Answer:

The statement is true.

Step-by-step explanation:

Let the two points are (x', y') and (x'', y'').

The equation of line passing through the two  points is

(y - y')=\frac{y''-y'}{x''-x'}\times (x - x')

So, it is true to find the equation of line when the two points is given.

kompoz [17]
A pentagon has 5 sides.
A hexagon has 6 sides.
If the pentagon has 5 sides that each measure 6 inches, then the perimeter would be 30 inches.
If the hexagon has 6 sides that measure 5 inches each, then the perimeter is also 30.
The shapes have the same perimeter.

Each time Kristine gets paid, she spends $20 and saves the rest. If the amount Kristine earns is represented by x and the amount
kenny6666 [7]

Answer:

A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

Step-by-step explanation:

If Kristine spends $20 and saves the rest when she gets paid, the amount she saves should always be 20 less than the amount she earned.

The points (20, 0) and (25, 5) accurately represent this, where x is how much she earns and y is how much she saves.

(20, 0) represents her earning $20 and saving $0, because she spends $20 every time she gets paid.

(25, 5) represents her earning $25 and saving $5, because she spent $20.

So, the correct graph is A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

The formula for compound interest is:
sveta [45]

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 500(1 + \frac{0.05}{365})^{365*5}

A = 500(1 + 0.000137)^{1825}

A = 500(1.000137)^{1825}

A = 500*1.2840

Future value, A = $642
