A^2 + b^2 = c^2
9^2 + b^2 = 12^2
81 +b^2 = 144
-81 (subtract 81 from both sides of the equation)
b^2 = 63
b = square root of 63
Answer:
The equation of the line would be y = -3/2x - 1
Step-by-step explanation:
In order to find this, we first need to find the slope of the original line. We do this by solving for y.
3x + 2y = 8
2y = -3x + 8
y = -3/2x + 4
Since we know parallel lines have the same slope, we know our new line has a slope of -3/2. We can now use that along with the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - -4 = -3/2(x - 2)
y + 4 = -3/2x + 3
y = -3/2x - 1
Answer:
equation of line:
y = mx + b....equation(1)
slope = m = -1/4
y-intercept = b =?
put point(12,5) and slope (-1/4) in equation(1)
5 = (-1/4)(12) + b
5 = -12/4 +b
5 = -3 + b
5 + 3 = b
b = 8
putting values of b and m in equation(1)
y = (-1/4)x + 8
Step-by-step explanation:
12 miles - 132 minutes
1 mile - 132/12 = 11 minutes
66 miles = 11 x 66 = 726 minutes.
Hence your requires answer is 726 minutes.
