When you divide a whole number by a whole number( other then one), the quotient is a smaller number?

Yes because division always makes numbers smaller. For example: 12 divided by 4 equals 3.

Find the distance between (2,7) and (-6,-2)
stepladder [879]

Answer: \sqrt{145}

Step-by-step explanation:

1. use the distance formula!

distance = \sqrt{(x_{2} - x_{1})^{2}  +{(y_{2} - y_{1})}^2

2. then using the distance formula with (2, 7) and (-6, -2) you get...

distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}

distance= \sqrt{8^2 +9^2}

distance=  \sqrt{64 +81}

distance= \sqrt{145}

\sqrt{145} is the simplest radical form

Solve for the variable b. 5a(b - c ) = d
Liula [17]
5a(b-c)=d. Here, we are trying to isolate the variable b.
Divide both sides by 5a: b-c=d/(5a)
Add c to both sides: b= \frac{d}{5a} +c

Tell whether the lines through the given points are parallel, perpendicular, or neither?
Paha777 [63]

Slope\,\,1=\frac{-1}{slope\,\,2}

So, Both lines are perpendicular

Step-by-step explanation:

We need to identify if lines:

Line 1: (8,12)(7,-5)

Line 2: (-9,3)(8,2)

are parallel, perpendicular, or neither?

  • Lines are parallel if they have same slopes i.e slope 1= slope2
  • Lines are perpendicular if their slopes are negative inverses of each other i.e slope 1= -1/slope 2

The formula used to find slope is:

Slope=\frac{y_2-y_1}{x_2-x_1}

Finding Slope of Line 1:

The points are: Line 1: (8,12)(7,-5)

x_1=8, y_1=12, x_2=7,y_2=-5

Putting values in the formula:

Slope\,\,1=\frac{y_2-y_1}{x_2-x_1}

Slope\,\,1=\frac{-5-(12)}{7-8}

Slope\,\,1=\frac{-5-12}{-1}

Slope\,\,1=\frac{-17}{-1}

Slope\,\,1=17

So, Slope of line 1 is 17

Finding Slope of Line 2:

The points are: Line 2: (-9,3)(8,2)

x_1=-9, y_1=3, x_2=8,y_2=2

Putting values in the formula:

Slope\,\,2=\frac{y_2-y_1}{x_2-x_1}

Slope\,\,2=\frac{2-(3)}{8-(-9)}

Slope\,\,2=\frac{2-3}{8+9}

Slope\,\,2=\frac{-1}{17}

So, Slope of line 2 is \frac{-1}{17}

Since Slope\,\,1=\frac{-1}{slope\,\,2}

So, Both lines are perpendicular
