As of today, the exchange rate was one British Pound is worth 1.32 American dollars. That means that if you go to the Bank of England and hand them a 10 pound note (is there such a thing?), you will get 13 dollars and 20 pennies (American) back.
So here's the formula
American money = British pounds * 1.32.
Step-by-step explanation:
In this case you know that the segment BC was dilated from the origin, producing the image B'C', whose endpoints are:
The image BC was dilated with a scale factor of 2. This means that each coordinate of the endpoints of BC was multiplied by 2.
Therefore, you can conclude that the segment BC is one-half the size of the segment B'C'.
So, you can divide each coordinate of B' and C' by 2 in order to find the coordinates of the points B and C.
Then:
B→
C→
1)first step
for the first inequation you need apply the following property, IXI < a
-a<x<a, them you must substitute 2x-3, of this form
-5<2x-3<5⇒ -5+3<2x-3+3<5+3⇒-2<2x<8⇒-2/2<2x/2<8/2⇒ -1<x<4,
the solution is
S1 =(-1,4)
2) For the second inequality apply the following property
IXI>a , x<-a or x >a , therefore
IX-2I>1 ⇒X-2 <-1 OR X-2> 1
X-2<-1⇒X-2+2<-1+2⇒ X< 1
OR
X-2>1⇒X>1+2⇒X>3
THE SOLUTION IS S2 = (-∞,1)∪(3,∞)
The table represents a multiplicative relationship
