Answer: g is a geometric sequence.
Step-by-step explanation:
Each year since then, her account accumulated interest amounting to
15% of the balance in the previous year.
15% = 15/100 = 0.15
Since the balance is increasing each year, then the constant factor by which it is increasing is 1 + 0.15 = 1.15.
This factor of 1.15 is a common ratio. This means that the sequence is a geometric sequence since it is increasing by a common ratio.

Step-by-step explanation:
x is the score she got on the fifth test.
Since her average score is 88, the sum of all five tests is 5×88.
x + 87 + 75 + 93 + 85 = 5×88 = 440
x = 440 - 87 - 75 - 93 - 85
x = 100
She got a 100 on her fifth test.

Answer: see below
<u>Step-by-step explanation:</u>
Write each equation in y = mx + b format where m is the slope and b is the y-intercept.
Left side: -4 ≤ x < -1
If you continue the line through the y-axis it will pass through (0, 4) --> b = 4
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (4) --> y = -x + 4
Right side: -1 < x < 4
The line passes through (0,0) --> b = 0.
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (0) --> y = -x
