Which of the following is a point-slope equation of a line that passes through the points (5, 2) and (–1, –6)?
Maru [420]

y - y1 = m(x + x1)

m = (y2 - y1)/(x2 - x1) = (-6 - 2)/(-1 - 5) = -8/(-6) = 4/3

y - 2 = 4/3(x - 5) is a possible answer

y + 6 = 4/3(x + 1) is also a possible answer

The function y = –0.296x2 + 2.7x models the length x and height y that your sister's pet rabbit can jump, in centimeters. How hi
Ne4ueva [31]
To figure out the solution in a problem related to calculate maximum or minimum of something, you've to derive the involved equation, and make it equal to 0, solving the x.

So:
y = -0'296x² + 2'7x
y' = -0'592x + 2'7
0 = <span>-0'592x + 2'7
</span><span>-0'592x = 2'7
</span>x = 4'56

And if we substitute 4'56 on the first equation:
y = -0'296·<span>4'56² + 2'7·4'56
y = 6'16

So the length of the jump is 4'56cm, and the height 6'16cm.</span>

sesenic [268]
(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr
