Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
The answer is 60- you find the other angles from the 180 line and subtract
Answer:
82 inches = 984 inches
82 inches = 6.83333
Step-by-step explanation:
divide the length value by 12
82 inches = 6.83333
multiply the length value by 12
82 inches = 984 inches
The x-intercept is point where the graph cuts the x-axis, while the y-intercept is the point where the graph cuts the y-axis. The y-intercept in a straight line equation normally represents some initial amount. Thus the correct answer that can be deduced from our graph is:
x-intercept is 400
y-intercept is 800
Thus the correct description is:

Step-by-step explanation:
x² + 7x − 8 = 0
(x + 8) (x − 1) = 0
x = -8 or 1
