Answer:
±6i√2
Step-by-step explanation:
Recall that the square root of a negative number is imaginary, which is shown by the use of "i."
Examples: √4 = ±2; √4 = i√4 = ±i2
Then √72 = ±√36√2 = ±6√2, and
√(-72) = ± i√36√2 = ±6i√2
Note that this is identical to the result shown in the problem: √(36·2·(-1) )
Answer:
Issac's dog weighs 19 pounds
Step-by-step explanation:
Let x be Issac's dog's weight
- Translate the problem into an algebraic expression: x + (x + 12) = 50
- Simplify: 2x + 12 = 50
- Subtract 12 from each side, so it now looks like this: 2x = 38
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19
I hope this helps!
Step-by-step explanation:
y = -9x - 45 -5
y = -9x - 50
slope = x coefficient = -9
we can use the point where
x = 0
y = -50
P1 (0, -50)
and when y = 0
-9x = 50
x = -50/9
P2 = (-50/9 , 0)

Answer:
2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional.
Step-by-step explanation:
Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line.
Number 3 does not go through the origin, so number 3 is also not proportional.
Number 5 is proportional since when you divide y by x, it is always 7.
Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.
