 0 then the roots are imaginary
<span>In
this problem b^2 - 4ac > 0 3 > 0 </span>
then
the two roots must be real
