Answer:
1/3
Step-by-step explanation:
(-5,4)=(x1,y1)
(1,6)=(x2,y2)
Slope(m)=y2-y1
_____
x2-x1
=6-4
____
1+5
=2÷6
=1/3
Answer:
you would write 2.20x = 22
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
Any solution x will mod 23 will also have x+23n as a solution, for some integer n. Since 900/23 = 39 3/23, we know there are 39 or 40 three-digit integers of this form.
As it happens, 100 is the smallest 3-digit solution. So, there are 40 three-digit numbers that are of the form 100 +23n, hence 40 solutions to the equation.
_____
The equation reduces, mod 23, to ...
10x = 11
Its solutions are x = 23n +8.
