Answer:

-20

Step-by-step explanation:

f(x) = 4x - 4

f(-4) = 4*-4 - 4

f(-4) = -16 - 4

f(-4) = - 20

  • f(x) shares many of the properties of y so you could think of this question as y = 4x - 4
  • The difference is as in this question that f(-4) conveys the message that wherever you see an x on the right side of the equation, you put -4 in it's place.
  • That's what was done on the second step.

What sum of money amounts to rupees 545 4 at 8% BA in 30 months​
Mars2501 [29]

Answer:

let sum of money be x

amount=rupees5454

rate=8%

time=30 months

convert month into year

30/12=5/2 years

Step-by-step explanation:

interest=p*t*r/100

=x*5*8/100*2

=40x/200

amount=principal +interest

5454=x+x/5

5454=5x+x/5

5454*5=6x

27270/6=x

4545=x

therefore ,sum of money(principal)=rupees.4545

A construction worker is tasked with tiling two square rooms, room A and room B. Room B has side lengths that are double the sid
swat32

Answer:

<u><em>4 boxes of tiles.</em></u>

Step-by-step explanation:

Both rooms are square, so each has equal sides.  Let's set a side to room A as x.  It's area would be x^2.  Room B has sides = 2x, so it's area would be (2x)^2 or 4x^2.  The ratio of the areas B/A = 4x^2/x^2.  B/A = 4.

Room B has 4 times the area of A.  If one box of tile completes Room A, Room B would need four times that amount, or 4 boxes.
