Answer:
x = 4
Step-by-step explanation:
You can eliminate the y-variables by adding 4 times the second equation to 3 times the first:
3(5x +4y) +4(2x -3y) = 3(8) +4(17)
15x +12y +8x -12y = 24 +68 . . . . eliminate parentheses
23x = 92 . . . . . . . . . collect terms
x = 92/23 = 4 . . . . . divide by 23
The x-value of the solution is 4.
Answer:
Option C. 1,024 bacteria
Step-by-step explanation:
We are given that a bacteria culture begins with 4 bacteria which double in size every hour. And we have to find that how many bacteria exist in the culture after 8 hours;
So, Number of bacteria after one hour = 4 * 2 = 8
Number of bacteria after two hours = 8 * 2 = 16
Number of bacteria after three hours = 16 * 2 = 32
Number of bacteria after four hours = 32 * 2 = 64
Number of bacteria after five hours = 64 * 2 = 128
Number of bacteria after six hours = 128 * 2 = 256
Number of bacteria after seven hours = 256 * 2 = 512
Number of bacteria after eight hours = 512 * 2 = 1,024
Therefore, 1,024 bacteria exist in the culture after 8 hours .
