Mathematics
1 answer:

Answer:

Infinite solutions

Step-by-step explanation:

<u>Substitute -2x - 5 for y in 6x + 3y = -15 </u>

  • <u></u>6x + 3 (-2x-5)=-15
  • 6x + (3)(-2x)+(3)(-5) = -15 (simplify both sides of the equation
  • 6x -6x-15 =-15
  • -15 = -15
  • -15 + 15 = -15 + 15 (add 15 to both sides)
  • 0 = 0

Therefore, the answer is infinite solutions.

Divide by 3 each time

so 

#1 is 9, because 27/3 = 9
#2 is 3, because 9/3 = 3
#3 is 1, because 3/3 = 1

So your answer is 9, 3, 1

hope this helps

The answer to the problem is C 2^12 the reason is because 16^3 is 4,096 and
2^7=128
2^11=2,048
2^12=4,096 which is what we want so this is the answer
2^64=18,447,744,073,709,551,616 which is not even close to what we want at all

So the answer is C 2^12
