Answer:

15.2 mph

Step-by-step explanation:

2.4÷(x+4)=1.4÷(x-4)

1.4(x+4)=2.4(x-4)

1.4x+5.6=2.4x-9.6

-x=-15.2

x=15.2

Hope this helps!

Point A is at (-7, -9) and point M is at (-0.5, -3).
Anit [1.1K]

Answer:

<em>B ( 6 , 3 ) </em>

Step-by-step explanation:

( x_{1} , y_{1} )

( x_{2} , y_{2} )

Coordinates of midpoint are ( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

~~~~~~~~~~~~~~~~~~

A ( - 7 , - 9 )

B ( x , y )

M ( - 0.5 , - 3 )

\frac{-7+x}{2} = - 0.5 ⇒ <em>x = 6</em>

\frac{-9+y}{2} = - 3 ⇒ <em>y = 3</em>

<em>B ( 6 , 3 )</em>
