Answer:
1. 17,20
2. 40,80
Step-by-step explanation:
1. 5+3=8
8+3=11
11+3=14
14+3=17
17+3=20
pattern is +3
2. 2.5*2=5
5*2=10
10*2=20
20*2=40
40*2=80
pattern is *2
there must be subtraction of multiplication of each two diagonal,
|G|=[12×2-(-6)×0]
=(24+0)
=24ans
If two lines are perpendicular, then the product of their slopes is -1:
![m_r\cdot m_g=-1...(1)](https://tex.z-dn.net/?f=m_r%5Ccdot%20m_g%3D-1...%281%29)
From the problem, we identify:
![m_r=-\frac{4}{3}\text{ \lparen the slope of the red line\rparen}](https://tex.z-dn.net/?f=m_r%3D-%5Cfrac%7B4%7D%7B3%7D%5Ctext%7B%20%20%5Clparen%20the%20slope%20of%20the%20red%20line%5Crparen%7D)
Then, using the equation (1), we calculate the slope of the green line:
![\begin{gathered} -\frac{4}{3}\cdot m_g=-1 \\ \\ \therefore m_g=\frac{3}{4} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-%5Cfrac%7B4%7D%7B3%7D%5Ccdot%20m_g%3D-1%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20m_g%3D%5Cfrac%7B3%7D%7B4%7D%20%5Cend%7Bgathered%7D)
