Answer:
p = 8
Step-by-step explanation:
Let one root of the eqn. be alpha . Other root is 1/alpha .
We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant & "a" is the co-efficient of x^2.
Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

A would equal 4 because you would first convert the mixed numbers into improper fractions, then move the constant to the right, and finally add the factions
a-2(1/2)=1(1/2)
a-(5/2)=(3/2)
a=(3/2)+(5/2)
a=4
Answer:

Step-by-step explanation:
If you were to replace x with 0 in each of the equations, you would get
from top to bottom choices:


2
-2
Since we can see that the line touches the y-axis on the number -2, we know that it is the last choice that is the answer
