Answer:

x=-6

Step-by-step explanation:

1. Collect like terms [-15x] [+6x]

-15x+10+6x=64

-9x+10=64

2. Move constant [+10] to the right-hand side and change its sign

-9x+10=64

-9x=64-10

3. Subtract the numbers [64-10]

-9x=64-10

-9x=54

4. Divide both sides of the equation by -9

-9x/9=54/9

5. Solution

x=-6

20 POINTS !!! <br><br> Find the distance between the points (3,-4) and (5, 4)

jeka57 [31]

Answer:

$d=2\sqrt{17}\approx8.2462$

Step-by-step explanation:

To find the distance between two points, use the distance formula.

The distance formula is:

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

Let (3,-4) be x₁ and y₁ and let (5,4) be x₂ and y₂. Therefore:

$d=\sqrt{(5-3)^2+(4--4)^2$

Simplify:

$d=\sqrt{(2)^2+(8)^2$

Square:

$d=\sqrt{4+64}$

Add:

$d=\sqrt{68}$

Simplify:

$d=\sqrt{4\cdot17}=\sqrt4\cdot\sqrt{17}$

Simplify:

$d=2\sqrt{17}\approx8.2462$
