Answer:
1. (2/3, -2)
2. (-3/2, 3)
3. (9/4, 3)
4. (4/5, -1)
5. (doesn't show the question, ill answer if u tell me what it is)
6. (4/3, 4)
7. (-3, 3/2)
8. (-2, 3)
9. (3, -2)
10. (doesn't show the question, ill answer if u tell me what it is)
Step-by-step explanation:
I'm a master at graphing :3. Also just if you forgot or don't know it's like (x, y). Hope I helped :)
the degree is the largest exponent on the variable, so it would be 3-
Tan = o/a and = 3/4 so the opposite is 3 and the adjacent is 4

Let the number be (10 x + y)
Then, 10 x + y = 3 * (x + y) (given)
Or, 10 x + y = 3 x + 3 y
Or, 10 x - 3 x = 3 y - y
Or, 7x = 2 y
Or, x = 2 y / 7 ( Eq. 1)
Also, 10 x + y + 45 = 10 y + x ( given)
Or, 10 x - x = 10 y - y - 45
Or, 9 x = 9 y - 45 ( Eq. 2)
Substituting the value of x from (Eq. 1) in (Eq. 2), we have:
9 * 2 y / 7 = 9 y - 45
Or, (9 y ) - (18 y / 7) = 45
Or, 63 y - 18 y = 315
Or, 45 y = 315
Or, y = 7
From (Eq. 1),
x = 2 * 7 / 7 = 2
So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27
Answer
Check:
Sum of the digits = 2 + 7 = 9
9 * 3 = 27 ✓
Adding 45 to the number 27, we get 72. So, the digits get reversed.
The first problem is true because with multiplication it doesn't matter which order it is in.
The second problem is false because you will get a different quotient depending on which numbers are on which side of the equation.
