7 is the GCF of 21a and 28y
Step-by-step explanation: they both can be divided by 7!
7(21a/7 + 28y/3) = 7(3a + 4y)
the slash is a division symbol!
30÷100= 0.38
0.38×25= 9.5
9.5 miles is what they should hike the first day.

Given:
Consider the quadratic function is
With given vertex (5,8) and given point (1,3).
To find:
The equation of quadratic function.
Solution:
The quadratic function is
...(i)
Where, (h,k) is the vertex and a is a constant.
Vertex is (5,8). So,
Putting in (i), we get
...(ii)
The given point is (1,3). Putting x=1 and y=3 in (ii), we get
Putting in (ii), we get
Therefore, the required quadratic function is .
