Answer:
Step-by-step explanation:
x+y = 6
y = (6-x)
7x +12y = 52
7x+12(6-x) = 52
7x +72 -12x = 52
-5x = -20
x= 4 4 days at $7 = $28
2 days at $12 = $24
28+24 = 52
Answer:
No, I do not agree with the conjecture because 1 is not a prime number.
Step-by-step explanation:
A prime number is one that can be divided by 1 and itself only. Thus it can be expressed in 2 factors only, 1 and the number itself.
Examples are; 2, 3, 5, 13, 19 , 23 etc.
So, 2 = 1 x 2
3 = 1 x 3
23 = 1 x 23
Prime numbers must be expressed as the product of 1 and the number.
The conjecture that every prime number can be expressed as the product of two prime numbers is false. Because 1 is not a prime number, since it has no 2 factors.

Answer:
{x,y}={5,4} x is =5 y= to 4
Answer:
(2,-9)
Step-by-step explanation:
Set the quadratic equal to zero.
Factor
Set each of these factors to zero
and
and
Plot the midpoint of the two values.
So the middle term is 2 and the other terms are 5 and -1.
Now the vertex is
So the vertex is
(2,-9)
