Let u be the set of all words containing 7 letters(26 letters to the power 7)
So for 4, first thing you need is slope. Choose 2 points. I am choosing (8,2) and (6,3) So, then its the second y term subtracted by the first y term over(Or divided by) the second x term subtracted by the first x term.
3-2/6-8 or 1/-2 or -.5 (negative 0.5)
Now, time to find the yintercept(yint). So, choose one of the points, Im choosing (8,2), and put it into slope intercept, but leave yint as b.
(2)=-.5(8)+b
simplify
2= -4+b
subtract -4
b=6
So, your answer is y= -0.5x+6
I will right number 6 in anoher answer
Answer:
x=35
Step-by-step explanation:
3x+7+68=180
3x+75=180
3x=105
x=35
Answer:
-1/2
Step-by-step explanation:
y2-y1 4-5 -1
--------- = -------- = --------
x2-x1 6-4 2
43.8 + x = 46.59
x = 46.59 - 43.8 ( when you move a number to the other side, flip the sign)
x = 2.79 (answer)
hope this helps
