Since the product of the slope is -1, hence the lines are perpendicular
<h3>Parallel and Perpendicular lines</h3>
Two lines are known to be parallel if they have the same slope while if two lines are perpendicular if the product of the slope is -1
Given the coordinates of line 1 passing through (0, 6) and (6, 4), the slope is given as;
Slope = 4-6/6-0
Slope = -2/6
Slope = -1/3
Similarly for the coordinate points (-1, -7) and (1, -1).
Slope = -1+7/1+1
Slope of line 2 = 6/2
Slope = 3
Take the product of the slopes
Slope = -1/3 * 3
slope = -1
Since the product of the slope is -1, hence the lines are perpendicular

Answer:
7(x+5)-(2xy^2)
that's how you would write the equation
Answer:
TILE SIZES
Contemporary tiles are available in a variety of colors, styles, tile sizes, and shapes, which allows you to create a truly personalized space. Tile sizes are dependent on materials and intended uses, and they have increased dramatically over the years. But while there are some standard tile sizes, there are also a lot of manufacturers that make tiles in sizes specific to their in-house designs. Producers offer an enormous variety of products from very small 0.5” x 0.5” mosaic to large 24” x 24” tiles to suit in any house design and satisfy any customer needs.
i would say C. because since its 4 times the radius then you factor in thats only half of the circle then you factor in the other side which makes it 8 hope this is true
substitute the value of the variable into the equation and simplify.
the answer is 3.
