Answer:

\sqrt{17}\: units

Step-by-step explanation:

d =  \sqrt{ {(2 - 1)}^{2} + {(3 - 7)}^{2}   }   \\  \\ = \sqrt{ {(1)}^{2} + {( - 4)}^{2}   }  \\  \\ = \sqrt{ 1 + 16   }  \\  \\  d=  \sqrt{17}  \\

What is an equation of the line that passes through the point (-5, -6) and is
Vikentia [17]

Answer: y= 2x +4

Step-by-step explanation:

1. To be able to write the equation of the line, you want to be able to find the slope first. To do so, rearrange the given equation x+2y=2 into slope-intercept form, which is y=mx+b

First subtract x from both side, which will give us 2y=2-x. Rearrange this to get 2y= -x+2. Then, divide both sides by 2. This will give us y= -1/2x+1

2. Now that you have the equation, look for the slope in the new equation; this will be the m value. In this case, the slope is -1/2. Since we are looking for a line that is perpendicular, we have to change the slope so that it is the opposite reciprocal. The opposite reciprocal of -1/2 is 2, so the slope of the equation we want to find is 2.

3. Next, all we have to do is plug the given ordered pair (-5, -6) and the slope that we found (m=2) into the point-slope equation, which is y-y_{1} = m(x-x_{1} )

That will give us:

y+6 = 2(x+5)

4. Now, solve this equation.

y+6 = 2(x+5)  --> distribute the 2 inside the parentheses

y+6 = 2x + 10  --> subtract 6 from both sides

y= 2x +4

Solve the equation 1/2(16x – 6) = 2.
Lorico [155]

Answer:

x = 0.625 or 5/8

Step-by-step explanation:

1/2(16x-6) = 2

8x - 3 = 3

8x = 3 + 3

8x/8 = 9/8

x = 0.625
