Answer:
pliz send me the formula, only dsn I can solve your answer
-6.5x + 3 < 19 - 2.5x
-6.5x + 2.5x < 19 - 3
-4x < 16
-4x/-4 > 16/-4
x > -4
8 out of 12 people were happy.
8/12 reduces to 2/3 of the people were happy.
Multiply the total people surveyed by 2/3:
126 x 2/3 = (126 x 2) /3 = 252/3 = 84
84 people were happy.
the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b ) is a point on the line
y + 1 =
(x + 5) is in this form
(a) with slope = 
(b) point on the line = (- 5, - 1 ) = (a, b)
