Answer with explanation:

The two equation which we have to solve by graphing are:

1 → 0.2 x-0.5 y=10

2 x-5 y=100

2 → 0.5 x-0.3 y=15

5 x -3 y =150

$\frac{2}{5}\neq \frac{-5}{-3}\neq \frac{100}{150}(\frac{2}{3}$

So,the system of equation has unique Solution.

x=23.68

y= -10.53

None of these.

Answer:

The error made is that the graph of $y=x^{2} +3$ is a vertical translation up by 3, instead of down.

Step-by-step explanation:

Exponential functions, when they are graphed, use the function $f(x)=a(x-h)^{2} +k$ .

In the equation, k expresses how much the graph shifts vertically. In this case, the function shifts vertically up by 3 from the parent function, $y=x^{2}$ . So, the translation is actually 3 units up compared to the graph of $y=x^{2}$ .
