Graph A is a function. A function is defined as a graph that has one x for every y value. To verify this, you can use the vertical line test. When a vertical line is held to any portion of the graph, it should intersect the graph only once. This is only true for a parabola, proving it is the function.

Solve for x 2(x-7)=0.2(x+2)+5.11
Kryger [21]

Answer:

Step-by-step explanation:

You start off by rewriting the equation:

2(x-7)=0.2(x+2)+5.11\\

Then you have to factor:

2x-14=0.2x+0.4+5.11

Then you subtract the 0.2x:

1.8x-14=0.4+5.11

Add the positives on the right:

1.8x-14=5.51

Add 14:

1.8x=19.51

Divide:

x=10.84

You get x is approximately equal to 10.84
