Answer:

X=2.5

Step-by-step explanation:

Triangle ABC = Triangle DEF

So if we flip the triangle ABC over the x-axis,( Turn it 180 degrees using any given point,[A, B, or C])

,you get the same triangle as DEF.

Adding all the sides on triangle ABC, it equals 3x+10.

Triangle DEF doesn't have the luxury of having all sides labled but since ABC=DEF, we can use the sides x+4 and x+6 to get 2x+10 for both of the unlabled sides combined. Finally, we can combine 2x+10 and 3x-5 to get a total of 5x+5 for triangle DEF.

So 3x+10=5x+5. Doing simple isolation,(subtract 5 from both sides, then subtract 3x from both sides, divide by 2 on both sides), you get X=2.5.

Answer:

(4,2). DEPENDENT

Step-by-step explanation:

As each equation consist on two variable, both can be represented graphically on a cartesian plane. First, each expression is rewritten in explicit form:

$y = 6 - x$ (red line) and $y = x - 2$ (blue line)

By the resource of graphing software, the solution is (4,2). The representation is presented below as attachment. As solution exists, both expression are linearly DEPENDENT.

Tina has 1/4 of a cake. He divides it between his 6 friends. How much of the whole cake will each friend get?

klemol [59]

As Tina only has 1/4 of a cake. For simplicity sake we can do the calculation with a whole cake and then multiply by four!

First it is stated that cake is divided into six pieces, giving us our first number.
So,

6 x 4 = 24

This means that each friend will get 1/24th of the whole cake.

Answer:

Step-by-step explanation:

Dividend policy (hypothesis) of firms as stated by Musa (2009) is a cultural phenomenon that changes continuously according to environment and time, hence it is necessary to continuously modify dividend behavioural models to capture those factors that are peculiar to a particular period and environment, as well as changes in tax.
