First-person to answer with an Explanation get Brainliest Every package of a certain toy also includes 2 batteries.

1. Are the number of toys and the number of batteries in a proportional relationship? If so, what are the two constants of proportionality? If not, explain your reasoning.
2. Use t for the number of toys and b for the number of batteries to write two equations relating the two variables.
b=

t=

1) Yes, 1/2 and 2

2) b=1/2 × t

t=2 × b

Step-by-step explanation:

1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)

2) b = 1/2t, because for every battery, there is 1/2 a toy.

t = 2b, because for every toy, there are 2 batteries

note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
