Answer:
Step-by-step explanation:
Mixed fraction 
can be converted into like or unlike fractions.
Here, 
So, convert all the given fractions as follows:
Here, No Two fractions on addition gives a sum greater than 5.
But an approximate sum of 5 is given by adding 2.4 + 2.6 = 5
⇒
or ⇒
Answer:
4
Step-by-step explanation:
48 divided by 12 is 4 simple division
A. Blue: y = -3x + 8
Black: y = 3x + 2
B. You find the ordered pair (x, y) that is a solution for both functions ( find the point where the two lines cross)
C. There’s two ways you can solve algebraically (using the equations); substitution and elimination. I don’t know which you need to use to answer but feel free to use my notes on how to do substitution for help. I don’t really have any on elimination ( it’s so easy you don’t even really need notes) or I would use them to explain.
2 and 1/5

Ok, so for parabola a(x-h)^2 +k
abs(a) = 1/(4c) where c is the distance between the focus and directrix.
The distance is 4-1, or 3 (y coord of the focus - y coord of directrix)
so a = 1/(4*3) or 1/12
and the vertex (h,k) is the midpoint of the segment between the focus and directrix, which is (1, 2.5)
the parabola is 1/12*(x-1)^2 + 2.5
