The answer is -1 because using the trick rise/run from one point to the next proves it
Answer:
Step-by-step explanation:
we have
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to 
In this problem we have the axis of symmetry 
so
the x-coordinate of the vertex is equal to 
therefore
For 
-----> one unit to the right of the vertex
Find the value of 
For 
-----> one unit to the left of the vertex
Find the value of 
Remember that
------> the x-coordinates are at the same distance from the axis of symmetry
so
------> solve for b
Answer:
Step-by-step explanation:
The circumcenter is equidistant from the three vertices of the triangle. From the figure shown, we will prove DA = DB = DC. 2) DA = DB, DC = DB(If a point is on the perp. bisector of a segment, it is equidistant from each endpoint of the segment.)
Answer:
The budget line will remain unchanged.
Step-by-step explanation:
A budget line helps in showing the possible combinations of two commodities.
We can find the slope of the budget line that is also called the price ratio between two things. If we get a straight line, we say the slope is constant.
Here in the question its given that the initial constraints are (3,15) with initial income of $60. Then the price increases and constraints become (6,30) with an increase in income up to $120.
Therefore, the budget line will not be affected and remain unchanged as each constraint is doubling and the slope will be constant.
