The constant of proportionality (r) appears to be 3.
y = 3x . . . . . . . x = number of tickets sold; y = dollars collected
3i is not equivalent to 3 because i is representative for the square root of -1. In reality it is 3(square root of -1) and 3 .
You’re trying to get the first equation to equal y so you can substitute it in the second question
2x + y = -2
subtract 2x from both sides: y = -2 - 2x
rearrange the equation : -2x -2
so the answer is C
Answer:
The correct option is commutative property.
Step-by-step explanation:
The expression that Renee is simplifying is:

It is provided that, Renee recognizes that 7 and
are reciprocals, so she would like to find their product before she multiplies by
.
The associative property of multiplication states that:

The commutative property of multiplication states that:

The distributive property of multiplication states that:

The identity property of multiplication states that:

So, Renee should use the commutative property of multiplication to find the product of 7 and
,

Thus, the correct option is commutative property.
Answer:
-25
Step-by-step explanation:
h(j) = -j^2-6j+2 Let j =3
h(3) = -3^2-6(3)+2
= -9 -18+2
= -27+2
= -25
