the difference of a two digit number and the number obtained on reversing the digit is always divisible by 9 (true or false)

Shkiper50 [21]

Answer:

Yes!

Step-by-step explanation:

I know this from having been a bank teller. But let's examine the math.

Any two digit number can be written as 10x + y.

Reverse the digits would give you

10y + x

Subtract to find the difference.

10x + y - (10y + x)

10x + y - 10y - x

10x - x - 10y + y

9x - 9y

9(x - y)

Yes, it has 9 as a factor, so it is a multiple of 9.

If P (-3,2$ is reflected over the x-axis, then p

padilas [110]

Reflecting a point on the x axis is the same as performing the following transformation:
T -> (x, -y)
Applying the transformation we have
P (-3.2) ---> (x, -y) ----> p (-3, -2)
Therefore, the new point is
p (-3, -2)
answer
p (-3, -2)

Find the shaded area. Round your answer to the nearest tenth.

Fofino [41]

Answer:

${22cm}^{2}$

to the nearest tenth

Step-by-step explanation:

find the area of the semi circle

$\frac{\pi \times 5}{2} = {7.85cm}^{2}$

find area of the whole shape

$5 \times 6 = {30cm}^{2}$

then subtract both areas to get shaded area

$30 - 7.85 = 22.15$

I need the solution

Nataly [62]

The only thing you can do here is to try to simplify, so I'll assume that's what you want to do.

$\dfrac{b^2-a^2}{2a^2+ab-3b^2}$

The numerator is a difference of squares, so it's easy to factorize:

$b^2-a^2=(b-a)(b+a)$

In the denominator, we factorize by grouping:

$2a^2+ab-3b^2=2a^2-2ab+3ab-3b^2=2a(a-b)+3b(a-b)=(2a+3b)(a-b)$

So we have

$\dfrac{b^2-a^2}{2a^2+ab-3b^2}=\dfrac{(b-a)(b+a)}{(2a+3b)(a-b)}=-\dfrac{b+a}{2a+3b}$
