Find the distance between the two points (-10,3) and (0,27)

crimeas [40]

Answer:

26 units

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above,

distance between (-10, 3) and (0, 27)

$= \sqrt{ {( - 10 - 0)}^{2} + {(3 - 27)}^{2} }$

$= \sqrt{ {10}^{2} + ( - 24) {}^{2} }$

$= \sqrt{100 + 576}$

$= \sqrt{676}$

= 26 units

Which situation can be represented by the equation y = 12 x ?

Marat540 [252]

Answer:

Let's solve for x.

y=12x

Step 1: Flip the equation.

12x=y

Step 2: Divide both sides by 12.

12x /12 = y /12

x= 1 /12 y

Answer: x= 1 /12 y

Step-by-step explanation: Hope this helps :D
