Answer: First one: lies in the shaded region of the top inequality, but not in the shaded region of the bottom inequality.
7x + 6y < 42
6y < -7x + 42
y < -7/6x + 7
slope = -7/6....y int = (0,7)...x int = (6,0)...it will be a dashed line...shading will be below the line....so start at (0,7)...and since the slope is -7/6...go down 7 spaces and to the right 6 spaces, and keep doing this and u will cross the x axis at (6,0)
7x + 6y > - 42
6y > -7x - 42
y > -7/6x - 7
slope = -7/6...y int = (0,-7)....x int = (-6,0)....line will be dashed....shading will be above the line...so start at (0,-7) and since the slope is -7/6...go down 7 spaces and to the right 6 spaces...keep doing this and u will cross the x axis at (-6,0)
The Holly is stringing lights around the edge of the patio is 37.68 feet.
<h3>What is a circle?</h3>
It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circular patio has a diameter of 12 feet.
Then the radius (r) will be

Holly is stringing lights around the edge of the patio will be

Thus, the Holly is stringing lights around the edge of the patio is 37.68 feet.
