Step-by-step explanation:
2) a= -3/8 and b= -5/3
a×b= b×a
<u>-3</u><u> </u>× <u> </u><u>-5</u><u> </u> = <u> </u><u>-5</u><u> </u> × <u> </u><u>-3</u><u> </u>
8. 3. 3. 8
<u> </u><u>1</u><u>5</u><u> </u> = <u> </u><u>1</u><u>5</u><u> </u>
24. 24
3)a=8/11 and b= -6/11
a×b=b×a
<u> </u><u>8</u><u> </u> × <u> </u><u>-6</u><u> </u> = <u>-6</u><u> </u> × <u> </u><u>8</u><u> </u>
11. 11. 11. 11
<u> </u><u>-48</u><u> </u> = <u> </u><u>-48</u><u> </u>
121. 121
4) a= -9/15 and b= -7/2
a×b=b×a
<u> </u><u>-9</u><u> </u> × <u> </u><u>-7</u><u> </u> = <u> </u><u>-7</u><u> </u> × <u> </u><u>-9</u><u> </u>
15. 2. 2. 15
<u> </u><u>6</u><u>3</u><u> </u> = <u> </u><u>6</u><u>3</u><u> </u> , let's divide both by 3
30. 30
<u> </u><u>2</u><u>1</u><u> </u>= <u> </u><u>2</u><u>1</u><u> </u>

#5
a - 8 = 10 -2a
a +2a = 10+8
3a = 18
a= 18/3
a= 6
#6
p - 11 -2p = 13 - 5p
Combine like terms
(p - 2p) +(-11) = 13 - 5p
-p - 11 = 13 - 5p
-p + 5p = 13 + 11
5p = 24
p= 24/5
p= 6
#7
12x + 3 - 4x - 3 = 8
Combine like terms
(12x -4x) + (3 - 3) = 8
8x = 8
x= 8/8
x= 1
#8
5x -2 + 3x - 4 = 2x - 8 + 2
Combine like terms
(5x + 3x ) + (-2 - 4) = 2x + (-8 +2)
8x -6 = 2x - 6
8x - 2x = -6 + 6
6x = 0
x= 0/6
x= 0
#17
(5-x)/ 5 = 1
( 5-x)/5 * (5) = 1*5
5 - x = 5
-x = 5 -5
-x = 0
Divide both sides by 1so we can eliminate the negative sign
-x/1 = 0/1
x= 0
I hope i help :)
Answer:

Step-by-step explanation:
f(x) + n - translation n units up
f(x) - n - translation n units down
f(x + n) - translation n units to the left
f(x - n) - translation n units to the right
We have

translation 1 unit up (f(x) + 1)

Answer:
The number is 91
Step-by-step explanation:
Let x be the ones place digit and y be the tens place digit,
Then the number would be 10y + x,
We have,
y - x = 8
Possible values of y and x = { (8, 0), (9, 1) }
∵ 0 is not the digit of the number,
Hence, y = 9 and x = 1
Therefore, required number = 10(9) + 1 = 90 + 1 = 91
