11. PLS help!!! the question is attached in the image below
Colt1911 [192]

Answer:

y = 3/2x-5/2

Step-by-step explanation:

We have two points so we can write the equation for the line. (-1,-4) and (3,2)

First we can find the slope by using

m= (y2-y1)/(x2-x1)

m = (2- -4)/(3 - -1)

   =(2+4)/(3+1)

   = 6/4

    = 3/2

Then put the slope into the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = 3/2x+b

We will use the point (3,2) and substitute it into the equation to find b

2 = 3/2(3)+b

2 = 9/2 +b

Subtract 9/2 from each side

4/2 -9/2 = 9/2-9/2 +b

-5/2 = b

y = 3/2x-5/2

James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be
Deffense [45]

Answer:

8.0%

Step-by-step explanation:

We have been given that James Harmon pays $850.80 per year for his life insurance. If Mr. Harmon were to pay the premiums monthly, the payments would be $76.57.

First of all, we will find the amount paid for the year using the monthly rate by multiplying $76.57 by 12 (1 year = 12 months).

\text{Amount paid for the year using the monthly rate}=\$76.57\times 12

\text{Amount paid for the year using the monthly rate}=\$918.84

Now, we will use percent change formula.

\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100

\text{Percent change}=\frac{\$918.84-\$850.80}{\$850.80}\times 100

\text{Percent change}=\frac{\$68.04}{\$850.80}\times 100

\text{Percent change}=0.0799717912552891\times 100

\text{Percent change}=7.99717912552891\%

\text{Percent change}\approx 8.0\%

Therefore, Mr. Harmon is paying 8.0% more for the year using the monthly rate.
