When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck

You can solve for X by simplifying both sides of the equation then isolating the variable x=1.533396 , 1.30336

Real numbers x and y satisfy x + xy^2 = 250y, x - xy^2 = -240y. Enter all possible values of x, separated by commas.

agasfer [191]

Answer:

-35,35,0

Step-by-step explanation:

Let's organise our information :

x+xy²=250y
x-xy²= -240y

Now let's add them together :

x+xy²+x-xy²=250y-240y
2x=10y
x=5y ⇒ y= x/5

Let's replace y by x/5 in the first equation :

x+x*(x/5)²=250*(x/5)
x+ (x∧3)/25 = 50x
49x-(x∧3)/25=0
x(49-(x²/25))=0
x=0 or 49-(x²/25)=0
x=0 or 49= x²/25
x=0 or x²=1225
x=0 or x= $\sqrt{1225}$ or x= - $\sqrt{1225\\}$
x=0 or x=35 or x= -35

so x=[0,35,(-35)]

Taggart transcontinental has a dividend yield of 2.5% .Taggarts equity cost of capital is 10% and its dividends are expected to

Arisa [49]

Answer:

D) 7.5%

Step-by-step explanation:

Using dividend growth model,

Price, P = D / (r - g)

where, D = Dividend, r = cost of equity = 10% , and g= growth rate

we know that

=> r - g = D / P = Dividend yield = 2.5%

=> Growth rate, g = 10% - 2.5% = 7.5%

therefore the constant growth rate in dividends is closest to= 7.5%
