Answer:
help with what
Step-by-step explanation:
2000 × 15% = 300
300 × 5 = 1500
2000 - 1500 = 500 population after 5 years
Step-by-step explanation:
a.
simply add both equations
x + y = 2
-3x - y = 5
----------------
-2x + 0 = 7
x = -7/2
x + y = 2
-7/2 + y = 2
y = 2 + 7/2 = 4/2 + 7/2 = 11/2
b.
1/2 x + 2y = -13
x - 4y = 8
first multiply the first equating by 2
x + 4y = -26
x - 4y = 8
--------------------
2x + 0 = -18
x = -18/2 = -9
x - 4y = 8
-9 - 4y = 8
-4y = 17
y = -17/4
4, 8, 16, 32, 64, 128, 256, 512, 1,024.
1,024 is the ninth number in this geometric sequence.
Hope this helps!!
