B
rearrange into standard form : ax² + bx + c = 0 (a≠ 0)
2x² - 3x - 2 = 0
(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )
x - 2 = 0 ⇒ x = 2
2x + 1 = 0 ⇒ x = - 0.5
Answer:
N(h) = 2h + 6
Step-by-step explanation:
A model of the number of people that Denis can invite to his party:
N(x) = x/25.............(1)
Where x = amount of money saved
Amount of money saved can be modeled by the equation:
M(h) = 50h + 150...........(2)
In the above model, h = number of overtime hours
M(h) = amount of money saved = x
Therefore equation (1) can be re - written as:
N(x) = M(h)/25.................................(3)
Substituting equation (2) into equation (3)

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h overtime hours this week can be expressed as:
N(h) = 2h + 6
That would be 180 / 1 1/8
= 180 / 9/8
= 180 * 8/9
= 20 * 8
= 160 boxes Answer
Using the cosine rule, a² = b² + c² -2 bc cos θSImplifying the equation in terms of cos theta,
cos(θ) = (a² + c² - b²)/(2bc)
(a² + c² - b²)/(2bc) > 0 a² + c² - b² > 0
assuming b and c are non zeros, the resulting inequality should be
a² + c² > b²
THe appicable inequality is a
