<span>The square root of (a * b) is equal to (the square root of a) * (the square root of b)
-32 equals 32 * -1; therefore, the square root of -32 equals the square root of 32 times the square root of -1.
32 equals 16 * 2; the square root of 32 equals ? 16 * ?2 equals 4* ?2
The square root of -1 is i.
Therefore (2? -32) equals 2 * 4 * i * ?2 = 8i?2</span>
Answer:
Step-by-step explanation:
<u>Proportional relationship is:</u>
- y = kx, where k is the constant of proportionality
We have a point (5, 2). it means x = 5, y = 2
<u>Substitute x and y and find k:</u>
Answer:
27
Step-by-step explanation:
Let T be the capacity of the tank.
Since the tank was 1/3 full and ends up 7/9 full.
T - T = 12
Simplifying the left side of the equation, tells us how much 12 gallons fills.
T = 12
Now we solve for T:
T = 12*9/4
T = 27
Answer:
x=-1
Step-by-step explanation:
thing about it. vertial lines dont have a y int unless its on the y axis,
a straight line going through -1,0 would be x= -1
26.25 / 3 = 8.75
