Answer:
See below.
Step-by-step explanation:
<u>Simplify</u>
y - 2 = 5(x - 6)
y - 2 = 5x - 30
y = 5x - 28
Points which lie on the line
(6, 2)
(5, -3)
(7, 7)
2 8 0
<u> x </u><u>3 8 0
</u> 0 0 0
2 2 4 0
<u> + 8 4 0 </u>
1 0 6 4 0 0
So, 280 x 380 = 106400
0.09/10=0.009
we check it: 0.009*10=0.09, so it's right
Depends on what you are talking about, what is A,x,c and b.
If A is an invertible matrix and x,c,b are vectors of correct dimensions you get
Ax=b+c
x=A^(-1)(b+c)
if x is a variable and A,c,b are constants you get
Ax=b+c
x=(b+c)/A
