Answer:
The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.
The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.
Exponential growth involves a constant multiplicative rate of change.
Step-by-step explanation:
All that apply in the statements are as follows:
(a) The bottle was ½ full at 11:35 a.m. and doubled again after five minutes, which indicates that the bottle doubled at 11:40 am
(b) The bottle was ¼ full at 11:30 a.m. and doubled twice after 10 minutes. These means that the bottle was ½ full at 11:35 a.m. (i.e. five minutes ago the bottle was at ¼ full at 11:30 am, after five minutes, the which is was ½ full at 11:35 am but later became full at 11:40 am)
(c) Exponential growth involves a constant multiplicative rate of change (1.e. the rates of growth is twice every five minutes)

Answer:
Option E.
Step-by-step explanation:
Given information:
Air conditioning = 88
Automatic transmission = 96
power steering = 76
All three = 4
None of these extras = 19
Only air conditioning = 23
Only automatic transmissions = 61
Only power steering = 28
Both automatic transmission and power steering = 11
Place these values and draw a venn diagram as shown below.
Calculation for missing values:
From the given diagram it is clear that the number of cars that had air conditioning and automatic transmission but not power steering is 24.
Therefore, the correct option is E.
Are you trying to solve for x and y?
y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3
now that you have x value, plug into the original equation to find y and check with the other.
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17
