No not all diagonal lines are lines of symmetry! Because if you take a piece of notebook paper and fold it in half the side do not match up! hope this helps :)
Answer:
m = -2
Step-by-step explanation:
This equation is in point-slope form
The numbers added or subtracted by a variable are a coordinate point.
y + 2 --> (0,-2)
x - 3 --> (3,0)
(3,-2)
The slope is represented by the number outside of the parentheses.
Therefore, the slope of the line is -2
Decrease percentage = (120-52)/120 ×100 = 68/120 =56.66..%
On rounding off,
Percentage = 57%

Answer:
Domain: [-8. 4]
General Formulas and Concepts:
<u>Algebra</u><em><u> </u></em><u>I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation
Step-by-step explanation:
From the graph, we can see that our x-values span from -8 to 4. Since both are closed dot, they are inclusive in the domain:
[-8. 4] or -8 ≤ x ≤ 4

Step-by-step explanation:
<u>Step 1: Define</u>
2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y
x = -1
y = 2
<u>Step 2: Evaluate</u>
- Substitute: 2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
- Exponents: 2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
- Multiply: -16 - 6 + 24 + 2 - (-2) + 4
- Simplify: -16 - 6 + 24 + 2 + 2 + 4
- Subtract: -22 + 24 + 2 + 2 + 4
- Add: 2 + 2 + 2 + 4
- Add: 4 + 2 + 4
- Add: 6 + 4
- Add: 10
