The answer would be B. Because 4/10 = 0.4, which is what you would multiply 50 by to find sales tax.
Answer:
OR
Step-by-step explanation:
Vertex form of a parabola is given as:
Where () is the vertex and are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
First of all, putting the vertex in the vertex equation as given above:
Now, putting the values of as 2, 3 and let us find the unknown variable :
Therefore, the equation in vertex form can be written as:
OR
no u ,...................................................................................................................................
I’m not sure so I’m gonna take an educated guess. I think it’s 1/3x
Answer:
1. Take a=4, b=6
a+b
=4+6
=10( Both are positive integers)
2. a=4 , b= -6
then 4 + (- 6)
= 4 - 6
= -2 [Smaller is positive integer and larger is negative integer , So subtract smaller from larger and apply the sign possessed by larger integer]
3. a = -4, b= -6
a+ b
= -4 -6
=-10 [ Both are negative integers add them apply - sign before the number.]
4. a = -4, b=6
a +b
= -4+ 6
= 2 [one is positive and other is negative subtract smaller from larger and apply positive sign before the number.]
