Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.

Answer:
A.
Step-by-step explanation:
Perpendicular => so it will have a slope of negative reciprocal to this slope
Slope = 2/3
Now
Point = (x,y) = (6,5)
So,
x = 6, y = 5
Substituting in the slope intercept form
5 = (2/3)(6)+b
5 = 4+b
=> b = 1
So, we have
m = 2/3
b = 1
Putting in the slope intercept equation
y = 2/3x+1
Answer:
<em>-5</em>
Step-by-step explanation:
-31=9+8x
we need to isolate the variable by moving 8x to the left side and -31 to the right side....therefore 8x becomes a negative, -8x, and -31 a positive....so now it would look like...
-8x=9+31
then we work the right side out...
-8x=40
to get x we need to divide -8x by 8 so we do the same to the right side as well....
-8x=40
÷8 ÷8
so...
<em>x=-5</em>
hope this helped you- have a good day bro cya)
