Answer:
B'(1,4)
Step-by-step explanation:
after reflection in line c....line c is perpendicular bisector of B' and B
find the slope line between trough B and B' its _1 hence slope of the perpendicular bisector should be 1... equation of line c is
![y - 3 = 1(x - 2) \\ y = x + 1](https://tex.z-dn.net/?f=y%20-%203%20%3D%201%28x%20-%202%29%20%5C%5C%20y%20%3D%20x%20%2B%201)
Answer:
a=
or ≈ -3.66
Step-by-step explanation:
-(3a+4)=7
-3a-4=7
<em>Add 4 to both sides</em>
-3a=11
<em>Multiply both sides by -1</em>
3a= -11
Divide both sides by 3
a= ![-3\frac{2}{3}](https://tex.z-dn.net/?f=-3%5Cfrac%7B2%7D%7B3%7D)
