Answer:
x=4± 5sqrt(2)
Step-by-step explanation:
x^2 – 8x – 34 = 0
To complete the square Add 34 to each side
x^2 -8x -34+34=0+ 34
Take the coefficient of x, and divide by 2
-8/2 =-4
Then square it and add it to each side
(-4)^2 =16
x^2 – 8x +16 = 34+16
x^2 – 8x +16 = 50
We replace the left side with (x + the coefficient of x/2)^2
(x -4)^2=50
Take the square root of each side
sqrt((x -4)^2)=±sqrt(50)
x-4 = ±sqrt(25*2)
x-4 = ±sqrt(25)*sqrt(2)
x-4 = ±5sqrt(2)
Add 4 to each side
x=4± 5sqrt(2)
Answer: Slope: -1/2 y-intercept: 2
Step-by-step explanation:
Subtract 4 x from both sides of the equation. 8 y = 16 − 4 x Divide each term by 8 and simplify. Divide each term in 8 y = 16 − 4 x by 8 . 8 y 8 = 16 8 + − 4 x 8 Cancel the common factor of 8 . Tap for fewer steps... Cancel the common factor. 8 y 8 = 16 8 + − 4 x 8 Divide y by 1 . y = 16 8 + − 4 x 8. y=2−x2. The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Reorder 2 and − x 2 . y = − x 2 + 2. Rewrite in slope-intercept form. y = − 1 2 x + 2.Slope:−1/2 y-intercept:2
1. A. 1908. In the first year, (a year is 12 months), he paid 159 a month so 159 times 12 is 1908. (You are correct on this one)
2. A. 1908. In the second year, (again a year is 12 months), he paid 159 a month so 159 times 12 is 1908.
(Btw : there would be a third year 36/12=3. He would also pay another 1908 in the third year. To get your answer for number three either do the stragety I wrote for it or do 1908+1908+1908+2399=8123 or (1908•3)+2399.
3. C. <span>8123. </span>Well 159 times 36 is 5724 plus 2399 and get <span>8123. That is the total cost of the lease.
Hoped I helped!

Answer:
I don't give answers sorry.
Step-by-step explanation:
What you would do is take 1 and subract the two probabilites from it. The equation should be 
. You can find a common denominator by making it both 15.
Answer: what are your options?
I would say 33=13
