A line is defined by the equation y=2/3x-6. The line passes through a point whose y-coordinate is 0. What is the x-coordinate of
2 answers:
Answer:
The value of x is 9 when y=0
x-coordinate is 9
Passing point (9,6)
Step-by-step explanation:
We are given the equation of line
The line passes through a point whose y-coordinate is 0.
We need to find x-coordinate of passing point whose y-coordinate is 0.
Put y=0 into the equation of line and solve for x
Passing point (9,6)
Hence, The value of x is 9 when y=0

Answer:
Standard form:
Center:
Radius:
Step-by-step explanation:
The equation of a circle in the standard form is
Where the point (h, k) is the center of the circle
To transform this equation this equation in the standard form we use the method of square.
First, we group similar variables
Divide both sides of equality by 4
Now we complete square for variable x.
Take the coefficient "b" that accompanies the variable x and divide by 2. Then, elevate the result to the square:
Now add on both sides of the equality
Factor the expression and simplify the independent terms
Then
and the center is
radius
