Distance between (2 , 3) (4 , -7)

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

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

d=\sqrt{(-10 )^{2} + (2 )^{2}

d=\sqrt{100 + 4

d=\sqrt{104

d=10.198 or 2\sqrt{26}

Find the slope of the line in simplest form.
N76 [4]

Answer:

-\frac{3}{2}

Step-by-step explanation:

To find the slope of the given line, slope is the rise divided by the run of a line.

  Slope  = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}  }

  Picking points (4, 18)  and (8, 12)

 Now;

  x₁  = 4

  y₁  = 18

  x₂ = 8

  y₂ = 12

  Slope  = \frac{12 - 18}{8-4}   = -\frac{6}{4}   = -\frac{3}{2}

Find two numbers whose sum is 64 and whose difference is 42
vovangra [49]
These numbers are  "a"  and "b".  
Sum is 64,  so  a+b=64
Difference  is 42  so  a-b=42
So you've got:
+\begin{cases} a+b=64 \\ a-b=42\end{cases} \\ \overline{, \quad2a \quad \ = \ 106} \qquad /:2 \\ a=53
When a+b=64 and a=53  you've got:
53+b=64
b=11

So these numbers is 53 and 11.

A rectangular prism has a volume of 96 ft3.the. Area of the base is 24 ft2.what is the height of the prism?
iren [92.7K]
H= 4 because volume of a prism is V=Bh and V=96 and B = 24 so it would be left as 96=24h So in order to find h we have to divide 24 by each number to find h alone so 24 divided by 24 equals 0 and 96 divided by 24 equals 4 so your answer is 4. Also, if you put the equation together after you find 4 you will see it all adds up. 96=24(4) which is correct
