19. -x-2 = 2/3x + 3
5/3 x + 3 = -2
5/3x = -5
x = -3
20. none are correct, you can double check me by plugging in the x and y values in the coordanates into the first problem none of them worked out in the first equasion so no need to test the second
21. -3 is the answer, capable of being done by using desmos
Answer:
The average rate of change from 3 to 6 storms = 0.04
Step-by-step explanation:
Let number of Storms = N
And Predicted Gas Price = P
it is required to find the average rate of change from 3 to 6 storms.
At N = 3 ⇒ P = $2.44
At N = 6 ⇒ P = $2.56
So, the average rate of change = 
Step-by-step explanation:
3x + 5 = 36
3x = 36 - 5 = 31 (subtract 5 on both sides)
3x = 31
x = 31/3 (divide 3 on both sides)
Hence x = 31/3.
The volume of the prism ... L x W x H ... is 0.04 of the volume of the tank.
If the prism is rectangular, then its width is (0.04 of the volume of the tank) divided by (L x H of the prism) .
5. A
6. No, 1/5(25x+15)-7x= -2x+3
-2(x-5)= -2x+10
-2x+3 is not equal to -2x+10
