Answer:

1

Step-by-step explanation:

So since both equations equal f(x), we can set them equal to each other

-15x - 13 = -28

Our next step is to get x by itself on one side of the equation. To do this, you:

Add 13 to both sides

-15x = -15

Divide both sides by -15

x = 1

if a sum of money increased by 1/5 of itself every year and in 5 years amounts to Rs.8546,find the sum
weqwewe [10]

Answer:

Answer :

Given  : If a sum of money amounts to Rs 2200 in 5 years

Let sum of money =  x

And as given : The interest is 3838 of the principal . So we get

x ( 3838 ) = 2200 - x

3x  =  17600 - 8x

11x  =  17600

x   =  1600

So, Sum of money  =  Rs . 1600

Then interest =  2200 -  1600 =  Rs . 600

Let Rate of interest  = r  %

And we know Simple interest  = P × r × t100P × r × t100 , So we get

⇒1600 × r × 5100 =  600⇒16× r × 5100 =  6⇒80r  =  600⇒r = 60080 = 152 =  712%⇒1600 × r × 5100 =  600⇒16× r × 5100 =  6⇒80r  =  600⇒r = 60080 = 152 =  712%

So
