OverLord2011 [107]

Answer:

Step-by-step explanation:

I will use substitution

We will substitute the answer for y into the bottom equation

x+(4x+3)=-2

5x+3=-2

5x=-5

x=-1

Now solve for y

(-1)+y=-2

y=-1

Write as an ordered pair

Find the distance between the two points in simplest radical form.<br> (7,2) and (-1, -3)

Paul [167]

Answer:

The answer is

<h2> $\sqrt{89} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(7,2) and (-1, -3)

The distance between them is

$d = \sqrt{( {7 + 1})^{2} + ({2 + 3})^{2} } \\ = \sqrt{ {8}^{2} + {5}^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{89} \: \: \: \: units \\$
