Answer:

a=2

Step-by-step explanation:

Slope is found by (y2-y1)/(x2-x1)

Using the points, that is (5-a)/(4a-2) = 1/2

multiply both sides by the denominator 4a-2

5-a = (1/2)(4a-2)

5-a=2a-1

put like terms on opposite sides by adding a to both sides so a terms on the right, adding 1 on both sides so numbers are on the left

6=3a

divide both sides by 3

a=2

please give thanks :)

Laura bernett is 5 ft-4 inches tall. she stands 12 feet from a streetlight and casts a 9-foot-long shadow. how tall is the stree

xxMikexx [17]

The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches

The streetlight is 12 ft 5 1/3 inches tall.

Does anyone know how to simplify? 5y(2y-3) + (2y-3) = ?

mamaluj [8]

Hey there!!

The given equation :

... 5y ( 2y - 3 ) + ( 2y - 3 )

Let's write this as ...

... 5y ( 2y - 3 ) + 1 ( 2y - 3 )

Now, if we take ( 2y - 3 ) as a common term, we get...

... ( 5y + 1 ) ( 2y - 3 )

Hence, the correct answer would be option ( A )
