Calib received $50 for his birthday and put it in his piggy bank. each week, he puts 2 more dollars in his bank. the amount of money in dollars d in his bank is given by
d = 2w + 50 where w is the number of weeks he has saved 2 dollars. his sister lara him find how much money he will have after 4, 15, 20, and 36 weeks. this table shows her results. what is the rate of change using lara's values for d and w? is this a linear model or non-linear model?

the rate of change varies. it is a non-linear model.

the rate of change is . it is a linear model.

the rate of change varies. it is a linear model.

the rate of change is 2. it is a linear model.

Option D)

The rate of change is 2. It is a linear model.

Step-by-step explanation:

Given that Calib received 50 dollars for his birthday.  To that he added every week 2 dollars.

D = 2w+50

We find that whenever a new week comes 2 dollars added to the piggy bank

Hence the rate of change of D for 1 increase in w is 2

The rate of change is 2. It is a linear model.

For any week we can calculate D

as D = 2(w)+50

If for 14 weeks

D=28+50 =78,

55? i think maybe

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
