Answer 1

Jess plans to increase the amount of money she saves each month. She can increase her savings in the following ways:


Month
1
2
3
4
5
Option 1
20
22
24.2
26.62
29.28
Option 2
20
22.2
24.4
26.6
28.8
Option 3
20
24
28.8
34.56
41.47


If Jess wants to increase her savings exponentially, which option(s) should she choose?
Only option 1, because it shows equal increases in equal intervals of time
Only option 2, because it shows equal increases in equal intervals of time
Either option 1 or option 3, because they show increases in time by the same percentages
Either option 2 or option 3, because they show increases in time by the same percentages

Which statement best compares the y-intercepts of f(x) and g(x)?
The y-intercept of f(x) is equal to the y-intercept of g(x).
The y-intercept of f(x) is equal to 2 times the y-intercept of g(x).
The y-intercept of g(x) is equal to 2 times the y-intercept of f(x).
The y-intercept of g(x) is equal to 2 plus y-intercept of f(x).

(05.02)

The table below shows four systems of equations:


System 1
System 2
System 3
System 4
4x − 5y = 2

3x − y = 8
4x − 5y = 2

10x − 7y = 18
4x − 5y = 2

3x − 8y = 4
4x − 5y = 2

10x + 3y = 15


Which pair of systems will have the same solution?
System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to two times the second equation in system 1
System 2 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 2 to two times the second equation in system 2
System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to three times the second equation in system 1
System 2 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 2 to three times the second equation in system 2

Question 16 (Multiple Choice Worth 4 points)

(04.05)

Heidi is preparing for the national gymnastics competition. The table below shows the number of hours Heidi spent preparing for a gymnatics competition over a period of five months:


Month
1
2
3
4
5
Hours
2
3.5
5
6.5
8


Did Heidi increase the number of hours of practice linearly or exponentially?
Linearly, because the table shows an equal increase in hours for an equal increase in months
Exponentially, because the table shows an equal increase in hours for an equal increase in months
Linearly, because the table shows that hours increase by an equal factor for an equal increase in months
Exponentially, because the table shows that hours increase by an equal factor for an equal increase in months
