14x - 7y = 8
-7y = -14x + 8
y = 2x - 8/7....so ur slope here is 2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So we have 2 or 2/1....we flip it making it 1/2....we change the sign making it -1/2. So our perpendicular line will have a slope of -1/2.
y = mx + b
slope(m) = -1/2
(-2,5)...x = -2 and y = 5
now we sub into the formula and find b, the y int
5 = -1/2(-2) + b
5 = 1 + b
5 - 1 = b
4 = b
so the perpendicular line is : y = -1/2x + 4 <==
Cancel equal terms on both sides of inequality
7-3x < 13
move constant to the right side and change its sign
-3x<13-7
subtract the numbers
-3x<6
divide both sides of inequality by -3 and flip the inequality sign
answer is: x>-2

Answer: D. Brian and Kendra
Answer:
3.14 ft² or 2,917 cm²
Step-by-step explanation:
To do this, we need to know the expression to calculate the area of a circle.
The area of any circle is:
A = πr²
Where:
π: value of pi, which is 3.14
r: radius of the circle, in this case 1 ft
Calculating the area in units of ft:
A = 3.14 * (1)²
A = 3.14 ft²
Now, if you convert the foot to cm we have:
1 * 30.48 = 30.48 cm
Solvinf for A:
A = 3.14 * (30.48)²
A = 2,917.15 cm²
Y-intercept = (0,2)
x-intercept = (-4,0)
