The function y=10x+100 represents the amount y (in dollars) of money in your bank account after you babysit for x hours. a. Identify the independent and dependent variables.

The dependent variable is the amount of money in the bank account.

The independent variable is the hours you babysit.

Question 2
b. You babysit for 4 hours. Find the domain and range of the function.

domain:

range:

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

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

answer:

c) the x-coordinate of the center of the circle increases by 3
