Answer:
a = 1/25
Step-by-step explanation:
The vertex form of the parabola is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a(x-2)^2 -4
We have a point on the parabola (-3,-3) so substitute this into the equation
-3 = a(-3-2)^2 -4
-3 = a(-5)^2 -4
Add 4 to each side
-3+4 = a(25) +4-4
1 = 25a
Divide each side by 25
1/25 = a
y = 1/25(x-2)^2 -4
Answer:
m=-3 b=6
Step-by-step explanation:
3y= -6x + 9
divide everything by 3
y=-3x+6
m=-3 b=6
Answer:
The answer is No, according to the Triangle Theorem.
Step-by-step explanation:
When you have the sides of the triangle, you must be able to add up 2 sides and have a larger number than the other side.
4+5 = 9 which is greater than 1
5+1 = 6 which is greater than 4
4+1=5 which is equal but not greater than 5
Answer:
Yes
Step-by-step explanation:
The answer using distributive property is the same as using original way to caculate it.
3+5(2+4) = 3+5(6) =3+20 =33
