Answer:
A. -11x + 7y
Step-by-step explanation:
4y - 9x + 3y - 2x
4y + 3y = 7y
-9x - 2x = -11x
-11x + 7y
I hope this helps!
Answer:

area of a circle= pi×radius^2
A= pi×9^2
Answer:
7; 40
Step-by-step explanation:
No symbol for the term that you are solving for . I will use β
V = βwh Divide by (wh)
V/(wh) = β
β = V/(wh)
β = 735/(21 × 5) = 7
β = 3312/(11.5 ×7.2) = 40
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
We find the slope of the line:
Thus, the equation of the line is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)
2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
