Name the steps for constructing a tangent line to a circle.

Step 1: Construct a line and connect the center of the circle to the point.

Step 2: Draw the perpendicular bisector of that line.

Step 3: Use a compass to draw a circle. Place it on the midpoint, make sure it reaches the endpoint, and make an arc.

Step 4:   The tangent point will be where the arc intersects the circle.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

answer is  

d.

all of the above

hope you get this right
