Answer:

Step-by-step explanation:

1)y=-6x-14   ---------(i)

-x-3y=-9  ---------- (ii)

Substitution method:

Substitute y  value in equ (i)

-x -3*(-6x-14) = -9

-x - 3*-6x -3*(-14)= -9

-x + 18x + 42 = -9

17x = -9 -42

17x = -51

x = -51/17

x = -3

Substitute x value in equation (i)

y = -6*-3 -14

y =18-14

y = 4

How do you factor 30n^2b-87nb+30b?
Rudik [331]
It's not clear whether you meant 30n^(2b) or [30n^2] b.

I will assume the latter.

b can then be factored out of all  three terms, resulting in 

b [30n^2 - 87n + 30]     = b [ 3 ] [10n^2 - 29n + 10 ]

Can you factor this further?

dsp73

Answer

Find out the  insurance company's payment .

To proof

Deductible

The deductible is the amount of money you will pay in an insurance claim before the company starts paying you insurance coverage .

As given

Sally Jones had a policy with a $250 deductible which paid 80% of her .covered charges less deductible

She had medical expenses of $18,240.00.

Amount becomes after deducting deductible = $18,240 -  $250

                                                                                   = $17990

80 % is written in the decimal form

now 80% of the Amount after deducting deductible

= $ 14392

Therefore $ 14392 is the insurance company's payment .
