Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent
docker41 [41]

Answer:

Please specify what the three expressions are.

Step-by-step explanation:

From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:

2(x-3)=2x-6

Then, by evaluating it, you would get:

2x-6=2x-6 by distribution over subtraction.

2x-6+6=2x-6+6 by the additive property of equality

2x=2x Simplify.

x=x by the reflexive axiom.

Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.

Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.

Sorry I could not be of more help, but you did not specify what the expressions were.

H.<br> R(x) = kx – 2x^2 ; R(1/4)<br> R(-1/4)<br> find k.
True [87]

Answer:

k=0

Step-by-step explanation:

R(x)=kx-2x²

R(1/4)=k(1/4)-2(1/4)²=k/4-1/8

R(-1/4)=k(-1/4)-2(-1/4)²=-k/4-1/8

R(1/4)=R(-1/4)

k/4-1/8=-k/4-1/8

k/4+k/4=1/8-1/8

2k/4=0

2k=0

k=0

Which table shows a proportional relationship between x and y?
oksano4ka [1.4K]
The top one. Think about the difference between each one: X goes from 1 to 2 and Y goes from 5 to 10. Each number you go up, Y increases by 5. This means there is a proportional relationship.
