I will solve your system by substitution.x=−2;y=23x+3Step: Solvex=−2for x:Step: Substitute−2forxiny=23x+3:y=23x+3y=23(−2)+3y=53(Simplify both sides of the equation)

Answer:x=−2 and y=5/3

so the answer is B (the second choice)
(Hope it helped ^_^)

Find the distance between each pair of points. Round your answer to the nearest tenth. (-6, -5) and (2, 0)

Anna71 [15]

Answer:

The answer is

<h2>9.4 units</h2>

Step-by-step explanation:

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

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

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

From the question the points are

(-6, -5) and (2, 0)

The distance between them is

$d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 8})^{2} + ( { - 5})^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \: \\ = 9.4339811$

We have the final answer as

<h3>9.4 units to the nearest tenth</h3>

Hope this helps you
