Answer: x = 4,11
Step-by-step explanation:
x^2 - 7x - 34 - 10 = 0
x^2 - 7x - 44 = 0
Factorise it
x^2 - 11x - 4x - 44 = 0
x ( x - 11 ) - 4 ( x - 11 ) = 0
(x-4)(x-11) = 0
x = 4,11
Answer:
Step-by-step explanation:
the passengers of hawaiian airlines in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)
We replace this number in the equation :
Hawaiian : 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (1.800.000) =12294012
Northwest airlines: 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (195.000.000) = 131477501
B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
