What of b make y = 2x plus b the same as y=2x? What does that value mean?
WITCHER [35]

Answer:

No

Step-by-step explanation:

The short answer is no. b stands for some number. Once that number is fixed, it does not change. So the equation would look something like

y = 2x + 6  Now if you look at that again, that 6 is fixed.

If you want to put something in for x like x = 5 you get

y = 2(5) + 6

y = 10 + 6

y = 16                   b = 6 did not change.

What does y = 2x equal

y = 2*5

y = 10

10 does not equal 16.

The only exception to what I've written is b = 0. Then both equations mean the same thing. But that is an exception.

Stephanie has a homeowners insurance policy for her $355,000 home with an annual premium of $0.42 per $100 of value and a deduct
lapo4ka [179]

The annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.

<h3>What is an insurance premium?</h3>

Insurance premiums are paid for policies that cover all the basic needs such as healthcare, home, and life insurance.

We are given Amount of insurance policy for Stephanie = $ 355,000

Annual premium = $ 0.42 per $100

Deductible amount = $ 500

Total Annual out of pocket expense

= [($355,000/100) x $0.42] + $500

= $1,991  

Now, the New Deductible amount that Stephanie wants is $ 1000

So, Let the annual premium be x

To find the annual premium in an annual out-of-pocket expense that is about the same as her current plan when the deductible amount increases to $1000

355,000x / 100 + 1000 = 1991

3550x + 1000 = 1991

3550x = 1991 - 1000

3550x = 991

x = 991/3550

x = 0.279≈0.28

Hence the annual premium result in an annual out-of-pocket expense that is about the same as her current plan is $0.28 per $100 of value.
