Answer:
y = ±2i
Step-by-step explanation:
6y^2 + 24 = 0
Divide both sides by 6
y^2 + 4 = 0
Subtract 4 from both sides
y^2 = -4
Take the square root of both sides
y = ±√-4
y = ±2√-1
y = ±2i
Answer:
-2
Step-by-step explanation:
The slope of a line when given two coordinates can be found using the formula
In this case, the first pair of coordinates are and and the second pair of coordinates are and .
Therefore:
= -2
= 7
= 3
= -3
Next, just plug these values into the slope formula from above.
The numerator is 10 (the two negative signs become a positive) and the denominator is -5.
can be simplified by dividing the numerator and denominator by -5 to give or simply -2.
Therefore, the slope of the line is -2.

Step-by-step explanation:
correct on edge
Multiply 8 by a number then subtract 4 equals 16 is how i would write it
Answer:
120 routes are possible.
Step-by-step explanation:
The delivery driver has time to make deliveries at 3 locations among the 6 locations remaining.
So, the number of ways of choosing 3 out of 9 locations is given by :
6P3 ways (permutation because order of locations will matter)
= =
=
Hence, 120 different routes are possible.
