Answer:
Step-by-step explanation:
work backwards to find the factors from the roots then multiply the factors together. y= x² - 24x + 140
Answer: B
Step-by-step explanation: 6-4=2
From the equation, we can tell that left side of the equation has to be less than or equal to 6 in order for the equation to be true.
So first, let’s try n=0.
Plug it in: 2(0)=0 and since 0 is less than 6, it makes the equation true.
Next, let’s try 1. 2(1)=2. This also makes the equation true.
Next, let’s do n=3. 2(3)=6. So this also makes the equation true.
So the answers are:
n=0 , n=1 , and n=3

Answer:
B
Step-by-step explanation:
If you are allowed to use a graphing calculator, this can solve a lot of time. Graphing y = (x - 705)(x - 795) + 800(x - 750)(x - 835) gets us a parabola with x-intercepts of 749.97 and 834.924.
These roots are real and distinct, or choice B.
If you aren't allowed to use a graphing calculator, you can expand and combine like terms to get 801x^2 − 1269500x + 501560475. Looking at the discriminant, we see that (−1269500)^2 - 4*801*501560475 = 4630488100 is greater than 0 and not a perfect square, so it is real and distinct, or choice B.
I hope that helps!
Your answer would be B and C, hope this helps! :D
