Answer:

The answer is - No the relation is not proportional.

Step-by-step explanation:

A restaurant charges $5 for one sandwich, $9.90 for two sandwiches, and $14.25 for three sandwiches.

No, the rates are not proportional.

The unit rate is $5 per sandwich.

So, for being proportional, the rates should have been like $10 for 2 sandwiches and $15 for 3 sandwiches.

Answer:

2 Real Roots

Step-by-step explanation:

The discriminant (D) is found using the formula b^2+4ac for the equation ax^2+bx+c.

If D>0 there are two real roots, D=0 one real root and D<0 no real roots.

D = b^2+4ac

D = 10^2+4(-4)(-8)

D = 100+32*4

D = 100+128

D = 228

since 228>0

There are 2 real roots
