Solve using substituion -5x + y = -2 -3x + 6y = -12
sergiy2304 [10]

Answer:

<h2>x = 0</h2><h2>y = - 2</h2>

Step-by-step explanation:

-5x + y = -2………… Equation 1

-3x + 6y = -12 ………… Equation 2

Using substitution

Make y the subject in equation 1 and substitute it into equation 2 and solve for x

That's

y = 5x - 2

We have

- 3x + 6( 5x - 2) = - 12

- 3x + 30x - 12 = - 12

27x = - 12 + 12

27x = 0

Divide both sides by 27

x = 0

Substitute x = 0 into y = 5x - 2

We have

y = 5(0) - 2

y = - 2

So the solutions are

<h3>x = 0 </h3><h3>y = - 2</h3>

Hope this helps you

Find the distance between the two points rounding to the nearest tenth (if necessary)
Andrews [41]

Answer:

The answer is

<h2>2.8 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

(-3,3) and (-1,5)

The distance is

d =  \sqrt{( { - 3 + 1})^{2} +  ({3 - 5})^{2}  }    \\  =  \sqrt{ ({ - 2})^{2} + ( { - 2})^{2}  }  \\  =  \sqrt{4 + 4}  \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \\  = 2.82842

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you
