Answer:
y+4=6(x+7)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=6(x-(-7))
y+4=6(x+7)

Answer:
Step-by-step explanation:
a = 2i + 3j + zk
b = xi + 1j + 4k
Given a X b = 6i -14j +5k
a X b = | i j k|
|2 3 z|
|x 1 4|
a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k
equate the coefficients of i , j and k
12- z = 6; implies z = 6
8 - xz = -14 implies 8 - 6x = -14
2-3x = 5 implies 2 - 3x = 5 implies x = -1
8.3% you need to do change divided by the original then multiply by 100
