Answer: x = -1 and y = -2
Step-by-step explanation:
So if you know y = x-1 you can plug that in where y is in the first equation
-4x + 3(x-1) = -2
Distribute the 3:
-4x +3x -3 = -2
Combine like terms:
-x -3 = -2
Add 3 to both sides:
-x = 1
Multiply by -1:
X = -1
Then you plug that into the other equation to get y=(-1)-1
Which is -2
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute
3 minutes
Answer:
C
Step-by-step explanation:
Since the output is just the input multiplied by 3, the output will be 15.4*3=46.2, or answer choice C. Hope this helps!
The answer would have to be -4
The volume of the figure is 54 cubic units
<h3>Area of a rectangular prism.</h3>
Since we are not given a figure, we can assume it as a rectangular prism:
Area of the rectangular prism = a²b
- a² is the base area
- b is the height of the prism
Given that a = 3 units and b = 6 units, the required volume is expressed as:
V = 3² * 6
V = 9 * 6
V = 54 cubic units
Hence the volume of the figure is 54 cubic units
