The answer to the question
<span>2p + q = 1
9p + 3q + 3 = 0
q = 1 - 2p
replace </span>q = 1 - 2p into 9p + 3q + 3 = 0
9p + 3(1 - 2p) + 3 = 0
9p + 3 - 6p + 3 = 0
3p + 6 =0
3p = -6
p = -2
q = 1 - 2p
q = 1 -2(-2)
q = 1 + 4
q = 5
(-2 , 5)
answer
<span>{(-2, 5)} first one</span>
It would be C.
For example, say 1 person comes. This would be x=1. Plugging this in gives you,
y=0.5 + 1.3
This shows that C is true since x is always going to be multiplied by 0.5.
1.3 would be the base amount of time it takes to arrange since if it the y-intercept.
No because when ever you multiply the same reciprocals you always end up with the number 1
Remark
A function is defined as 1 y value per x value. The y values can be the same for 2 x values, but the x values must have just 1 value associated with it. I am describing a vertical line test for a function. This is a function.
A 1 to 1 function means that the function obeys the horizontal line test. That means that for every x there is only 1 y value.
A
This graph is both a function and a 1 to 1 function. So the answer is A.
None of the other answers are this complete and one of them is wrong.
B
B is wrong. It is a 1 to 1 function.
C
C is wrong. The graph is a function.
D
D is wrong. No y values are duplicated.
