Olivia started her banking account with $100 and is increasing the account $20 per month. the independent variable

Wee is the independent variable, and deposit is the dependent variable

Step-by-step explanation:

Given that Olivia started her banking account with $100 and is increasing the account $20 per month.

Here the variable which changes independently is the independent variable

Hence no of weeks elapsed would be the independent variable

The dependent variable would be the variable which changes whenever number of weeks changes.

Here dependent variable is the total balance in the account in a particular week

D=100+20n wbere n= no of weeks that eapsed

and D= depositisin in the bank

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
