Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case the points are: (a,2a) and (b,2b) and the slope would be:
m=(2b-2a)/(b-a)=2(b-a)/(b-a)=2
Answer; B.) 2
Yes you are right.
I got 37 on my calculator
If x₁ and x₂ are solutions of the quadratic equation, then we can write it in quadratic factorization:
a(x - x₁)(x - x₂)
We have x₁ = 5 and x₂ = 7
(x - 5)(x - 7) = (x)(x) + (x)(-7) + (-5)(x) + (-5)(-7) = x² - 7x - 5x + 35 = x² - 12x + 35
<h3>Answer: x² - 12x + 35 = 0</h3>
The probability she chooses a number greater than 5 will be 1/2 or 0.5.
<h3>What is probability?</h3>
Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Probability = (Favorable event) / (Total event)
Eleanor randomly decides a number from 1 to 10.
Then the probability she chooses a number greater than 5 will be
Total event = 10
Favorable event = 5 {6, 7, 8, 9, 10}
Then we have
P = 5/10
P = 1/2
P = 0.5
