Answer:
41
Step-by-step explanation:
by using formula D = b² – 4ac, we get
D = 1² – 4(5)(–2) = 41
The answer is 358 but i cant use the number line in this case.
For part 2, you would use 3 thousands, as that is the biggest amount possible so far. The, you would use 1 ten [instead of 16 ones] and then 6 ones bacuse that is the smallest amount.
In this item, we are not given with the figure but knowing that these lines ought to be perpendicular then we will be able to derive the relationship between the slopes of the line.
The slopes of the perpendicular line are the negative reciprocals of one another. If we represent the slopes of the lines as m₁ and m₂, the relationship can be written in the form,
(m₁)(m₂) = -1
We are given with one of the slopes. To determine the value of the second slope then,
m₂ = -1/m₁
m₂ = -1/(2/5)
m₂ = -5/2
<em>ANSWER: m₂ = -5/2</em>
