Answer:
4/25
Step-by-step explanation:
D they all have the same slope.
To solve this, you can first solve each expression:
35 / 6 = 5.83333
5 + 3/10 = 5.3
5 = 5
35 / 10 = 3.5
15 / 5 = 5
5 + 5/6 = 5.8333333
3 = 3
10 * 1/2 = 5
So, the tiles of 5, 15*1/5, and 10*1/2 all equal 5.
The tiles of 35/6 and 5+5/6 equal 5.83333.
The remaining tiles to not have matches.
A second degree polynomial function has the general form:

, where

.
The leading coefficient is a, so we have a=-1.
5 is a double root means that :
i) f(5)=0,
ii) the discriminant D is 0, where

.
Substituting x=5, we have
f(5)=a(5)^2+b(5)+c,
and since f(5)=0, and a is -1 we have:
0=-25+5b+c
thus c=25-5b.
By ii)

.
Substituting a with -1 and c with 25-5b we have:
Finally we find c: c=25-5b=25-50=-25
Thus the function is

Remark: It is also possible to solve the problem by considering the form

directly.
In general, if a quadratic function has leading coefficient a, and has a root r of multiplicity 2, then its form is
