Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.

Parallel lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so 3 remains the way it is.

Answer:
I am not sure but i think B so two solutions
Answer:
3/4 or 0.75
Step-by-step explanation:
the equation is in slope-intercept form
y=mx+b
where m is the slope and b is the y-intercept.
you have already found the y-intercept to be -2, so now we just have to find the slope.
slope is also known as rise/run. so if we start at the y-intercept of -2, we can rise (go up) 3 units and then run (go over) 4 units until we reach another point on the line.
so the slope is 3/4 which is also equal to 0.75 units
Step-by-step explanation:
1. Hold up all ten fingers on your hand
2. Count N fingers from the left
3. Lower that finger
4. Read off the answer from your finger. The number of fingers before that lowered finger give you the number of tens in the answer.
