Find the distance between two points. ENTER THE NUMBER THAT GOES BENEATH THE RADICAL SYMBOL.

iVinArrow [24]

<h2>The distance between two points is $\sqrt{98}$ or 9.9 units</h2>

Solution:

The distance between two points is given as:

$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$

From given,

$(x_1, x_2) = (-5, 5)\\\\(x_2, y_2) = (2, -2)$

Substituting the values we get,

$d = \sqrt{(2+5)^2+(-2-5)^2}\\\\d = \sqrt{7^2+(-7)^2}\\\\d = \sqrt{49+49}\\\\d = \sqrt{98}\\\\d = 9.899 \approx 9.9$

Thus the distance between two points is $\sqrt{98}$ or 9.9 units

Day and Night Kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Bark Time Hotel charges $30 per day plu

BaLLatris [955]

Answer:

See below.

Step-by-step explanation:

Let x represent the number of days.

Since Day and Night Kennel charges a fee of $20 per day and only a one-time fee of $15:

$y=20x+15$

Where y represents the total cost, 20x represents the cost for staying x days and 15 is the initial one-time fee.

For Bark Time Hotel, similarly:

$y=30x+5$

Again, y represents the total cost, 30x represents the cost for staying x days, and 5 is the initial one-time fee.

Thus, the system of equations is:

$y=20x+15\\y=30x+5$
