Solution

- The transformation for reflection over the y-axis is given below:

$(x,y)\to(-x,y)$

- We have been given the coordinate of B to be (-5, -2) as shown below:

- Thus, applying the transformation formula given above, we have:

$\begin{gathered} (x,y)\to(-x,y) \\ (-5,-2)\to(-(-5),-2)=(5,-2) \end{gathered}$

- Thus, the reflected point B' is

$(5,-2)$

- This is shown below:

Answer:

7. 15.5

8. 12

Step-by-step explanation:

Question 7 equation: $\frac{3*1}{2} + \frac{5+2}{2} * 4=1.5 + 3.5 * 4 = 1.5 + 14 = 15.5$ .

Question 8 equation: $(\frac{2*2}{2} * 2) + (\frac{4*2}{2} *2) = 4 + 8 = 12.$
