Answer:
M = -2/3
Step-by-step explanation:
2x + 3y = -12 (subtract 2x from both sides)
3y= -2x -12 (divide everything by 3)
Y = -2/3x - 4
M= -2/3

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2/3x - 1
x = 2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(2) = 2/3(2) - 1
- Multiply: f(2) = 4/3 - 1
- Subtract: f(2) = 1/3
X+(4x-20)=180
=>5x-20=180
=>5x=200
=>x=40
B is equal to 51 because angles in a right angle add up to 90
