For each input (number), there is exactly ONE output. So the given table does represent a function.
If <span>f(x)=925x+1000 and x=24, then f(24) = 925(24)+1000 = 23200.</span>

The base of the triangle ABC is 12 units.
Step-by-step explanation:
Step 1; First we need to identify which side is the base of the triangle. In this given triangle side CB is the base. So we plot points C and B on the graph. Coordinates for C are (-4, -3) and for B are (8, -3). We need to find the distance between the 2 edges of the triangle.
Step 2; To find the distance of CB, we use the formula;
Distance = √ (x2 - x1)² + (y2 - y1)².
Distance between C (-4, -3) and B (8, -3) where C is (x1, y1) and B is (x2, y2).
Distance = √(8 - (-4))² + (-3 -(-3))² = √12² + 0² = √12² = 12 units.
Similarly, triangle ABC's height equals 10 units.
Elimination
2 ( 2x -y=5) multiply = 4x -2y=10
3x +2y=4
* add the X's and the 10 and 4 7x=14 * divide by 7 giving you
x=2
*and then plug back in
3(2) +2y =4
6 + 2y = 4
2y= -2
y= -1
the order pair is ( 2 , -1)
