Answer:C. It has only one solution
Step-by-step explanation:
The system of equations is expressed as
y = x + 2
Subtracting 2 from the left hand side and the right hand side of the equation, it becomes
x = y - 2 - - - - - - - - - 1
-x + 3y = 6
Multiplying the left hand side and the right hand side of the equation by - 1, it becomes
x - 3y = - 6
Adding 3y to the left hand side and the right hand side of the equation, it becomes
x = 3y - 6 - - - - - - - - 2
Equating equation 1 and equation 2, it becomes
y - 2 = 3y - 6
3y - y = - 2 + 6
2y = 4
y = 4/2 = 2
Substituting y = 2 into equation 1, it becomes
x = 2 - 2 = 0
The solutions are (0, 2)
You simply do 973-449 to get 524 jars of strawberry jelly
For this case we can make the following rule of three:
4543 -----------> 423970 km ^ 2
x ----------------> 250 km ^ 2
Clearing x we have:
x = (250/423970) * (4543)
x = 2.678845201
Answer:
the population density of mountain lions per 250 kmsquared2 in California is:
x = 2.678845201
nearest whole numberx = 3
Answer:
(1.33,1)
Step-by-step explanation:
1 = 1.5x - 1
2 = 1.5x
x = 2/1.5
x = 4/3 or 1.33
Answer:
4,3,2,6
