Answer:
A
Step-by-step explanation:
because absolute value is always positive as the answer and it's a because 4 is already a positive so it will be a positive again
Answer:
5"
Step-by-step explanation:
You are copying a square of side 20 inches into a smaller version of it that is exactly 25% of the original size.
Notice that 25% can be written in fraction form as: 
This gives us a clue about how to reduce the original dimension: "multiply it by
, which is the same as divide it by 4:

Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
The expression given by f(x)=a(x-h)^2+k is a the equation of a vertex where (h,k) is the vertex. The importance of h is that it represents the x-intercept, the lowest or the highest point of the graph of the expression. This is a very important factor when determining the turning points of parabolas
