Answer: B) False

The input x = 5 leads to the two outputs f(x) = 2 and f(x) = 1 (as shown by the green arrows in the attached image). In order to have a function, all of the inputs must lead to exactly one output.

Its False...because functions can put in more than one real numbers but the output can only have 1 possible number and in this the number 5 input has 2 outputs!!

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.

5x + 2y = 8

notsponge [240]

Multiply the equation x+y =4 by -5
The resultant would be-
-5x -5y = -20
Adding this with 5x +2y =8
Then, the resulting would be,
-3y = -12
∴ y=4
and x=4-4 =0
