Contractions are dilations less than 1 but more than 0, and Expansions are dilations more than 1. 


3/2 : Expansion

1/4 : Contraction

4 : Expansion

0.8 : Contraction

-3 : Expansion

1/3 : Contraction

These should be the right answers.

Solnce55 [7]

In this question they've given us the formula and they just want us to plug in the numbers and get the value.


P is the original value, P=$600


r is the depreciation rate, r=10%=0.1


t is the time in years, t=2


A = P(1-r)^t = 600(1 - 0.1)^2 = 600 \cdot .9^2 = 486


Answer: $486

4x+(x-y/8)=17 and 2y+x-(5y+2/4)=2 by using elimination method
vladimir2022 [97]

Answer:

x=811/238, y=36/119. (811/238, 36/119).

Step-by-step explanation:

4x+(x-y/8)=17

2y+x-(5y+2/4)=2

-----------------------

4x+x-y/8=17

5x-y/8=17

40x-y=136

y=40x-136

------------------

2y+x-5y-2/4=2

2y-5y+x-1/2=2

-3y+x=2+1/2

-3y+x=4/2+1/2

-3y+x=5/2

-3(40x-136)+x=5/2

-120x+408+x=5/2

-119x=5/2-408

-119x=5/2-816/2

-119x=-811/2

119x=811/2

x=(811/2)/119

x=(811/2)(1/119)=811/238

y=40(811/238)-136

y=16220/119-136

y=36/119

x=811/238, y=36/119.
