Answer:-2
Step-by-step explanation:
Log3(1/9)
Log(1/9) ➗ Log3
Log(1/3^2) ➗ Log3
Log3^(-2) ➗ Log3
-2Log3 ➗ Log3
-2(Log3 ➗ Log3)
-2
You said each equation but only posted one.
The standard form takes the place of
Ax + By = C.
y-5 = -3(x+2)
y - 5 = -3x - 6
y = -3x - 6 + 5
3x + y = -1
Done.
To solve the question, use the equation y=mx+b. Since you already know the slope (m), all you need is to find the b. Plug in the x and y from the point (9,2) and m:
2=3(9)+b
2=27+b (subtract 27 on both sides)
b=-25
The equation is y=3x-25
