Which equation represents a non proportional relationship?


A y = 3x + 5
B y = −3x
C y = 1/3x
D y = 3x + 0

Answers

Answer:

A

Step-by-step explanation:

The answer is A because in order for a relationship to be proportional, it must go through the origin, or (0,0). This means that all proportional relationships have a y-intercept of 0 because there is no initial value. A is the only answer choice that has a y-intercept that is not 0.

It’s A. It’s doesn’t go through the origin

Arisia puts $500 into a savings account with an annual simple interest rate of 4.5%. If the interest rate stayed the same, how much money would be in Arisia’s account after 20 years?

Answers

She would have $10,450

Answer:

$112.5

Step-by-Step Explanation:

Step one:

given data

principal= $500

rate= 4.5= 0.045

time t= 5years

Step two:

the expression for the simple interest is given as A=P(1+rt)

the interest SI= final amount (A)- Principal(P)

Substituting we have

A=500(1+0.045*5)

A=500(1+0.225)

A=500(1.225)

A=612.5

the interest is 612.5-500

=$112.5

Naomi works in a music shop and earns $42 per day. She earns an extra $2 for each CD she sells. If Naomi wants to earn at least $80 per day, which inequality shows the minimum number of CDs, n, that she should sell? (10 points)

42 + 2n ≤ 80, so n ≤ 19
42 + 2n ≥ 80, so n ≥ 19
42 + 2n ≥ 80, so n ≥ 36
42 + 2n ≤ 80, so n ≤ 36

Answers

Answer:

42 + 2n ≥ 80, so n ≥ 19

Step-by-step explanation:

Naomi's earnings for one day = $ 42,

Also, she earns extra $2 for each CD she sells,

Thus, the extra earning for n CDs = 2n dollars,

So, her total earning for a day if she sells n CDs = ( 42 + 2n ) dollars,

If Naomi wants to earn at least $80 per day,

Her total earning ≥ 80 dollars,

Answer:

First. 42 + 2n ≥ 80, so n ≥ 19

Step-by-step explanation:

Because you see at least $80 so its just less or same 80. ANd we need to find the minimum number of CDs, but 36 is big, I choose 19.
