Answer:
Two
Explanation:
The solution of a system of equations is defined as the values which satisfies both equations.
Graphically, the solutions are represented by the points of intersection between the two equtaions.
In the given graph, we have a circle and a line, we can note that these two intersect in two points.
This means that the system has two solutions
Hope this helps :)

Answer:
54 gallons
Step-by-step explanation:
Let x represent the volume of the full tank.
When the water tank is 30% full;
= 30% of x = 0.30x
when it is 20% empty:
= x - 20% of x = x - 0.20x = 0.80x
The difference is given as 27.
So, we can represent the question on an equation as;
0.80x - 0.30x = 27
Solving the equation, we have;
0.50x = 27
x = 27/0.50
x = 54 gallons
The tank can hold 54 gallons when it is full.
Answer:
3 : 6 : 1
Step-by-step explanation:
The common multiple between these numbers is 9, so divide everything by nine.
Answer:
A.
Step-by-step explanation:
A. When x = 0 (at the y-intercept),
f(x) = 3 . 9^0
= 3 * 1
= 3 so the y-intercept is (0, 3).
