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 )
Sorry, don't have time to do them right now but I know who does!

Just plug in 2 at a time.
2x+3y=6
3y=-2x+6
3y/3=-2x+6/3
Y=-2/3x+2

Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
Step-by-step explanation:
You must spend at least $93 and no more than $100.
2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money
2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left
3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works
4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works
5 dress shirts: $105 too much money
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
